TonVH Posted February 23, 2018 Share Posted February 23, 2018 I am wondering what the smart thing to do is. Both have the advantage that I can prepare and put everything on my Mac on a SD-Card. Uno Cart will have (I suppose) the fastest loading times. Uno Cart also does Rom/Bin, Sio2SD not. Both acceptable priced. The 800XL will mainly be used for gaming and I do not plan the "Pokey Divisor 0" upgrade since I do not want to do any soldering. What's best to buy or is there an even better solution for (luxury problem many games, fast loading, ease of handling. Quote Link to comment Share on other sites More sharing options...
JR> Posted February 23, 2018 Share Posted February 23, 2018 SIO2SD is better for disk based software, but for most cartridge based games, or disk based games converted to xex files, I find the UNO easier to use and more convenient. The UNO does work pretty well with ATR files, just not quite as good as SIO2SD. Get both! Quote Link to comment Share on other sites More sharing options...
SS Posted February 23, 2018 Share Posted February 23, 2018 My feeling on this is that if you couple a SIO2SD with an Ultimate Cart then you will pretty much be able to run almost everything ever written for the A8 line. If you are interested in owning only one device, however, I would recommend the UNO Cart. The UNO will run CAR, ROM, and XEX files and can handle about 2/3 of the ATRs that I have thrown its way. I would estimate that the UNO Cart can handle 90-95% of the A8 games out there. I really feel that it is currently the best choice for "one stop shopping". 3 Quote Link to comment Share on other sites More sharing options...

I would agree, with one additional caveat - it does not work with a 400/800. The loader will appear but it will not read the SD card contents. That, and it sits kind of deep in my 1088XEL cartridge tunnel. I’m probably going to get an Ultimate Cart at some point this year did that reason alone.

gozar Posted February 23, 2018 Share Posted February 23, 2018 I'd vote for the Unocart and build an SIO2PC-USB. RespeQT works really well, and you can build one for under $10. I use an old IBM Thinkpad for my Atari server. Quote Link to comment Share on other sites More sharing options...
+Philsan Posted February 24, 2018 Share Posted February 24, 2018 With SIO2SD or SIO2PC-USB (very cheap devices) and a memory expanded Atari you can load (slowly) all software. With carts, without memory expansion, you can load (quickly) most of the software (see Topic for newbies for comparison). 1 Quote Link to comment Share on other sites More sharing options...

Well, 125kbps at POKEY divisor 0 is certainly faster than we had for disk cracks of cartridge stuff BITD. 2 Quote Link to comment Share on other sites More sharing options...
Reality Studio Posted February 24, 2018 Share Posted February 24, 2018 I own both the Uno Cart and the SIO2SD, and ultimately I have listed the Uno Cart on ebay. I just had too many issues with ATR's on the Uno Cart, like Ali Baba wouldn't load at all, Goonies loaded but was all glitched, etc whereas I've had great luck with the SIO2SD, most everything seems to work. If you want to see the SIO2SD in action I used it on a live Twitch stream recently and I posted about that elsewhere. I guess if you don't care about ATR's then the Uno Cart will be pretty cool, but for me I want to play as many games live on Twitch as I can so I wanted ATR's to work, hence I've kept the SIO2SD.

SS Posted February 24, 2018 Share Posted February 24, 2018 (edited) The primary feature of the UNO Cart is its perfect replication of all know A8 cartridges in CAR or ROM format. Its secondary function is loading XEX format files directly. ATR support should be seen as more of a "bonus feature" rather than one of its main goals.

_The Doctor__ Posted February 24, 2018 Share Posted February 24, 2018 (edited) That's why I stick with the Ultimate cart for now, it covers all the cart sizes, the uno has less ram... it doesn't do atr's... but there lot's to choose from out there that does...

SS Posted February 24, 2018 Share Posted February 24, 2018 That's why I stick with the Ultimate cart for now ... ... it doesn't do atr's... If someone really, really needs a specific ATR game on their Ultimate Cart there's always the option to make a MaxFlash CAR image of the ATR and then using that on the Ultimate Cart. 3 Quote Link to comment Share on other sites More sharing options...
Zap! Posted March 18, 2018 Share Posted March 18, 2018 I wonder how the Side 3 will compare when its specs are announced... Quote Link to comment Share on other sites More sharing options...
electrotrains Posted March 18, 2018 Share Posted March 18, 2018 Hi, Interesting to see opinions on my creations... I think SS summed it up nicely above - both the UltimateCart and UnoCart are intended to provide 100% accurate emulation of a wide variety of atari cartridges. ATR support in the UnoCart was added just as a bonus - hopefully I made it clear in my forum posts and the manual that it can never work 100% as a substitute for a SIO device. I'm not aware of any cartridge-based solution that can handle all disk based software, so I doubt SIDE3 is going to do any better a job. Even a modified Atari with U1MB+SIDE cannot (as far as I know - correct me if I am wrong!) handle classics such as Alternate Reality. You'll still need a proper SIO device for that. So, in general, I would recommend people should get a SIO2SD first, then a multicart later, if they want to be able to run a wide range of classic software. Also its worth pointing out that (like SIO2SD/SIO2PC) the UnoCart and Ultimate carts are open source - I made them for my own enjoyment, and open-sourced the designs for the benefit of the atari community - so everyone can see how they work, and improve on them. Future cartridges can use the code as a base and build on the work that I (and flashjazzcat) have done. Let's hope that SIDE3 is also open source when it arrives.

flashjazzcat Posted March 18, 2018 Share Posted March 18, 2018 (edited) Naturally any ATR mounting solution which relies on a) a PBI aware OS (which excludes the 800 OS) and b) usage of standard OS SIO calls for sector transfers (which excludes anything which uses XBIOS, for example) is not going to work with 100 per cent of titles, although in my experience the approach works in at least 90 per cent of cases. Meanwhile, any ATR solution which relies on a RAM-based, patched copy of the OS is empirically the least stable solution and arguably lower on the compatibility scale (since any software which writes to PORTB without carefully maintaining the status of bit 0 will break the ATR handling). Ironically, the only thing preventing the UNO cart from being arguably the most powerful and compatible cartridge based solution in existence is the reluctance to make it work in unison with U1MB. Which is to say: it's the software. This is why SIDE3 is a valid and opportune response to the UNO cart. Since the UNO hardware is essentially a flexible, powerful blank canvas, had it included from the outset a SIDE2 IDE emulation layer and an externally accessible API for mounting cartridge images, it would have pretty much wiped the floor with everything else on the market when paired with U1MB. SD card based PBI ATR handling and APT hard disk, and accurate emulation of the vast majority of banked cartridge schemes. Want to use BASIC XE with your 32MB APT hard disk on a 1200XL with U1MB installed? No problem. Want to use MAC/65 with an ATR? No problem. Right now, the nearest one can get to this Utopia is by running a UNO Cart on a 1088XEL with an XEL-CF. I'm told that one can mount ATRs and then launch cartridge images, and aside from the unfortunate fact that the two operations cannot be carried out from the same loader (which is entirely achievable using a different UNO firmware and some modifications to the U1MB firmware), everything works quite well. This kind of setup is in fact so appealing that I have long harboured the desire to create an alternative UNO firmware, primarily for my own use, which turns the cartridge into an SD-card based SIDE2 with cartridge emulation capabilities. What prevents me is a lack of time, lack of experience and lack of familiarity writing firmware for modern MCUs. The vision is perfectly clear, however. I even realised that the FATFS library could be completely jettisoned if the MCU's RAM were exposed to the 6502, which is perfectly capable of loading the cartridge image data onto the physical cartridge. So, as virtuous as open-sourcing projects is perceived to be, I have no expectation that SIDE3 will be open-source, not least because it's supposedly going to be powered by my closed-source XEX loader. But aside from the lack of an RTC (redundant when U1MB is present) and mode switch (which can be worked around in software), the open-source equivalent of SIDE3 is already sitting in our hands. It's called the UNO cart. As for open-sourcing in general, it's clear that any user who isn't actually intending to contribute code to a project just wants the stuff to work and doesn't care whether it's open-source or not. The number one complaint I receive about U1MB and SIDE2 is that neither device is capable of emulating banked cartridges (aside from SDX and anything else expressly aimed at the existing banking scheme). SIDE3 will - if sanely designed - address that shortcoming, and will thus be arguably the most capable cartridge solution available (regardless of whether any effort is made to support ATRs without U1MB's presence and involvement). This isn't the first time this approximate sequence of events has occurred. SIDE1 was vastly superior to the MYIDE/FLASH but lacked card hot-swapping, etc. MYIDE2 added card hot swapping, limited cartridge emulation, and other stuff, but completely shut itself out of the emerging standards developed for and by new projects of the time (APT, U1MB's versatile PBI HDD/ATR handler, etc). SIDE2 countered by adding hot-swapping and other improvements. but lacked cartridge emulation. UNO came out and made the best fist of cartridge emulation but can't act as a HDD/ATR host for U1MB. In almost every scenario I have observed or participated in over the past decade, striving for integration between one popular upgrade/device and the other improved the user experience, while ignoring emerging standards and deciding to "do it my way" ended up requiring the user to purchase multiple devices to accomplish all the required tasks because no single or compound solution does everything the user wants. I suppose this is the way the free market works, of course. If SIDE2 had possessed the cartridge emulation capabilities seen on the Ultimate and Uno carts, there would be little reason for the user to subsequently purchase anything else (although the move from CF to SD card is inevitable and welcome).

Zap! Posted March 24, 2018 Share Posted March 24, 2018 I have an Atari 800XL owner with 1050 drive. From what I understand, nothing does everything (Side 3 might, but it's still unknown). So in everyone's opinion what would be the best combination that will run everything (or nearly everything?) Should I order an UNO and SIO2SD? If I do that combo, what would be my limits over spending a little more money on the SIDE 2/Ultimate Cart instead of the UNO? So basically what I'm asking is that I want to limit my buying to two things. What combination will give me the most options? Quote Link to comment Share on other sites More sharing options...
SS Posted March 24, 2018 Share Posted March 24, 2018 An Ultimate Cart and SIO2SD combo will let you run almost everything, baring possible PAL/NTSC and memory issues. 2 Quote Link to comment Share on other sites More sharing options...
+Philsan Posted March 25, 2018 Share Posted March 25, 2018 A 1MB memory expanded Atari + SIO2SD loads everything. If you add a multicart you can load almost all games fastly. In my opinion Ultimate cart is a good solution. Check out Topic for newbies comparison table and Multicart section. 1 Quote Link to comment Share on other sites More sharing options...

dancroteau41@gmail.com Posted September 25, 2022 Share Posted September 25, 2022 does anyone have a list of the atr games / files the uno cart won't run???? would be a big help!!!! just think on loading of files to your uno cart that just don't run,the days when things run smoothly. Any if so please direct me, I in return will reciprocate by helping someone else!!!! Quote Link to comment Share on other sites More sharing options...
ACML Posted February 22, 2023 Share Posted February 22, 2023 (edited) I've just recently acquired an Ultimate Cart and to this long time Atari 8-bit user, it is amazing. I have no idea why I haven't discovered cartridge emulation prior to this. The fact that it can emulated any cartridge is a game changer in my thinking. What ever you need MAC/65, Action!, Microsoft BASIC II, Editor Assembler, etc., you got it! Then there is the ability to run XEX files, hit the reset button on the cartridge and not have to cold cycle the machine to change games. I then acquired an UNO Cart. Much more economical, does 99% or what I need the Ultimate Cart to do, plus loads ATRs. My all time favorite data interface remains the SIO2SD. It's just so darn reliable in how it operates and the flexibility. As others have already mentioned on this post, you need both and you will want for nothing. Excellent pairing! Hats off the the developers of the Ultimate/UNO Cart and SIO2SD. I realize the AVG Cart is the current rage, but I'm a 1200XL guy and the current case offerings are not 1200XL friendly. There is an aftermarket case, but you have to pay another $35 with shipping for a Cart that already costs near $100 shipped. This is where the UNO Cart shines. It's half the price of an AVG and is already 1200XL friendly. Pair it up with a SIO2SD and you can do pretty much anything. Still amazed at how long it took me to catch on to the Cart emulation hardware. I just owned all the OEM Carts and didn't realize how convenient the Ultimate/UNO option was. Another reason I'm in awe of the UNO Cart is that when using my trusty SIO2SD, I have to keep resetting the menu on the LCD display and cold cycle the machine to change games. With the UNO Cart, I can run through 10 or 20 games in a session and never have to cold cycle the hardware.

Beeblebrox Posted February 22, 2023 Share Posted February 22, 2023 Sounds a good option for many and especially for your 1200XL setup. Reason I opted not to go down the uno route was that it can only mount car files up to 128k, and it has no file management functionality. I love the fact there is a good range of these carts out there for the A8's to suit most user's needs. Quote Link to comment Share on other sites More sharing options...
_The Doctor__ Posted February 22, 2023 Share Posted February 22, 2023 (edited) The only UNO plus I saw was the co processing/accelerating ability. That positive made me look. That's the only thing I'd like to see on other carts. As the 3D supercharging carts of old should or could be emulated as well. The negs kept me from getting one.

mimo Posted February 22, 2023 Share Posted February 22, 2023 I just took my AVG cart out of it's case and use in in my 1200xl, 400 and 800. Lack of a case really doesn't worry me Quote Link to comment Share on other sites More sharing options...
magnusfalkirk Posted February 22, 2023 Share Posted February 22, 2023 Just to add my 2 cents. I have the Side 3.1 and an S-Drive Max. With that combination there doesn't seem to be anything I can't run. Been thinking about adding the U1MB, which if I understand things correctly, will make my S-Drive Max obsolete, since the Side 3.1/U1MB combo will allow me to run all Atari software from the Side 3.1.

E474 Posted February 22, 2023 Share Posted February 22, 2023 Hi, I got ARM code up and running on the UnoCart, I had problems with accessing the FAT file system (the ARM chip crashed), and had to put development aside as I had to deal with other projects/matters. The repo is here, if anyone is interested: https://github.com/e474/UnoCart-Develop Also, the UnoCart polls the 8-bits address/data lines, @electrotrainswrote that he tried to implement interrupt based handling, but couldn't get it to work, but if it did work, it would be a much more interesting approach (more ARM cycles for co-processing). You need an STM-link USB dongle if you want to change the firmware, but I got one from eBay for about 3 GBP, pre-pandemic (IIRC). Getting hold of STM32 MCUs is a bit difficult at the moment, though. It is a project I want to get back in to, but I don't have much free time at the moment. One thing I was wondering about was adding in UnoCart detection/support for the ROM in the Compiling a new Atari OS: That should, I hope mean better UnoCart support for ATRs as it wouldn't be using a SoftOS, but a ROM image, so the RAM under the OS wouldn't be used. Hope this helps! Quote Link to comment Share on other sites More sharing options...
