    I'm not sure how that helps, though. On one hand, you could indeed consider someone rich wouldn't steal from people because they don't need to, but on the other hand, why do they need money, then?

    well there's a booming business renting luxury goods to "influencers" on tik-tok and friends.  You can even rent a fake "private jet" for your videos.  this is just a slightly older school method of that, I guess.  Most actual rich people do not flaunt their wealth, because they don't waste their money on things like sports cars the depreciate faster than a cybertruck in a car wash.  Tommy was kind of the epitome of "conspicuous consumption" like that.  This guy is the low-rent version of him.

  2. that pcb is not running any games, and cannot run a single game.  it is missing... everything.  there's no power supplies to run the FPGA.  there's no RAM (they do show a DDR3 or DDR4 RAM module plugged in, but it is not connected to the FPGA, and it is simply too far away from it to actually function if it was even hooked up (dat speed of light).  There's no HDMI drivers of any kind.  Just... EVERYTHING is missing that is required to make it work. 

     

    Checking out the videos (I downloaded and saved all of them in case they poof), they show decent shots of the PCB front and back at various points, and there aren't even any traces going to most of that stuff!  There's no connections to the cartridge slots, controller ports, video ports.  The two HDMI sockets on the back appear to just be connected in parallel to each other, like a passthrough.  The front USB connects to the back USB like a passthrough, which is how he can run a controller through it.  It is not connected to the FPGA in any way.

     

    I laughed so much at their "demonstration" video-  you can see him turn the computer on behind the monitor at the start!  And then he fakes the whole "blowing in the carts" thing, and hits a button on the controller to make it display the cart is installed.  Then there's that obvious jump cut when the game starts.  come on.  who are you fooling?  If you look, the board isn't even on.  The fan's not turning (we'd hear it easily, with all the other ambient noise) and the LEDs aren't lit.  It's just a fancy USB passthrough for the controller.

     

    There is only a single 5V supply (lol) on the board.  The FPGA will require something like 1V at 10-15 amps, along with 3-4 other voltages for RAM, HDMI, and other doodads.  There is a CF card and an SD slot on the left, but you can see that they are both connected to an arduino and CPLD each and nowhere else.  There's another arduino CPU and CPLD by the FPGA which appears to do nothing; it does not seem to be connected to anything.  The FPGA is literally not connected to anything either- there is a shot where the chip isn't present and it's just a bare footprint.  A couple big ceramic caps around the FPGA for... some purpose.  The FPGA needs a lot of decoupling capacitors around it- and more importantly UNDER it- probably 40-60 or more.  Those obviously aren't present.

     

    The LEDs make me laugh.  There's 8 LEDs and two chips to run them, probably something like a 555 timer and a binary counter or similar to make blinkenlites.  They do not connect to anything except 5V.

     

    Also, the PCB is 2 layers.  a real board to use that FPGA would need to be at least 8 layers probably.  I bet the PCB house that made and assembled it was like "wtf" when they saw it.

     

    Going by the videos and PCB, this cannot work as it sits, and never was designed to work.  They just threw some random parts onto a PCB and made it look like they knew what they were doing.  They don't.  I noticed too that the heatsink is way too high up off the pcb, so it's probably just hovering over that FPGA.  But that's fine- the FPGA isn't even connected to anything so it won't be getting hot or anything. 

     

    It is debatable if this is a step up or down from the retroPOS.  They did make a cardboard "PCB" and glued electronic parts on it.  This is a real PCB, and has parts soldered to it, but those parts aren't even connected- at least the "important" ones (controller ports, cart ports, RAM, FPGA).  

     

    If you give these dorks money, you most likely are not going to see it again, and you won't be getting an FPGA system that works unless they totally redesign it.

  3. that evel game is probably the most well tested one they have.  first it was released a decade ago as a freemium title so it would've been debugged then, and second they showed this game off on nearly every video with 4 people playing the minigame.  what else is left?  I guess custom controller skins with button function hints!   "press a button to jump"  "press another button to accelerate".  it isn't like this game is difficult to figure out.

    @kevtris Thanks for the reply. Even if you do not remember this specific case, have you back then ever (or maybe even frequently) modified ROMs to make them work with the then existing hardware or emulators? Or do you know that this happened? If these ROMs are still floating around, we should try to sort them out.

    I never hacked any ROMs to make them work, except the FA ones, I added an extra empty bank with a single bankswitch to make them 16K but that was only for my own "bankzilla" use and I never released those.  I don't think I released a hacked smurfs image but who knows, it was 25+ years ago now.

    Maybe @kevtris does remember? 

     

    In general, the Coleco F8 bankswitching code looks odd. There are lot of padding NOPs around. Maybe the code was prepared for multiple bankswitching options? Maybe many of the dumps we know were hacked to F8? Interesting for sure...

    unfortunately I don't remember a whole lot, but I do remember tracing the pcb out.  it used 4 TTL chips and an EPROM from what I recall.  Checked around and I can't find the PCB right off the bat so I might've given it to a friend (I put it back into the cart shell, it didn't work when I got it since a trace got eaten away somehow so I fixed it).

     

    the NOP padding could be a "landing zone" so that a slow bankswitch wouldn't crash it, switching halfway through the next instruction or similar.  They could've just been overly cautious of speed limits on the bankswitching hardware too.

  6. I did a little investigating and cornhole was first mentioned on page 40 (well it was on 26 but only in passing and not as an amico title)

    and tommy was very quick to follow up with a probable lie:

    then some lame "poll" designed to drive tons of posts from the hopefuls... still almost nothing about it yet.  guessing he was talking about it some on "interviews", however. (page 114)

    when I re-read some of this stuff I just have to shake my head.  uttered again by tommy on page 149. card games are the most played genre on earth! woowwww

    Quote

    Yep!  Our software line-up is definitely super unique.  And yes... I think people are overlooking that fact.

    In Sports... remember it's recreational sports as well!  So pool, darts, bocci, shuffleboard, cornhole, etc.!  All fall under that category as well.

    The car game GrudgeQ spoke about would be considered New IP's.  Really unique experience that can only be played on Amico because of our controllers.

    There are so many amazing Retro games... I don't think we'll ever run out!

    What is the most played video game genre on the planet Earth?  Some might think Match 3 games?  1st person shooters?  MMORPG's?  Nope!  Not even close.  It's card games!  Yet not a single home console has ever focused on them.  Why?  Because they don't have a screen on the controller... and folks who typically play consoles are not interested in typical traditional card games (not including things like Magic & Hearthstone, etc.... those are hardcore experiences... I'm talking traditional playing card deck games).

    things really take off on page 151 about it when the hopefuls finally notice it and tommy has to go on about it.  so maybe it wasn't a cheesy suggestion after all and I was wrong on that.  I just remember there being a big explosion in interest that seemed odd. looks like tommy laying on the bullshit thick was the reason.  Note the search hashes on the right in the scroll bar. Fastest growing sport in the world, don'tch'a'know!

    weirdly it doesn't get mentioned again until page 203 or so with just a mention in passing and no followup.  On 207 drops this one:

    Being 100% Italian I can tell you that Bocce is pretty cool. 

    It's similar to shuffleboard... BUT WITH BALLS!



    Yeah... people dismiss the fact that a lot of recreational sports can't be played in most places for 4 to 5 months out of the year.  And those months are when most family gatherings occur!  Thanksgiving, Christmas/Hanukkah, New Year's, etc.  Having simple fun access in your living room to outdoor type family games like horseshoes, cornhole, bocce, shuffleboard, etc. is going to make Amico very special and very attractive to folks. 

    Something that most people completely overlook, but I've been focusing on since the beginning.

     

    Never minding the fact tommy is only 50% italian at best (mom is canadian, dad italian, born in the USA), apparently tommy only thinks people celebrate holidays during winter months and that is perfect time for amico!  No one celebrates easter, 4th of july, labor day, or memorial day and plays outside games then.  No one ever gets together on weekends in the summer either.  nope!

     

    We never did hear more about bocce ball, shuffleboard (lol) or horseshoes again.  People overlooked these since there's very little interest compared to other games.  You're not going to see esports contests for bocce ball or horseshoes.

    Before this failure, I had never even heard of Cornhole before, why would anyone think this is a hit-selling idea? 🤔

     

    I member how someone mentioned cornhole being a "killer app" (lol) for amico, and everyone glommed onto it and that's how it came to be.  "NO ONE makes a good cornhole game!"  which isn't true, there's several decent ones and they are better and cheaper than the turd that amico got.  They talked about horse shoes and bocci ball too (it's italian, don'tcha'know!) but cornhole won out for some reason.

    Given the proto board in the video sports a Cyclone V SX which matches the SE in the DE-10 Nano and in addition it has transceivers I fail to see how it could cost less.

    Aka I cannot understand how they can support any scale ... maybe there was a pellet of these things sitting around? 

    Granted we are not talking huge numbers so maybe they secured a few thousands??? At any rate the price of the SoC per see is supposed to be higher than the SE in the DE-10 Nano, plus there's the board and all the other components ... 

    You mention "ewaste and have been cleaned up and reballed" ... how sustainable is that and why would not Analogue tap into the same source? Too much hassle? Too much support? (well then these MiSTer clones would go through the same issues).

     

    Even their 128MB RAM module is so much cheaper? Are the other vendors overpriced? Or maybe it's some volume discount????

    I checked out the video and paused it and single stepped it to get a good look at the FPGA.  it seems to actually be the same FPGA that's on the DE10 after all.  my DE10 here has a -7 speed grade rated part, and the clone board does too.  One interesting thing about the DE10 board's FPGA is it is specially marked.  the part number ends with 7NDK  while the one on the clone is just 7N.  the "DK" stands for "development kit" and you should only find these on dev kit boards like the DE10.  I wonder if intel does this to detect grey market chip sales?   Since it is using the same speed grade FPGA after all, theoretically it should be compatible with all the cores, at least the FPGA should be.  Jury's out on the rest of the board but that shouldn't be difficult to get right.

     

    It's a mystery to me where they are getting the chips.  The problem with pulled/reballed parts is they have been used once, and it's a big hassle to pull and reball them, and also the supply is uncertain.  you might get a bunch of them when i.e. telecom equipment is retired and never get more.  also, reliability might not be great since they will have 10-20K hours on them, and were heated up three more times to pull, reball, and install them on the new board. 

     

    the RAM module seems in line with what I'd expect.  the RAM chips are a few bucks each and the PCB is pretty cheap, so $15 seems reasonable.

    That’s just an opinion, if it is really as cheap as they say if the more demanding cores don’t work or have some limitations it would be fine to many people as long as they know before buying, like MiST to this day (they have their own rebuilt neogeo core).

    I have a MiSTer and have never once fired the Saturn or N64 cores and I do have 2 Saturn and 2 N64 in the house … to each his own.

     

    Terasic can only support the DE-10 nano board for hw issues on their side but that’s it and they are on par with other dev boards manufacturers (like Arrow).

     

    On other news if those people can really source the 100k le Cyclone V (as in five Roman numeral and not the letter as spelled in the above video) for that cheap I have to believe Analogue would do the same for beefed up offerings … @kevtris did the price of the fpgas of that size plummeted recently? You know with more competitors (Trion etc..).

     

     

     

    I suspect these are pulls from ewaste and have been cleaned up and reballed.  Not that there's anything wrong with that- they probably got them for practically free on something like cell phone equipment when it was upgraded.  The problem with this, though is they might not be the same speed grade.  The de10 has a -6 part which is the fastest;  the picture I saw strategically covered up the chip's markings so I cannot tell what speed grade it is using, but I wouldn't be surprised if it was the -8.  This means that certain cores might not work or will be flaky if the speed grade is slower.   I noticed the on-board jtagger is gone too and has been replaced with a plain old jtag port.  this would save some cash and unless you're a developer this doesn't matter too much.  I don't know what RAM it is using, it looks similar to the official board so the DDR3 is most likely fine.  There could be other minor things changed too to save a bit of cash. 

     

    So I suspect it will work fine for a lot of things but might fail on the more demanding applications.  there might be other things like lower spec power supplies too.  If people know what they are buying I don't see a problem with it, just hope it doesn't cause a support issue.  IF they can obtain -6 parts it would be possible to have essentially a 1:1 clone though.  so it will all hinge mainly on which chip is on there.

  10. I was unaware that some cartridges might take awhile to become ready, so I just test once.  it's been changed to test for 2 seconds, and show the error screen, but it will keep rescanning continuously and will boot if the cartridge ever becomes ready eventually.  the fix will go out with the next update.

    So @kevtris what would be your best guess on when they would need testing done and started manufacturing to make it by the holidays?

    they would need to probably start ordering parts today if they hope to have it all.  then figure start assembling in august at the very very latest.  so they got some time to debug it, but they'd have to hire another engineer probably to redo the design; guessing lots of parts are EOL/not available/long lead times so they will need to do some major redorkulating.  also, the extremely poor battery life and constant disconnections need to be addressed.  the former probably is not fixable without hardware changes (bigger battery, etc) and the latter SHOULD be fixable with software, but that'd require debugging and someone to do that work.

     

    I'd be surprised if the controller gets made at this point.

    And the Bluetooth and/or any other wireless communication?  

    yes, those will need separate tests.  they will need a total of four tests I think: safety test (battery, charger),  emission test for bluetooth (intentional radiator), emission test for wifi (intentional radiator), and general EMI/RFI emissions (unintentional radiator).

  12. yeah the only real way to ID games would be to CRC the upper 8K or so but even that isn't bulletproof- many mappers can start up in any bank so that means you'd have to store a CRC for every possible bank.  though, for this application it isn't quite that bad- it only has to identify a fixed set of games and not the entire library.  still it doesn't help the flash cart situation.  it would be possible to have some kind of register that can be written to enable the required expansions, but that'd require flash cart devs to add that to their code.  I actually do have that feature in there- the NSF player hack I did for the powerpak uses it, and automagically turns the correct expansion chips on for you.

    @kevtris Thanks for popping by to clear that up.  I know you're generally very busy and I'm sure someone(many?) have asked this before, but before analogue you did the HiDef NES kit which was fantastic and is fantastic.

     

    I'm aware of a few oddities with that one, such as not saving your preferred sound channels for expanded audio (VRC 6) etc.  Was there ever going to be a like final update to that to flesh out any untied ends on that one or, since it's not like game breaking or system stalling, it's at a happy place where it is at and that's that?  I've been wanting to ask about this for some time, but had no idea how to reach out.

    that wasn't a bug, it was conscious design decision.  the reason is someone will turn one of those on, forget about it then wonder why there's weird noises coming out of their tv.  so the solution is to make them reset when the power is cycled.  there isn't a super good solution to the problem, and that was the one I came up with.  (playing non-expansion sound games with one or more expansions turned on can cause the expansions to still make sound anyways, when the games write to their mapper chips which tend to mapped into similar areas.  the best solution would be to somehow ID/fingerprint the game first and automatically turn the correct ones on, but that won't work for flash carts since their menus run first and would defeat any kind of identification.  also I was totally out of space in the FPGA.  it's a bit over 95% full right now)
