+MacRorie Posted December 10, 2018 Share Posted December 10, 2018 That's not correct. The firmware only defines the display of the menu. So the jumper can only change that. A PAL Encore or UnoCart can play NTSC games and vice versa. But for NTSC games displayed in correct colors you need a NTSC console, and for PAL games you a need a PAL console. The flash carts make zero difference here. Fair enough.

HDTV1080P Posted December 10, 2018 Share Posted December 10, 2018 (edited) https://www.thebrewingacademy.com/ Your understanding is incorrect. The 2600-UNO supports .3E files up to 256k in size. There is no limit to the size of the SD card that you can use on the UNO. Although, 1G is probably more than sufficient for most collections. The Harmony Encore is a very excellent product. I do not see the need to force comparisons between two excellent products which have very different price points. Again, feel free to ask questions before posting incorrect statements, 1. Yes, updates can be done via the SD card. That is the beauty of it: You do not need any additional hardware or software to update the 2600-UNO. 2. You are correct that, unlike the Harmony Encore, the 2600-UNO cartridge does NOT require a firmware upgrade to play PAL or NTSC ROMs, all you do is change a jumper located via a very easily accessed hole in the cartridge shell. 3. No need to disassemble it at all. It is quite easy to change. In fact, it will even run PAL ROMs on an NTSC monitor (albeit in black and white). You should enjoy using your Harmony cartridge. I have one as well. Again, why the need to cast aspersions? The UNO-2600 will run just about anything you throw at it, can be updated via the SD card and it just as robust as possible for a multi-cart. It is also $40 (plus shipping), so enjoy both. As for the Ultimate Cartridge, that is not for the 2600. It never has been. It is for the Atari 800/XL/XE series of computers on have been produced by a number of people. I have been producing it for the creator since 2015. If you have an Atari 8-bit computer, I highly recommend one. Thanks for the updated information on the official website link. I was getting my information from a UnoCart EBAY dealer that said the following https://www.ebay.com/itm/Atari-2600-SD-Card-MultiCart-works-on-2600-7800-plays-most-ROMs/283206485702?hash=item41f06c06c6:m:mAllds0JyCjztYua7dw-uWA:rk:1:pf:0 "The UnoCart -2600 is an Atari cartridge emulator. It supports cartridges with up to 64k of ROM and 32k of RAM." However you gave me the correct information at 256k in size. However that is half the rom storage space of the Harmony Encore at 512k. The EBAY dealer also said "The jumper on the back of the board allows you to select whether the cartridge uses NTSC or PAL/PAL60 for the built-in menu. You can remove the jumper completely if you are using a NTSC TV." That sounds like one needs to take the cartridge apart on the back of the board. However looking at their updated pictures it looks like the jumper is external and can be accessed on the top of the cartridge shell. The Harmony Encore firmware is upgradable by SD and USB port. Plus it offers 512k rom bank switching which is twice the storage capacity of the UniCart 2600. However the UnoCart does have the advantage of using a external jumper to change from PAL to NTSC and not needing to change the firmware. Its also a little bit cheaper in price. I plan on continuing to use my Harmony Encore because of the 512KB of rom capability, USB port, and I heard its currently 100% or 99.9% compatible with all games. However its awesome to see competition in the market that can lead to improvements in products and price.

The CPUs are different, so you cannot compare directly, but IIRC Encore runs at 60 or 70MHz and Unocart at 160MHz. But if that ever really makes a difference, is completely unknown. And in a few years, there will be another flash cart with maybe 250 or more MHz.

HDTV1080P Posted December 10, 2018 Share Posted December 10, 2018 It is also the quality of the firmware and software that makes a difference. If one product has better hardware but poorly written software with bugs, then the slower cartridge would be better. I would need to purchase both to compare the software. So it sounds like the UnoCart 2600 might coexist with the Harmony Encore unless one goes out of production. I am looking for quality first and price second when selecting a multi-cart.

Have you tried to use a different formatter for larger SD cards? I use one I think called SD formatter and it allows me to format higher capacity cards like a 64gb for example in Fat32 structure. Very possible you could do the same with larger capacity cards and have them work on things like the UNO etc. This is what I'm using with my RHEA on my Saturn. It normally can't support anything larger than like 16gb. But that is because the Windows OS by default doesn't let you format to FAT16 above that size. Other software can and is worth trying out. 1 Quote Link to comment https://forums.atariage.com/topic/274832-unocart-2600-a-diy-sd-multi-cart-for-the-2600/page/13/#findComment-4174038 Share on other sites More sharing options...

Well then there's the Bad Apple Demo (512kbytes), which HArmony Encore is technically capable of running if only Batari would update the firmware to support it. I imagine it would take a while to flash though. Is there any plans to offer a firmware update to the UnoCart 2600 so that 32GB to 2TB SDXC cards can natively be supported using the exFAT file system? You can "force format" a FAT32 partition to XDHC cards (using Linux, Mac, Windows command line, or third party format utilities), up to a 2Tb absolute partition limit. File sizes are still limited to 4Gbytes or less however. Let's not get carried away now. I doubt we will see "Megabyte and up" sized Atari 2600 games (much less Gigabyte sized) any time soon.

HDTV1080P Posted December 10, 2018 Share Posted December 10, 2018 Doing some more comparisons, the Harmony Encore has a USB port, USB support chip, a separate 512k ram chip, and a 1MB eeprom chip. Because of the extra hardware, the prices are higher on the Harmony Encore. In addition, the UNOCART for the 2600 does not support DPC+ or CDF bank switching schemes. To make the Harmony Encore cheaper in price then those extra chips would need to be removed. But then the product would no longer be a Harmony Encore product since it would have less features.

DPC+: The UnoCart-2600 should be able to emulate every cartridge released during the commercial life of the 2600. Newer homebrew titles should also be compatible with the UnoCart-2600, unless they use the DPC+ co-processor features specific to the Harmony/Melody cartridge. Note that the DPC support on the cartridge is not complete but it is sufficient to play Pitfall II. Further development is , of course, always on going. As for the other things, okay. Not sure what the point is, though. The Harmony Encore is a nice product. The UNO is a nice product. It doesn't need a USB port.

ZackAttack Posted December 10, 2018 Share Posted December 10, 2018 In addition, the UNOCART for the 2600 does not support DPC+ or CDF bank switching schemes. The UnoCart has support for ACE which is another scheme that allows game code to be offloaded to the ARM core. DPC+ and CDF are currently capped at 32kb rom and 8kb ram. ACE supports 448kb of rom and 192kb ram. On the flip side there are many quality homebrews which have already been released for DPC+ and CDF as well as some excellent documentation for developers. ACE is still largely undocumented and there is currently only a single game in development for it. I'd recommend getting both carts if you can afford it. 1 Quote Link to comment https://forums.atariage.com/topic/274832-unocart-2600-a-diy-sd-multi-cart-for-the-2600/page/13/#findComment-4174368 Share on other sites More sharing options...

+-^CrossBow^- Posted December 11, 2018 Share Posted December 11, 2018 SD cards 16MB to 2GB that use FAT are out of production, however SDHC cards that use FAT32 between 2GB to 32GB are in production for now. There is a possibility that in the years to come SDXC cards between 32GB to 2TB might be the only option in retail stores. SDXC cards are native exFAT and some do not work correctly when trying to format them as FAT32. In the ideal world all SD cartridges on the market should support exFAT so that SDXC cards can be used in the native file format. Well, I just know that I've been able to use SDXC cards using SD Formatter I believe it is called for sometime now to force them into a Fat32 structure and at least with my Saturn RHEA (That only supports up to 16gb officially) it works just fine and I've seen videos and spoke with people who have gotten 128gb cards to work in that thing by formatting the cards to Fat32. Now I pretty much tend to only use Sandisk SD cards. No real reason as to why other than they are usually the cheapest brand that I've never had issues with when purchasing an SD card. So I guess it is very much YMMV. Still it can't hurt to try and I might just need to see if I can test that with my UNO and Harmony. That is another solution by the way...save up and get both flash carts. If you can only have one for now, then I would say the UNO will serve 90+ % of most enthusiasts needs and so I would start there and then look at getting the Harmony encore later. I don't have an encore and only have the original 2010 release of the Harmony but I've never felt with either cart that I can't do what I want or needed with them.
