The Ultimate Cart For Atari 8 bit Computers

We will examine and use the Ultimate Cartridge designed for the Atari 8bit line of computers. This cartridge allows you to emulate any 8k, 16k or any other type of cartridge ever created for the Atari computers. It accepts an SD card for placing ROM or CAR files that can be executed at startup thus emulating the original cartridge.

    man. time to get one of these and breakout my Atari 800XL. I loved Archon back in the day, used to play it on my uncle’s C64.

    Does this cart do away with needing to use cassettes to load games that are only on cassette?

    Actually Alley Cat was only released for 8-bit Atari and… IBM PC. There was no C64 version.

    Both BASIC XE and MAC 65 have extension disks which load on bootup.

    Thanks man! I appreciate you left your mistake with the different SD card in the video and not edited it to make you look perfect. This way we can learn from your mistake or we might know what to look for in case we get the same error.

    Interesting! Could you maybe do a video on the Ultimate 1MB upgrade?

    Super expansion card..very nice video..

  11. GORF on March 29, 2021 at 11:24 pm

    You could always burn a ROM…PC boards are cheap AF nowadays. PCB way or JCPL or one of those folks can print 5 for 5. The ultimate however is the best way to go!

    ultimate cart is a really nice Hardware Extension for the XL/XE and a must

    Thanks for your videos on this. I was debating between this, and a different SD solution to hook up to the SIO bus. This convinced me to go with the SIO bus solution at first, as I really want to be able to save files and such.
    This will be a perfect second add on for my 800XL for the ease of using carts, though. I am a big fan of The Brewing Academy – great products!

    Is it possible that you have the max size wrong and actually the FILE SIZE limit of FAT32 is 4GB but you can format larger cards to FAT32 even that 128GB. It is a very common misconception of these kinds of devices that people make. Most of my devices can format up to a 256GB card as FAT32 and work just fine in them. Try that out. You will need a program like https://www.diskgenius.com/ or many others that can force Win to format higher than 32GB cards as FAT32.

    Do you know if it will play modern homebrew files that can be as much as 1mb in size or are we a talking about a physical memory upgrade to the motherboard? Also i’m guessing it can’t handle multi-loader disk based games unless they have been converted to a single xex file.

  16. The Annoyed Mr Floyd on March 29, 2021 at 11:44 pm

    Modern version of the Atari 800 Right Slot SALT cartridge.

    Yeah! I have the MAC65 cartridge! And BASIC XE.

  17. Cw Tbird on March 29, 2021 at 11:45 pm

    this will not work with the 400 and i don’t know about the 800. The 400 requires its cartridge door to be shut to operate and this cartridge is too tall.

  18. Dave Stelljes on March 29, 2021 at 11:47 pm

    Thanks for the informative video. I ordered my Ultimate Cart several days ago and am looking forward to it. I recently got my 800XL out of the attic and now going retro! After 30+ years of being offline- I am ready to bring the A8 into the 21st century. I am lucky that most of my floppies still work. Also- it looks like you have the Hakko FX888D there… great iron!

    What kind of display is that? That screen looks amazing.

  21. GenXGrownUp on March 29, 2021 at 11:53 pm

    That’s just cool. The Atari 8-bit was my first computer love so it’s so neat to see it still getting love in the 21st century. Also, as a fellow content creator, you’ve gotta tell me what model that monitor is — when I first saw your shot of the screen I thought that was a recorded output being composited, but then I realized it was just a standard shot. I’ve never seen a monitor show up so well on video with no washout or glare!

    You stated that UltimateCart is limited to a 4GB card, and this has never been true for me. Even if the docs say that officially, I’ve used 32GB SanDisk Ultra cards with my UltimateCart for the past 18 months and had no issues whatsoever. I think it has more to do with the way the card is formatted. You can’t format a card greater than 32GB as FAT32 by default. It takes a special app to do this. For this reason, any microSD card larger than 32GB typically comes formatted as exFAT, and I think that’s where the problem comes in. I think that format is incompatible with the UltimateCart. As long as your microsSD card is formatted as FAT32, any card up to 32GB should work, and you may be able to use larger cards as long as you’ve gone to the extra step of reformatting them to FAT32.

    Am I correct in assuming that any ROM files will only run on the Ultimate Cart? I have an SD Drive Max but can’t run ROM files from it.

  24. Christophe Germe on March 29, 2021 at 11:59 pm

    Interesting, why did you change the case? I prefer the red but was there another reason?

  25. Vinnie T on March 30, 2021 at 12:01 am

    Thanks for the videos. Can I ask what the monitor you are using?

  26. GamedOut Gamer on March 30, 2021 at 12:02 am

    Good video thank you. AVG Cart is much better though. It emulates all carts as well as the SIDE2+Spartados X with full hard drive read/write support. It also supports ATR (floppy disk images) hot swapping when used with U1MB. Its menu isn’t as pretty though. Cassette emulation is in the works now by use of a cable between AVG and SIO. See the Atariage forums AVG Cart thread. I enjoy your interest expressed here about A8!

    Looks like a quite nice option

  28. edu on March 30, 2021 at 12:06 am

    Thanks man! Great videos. I enjoyed. Looking for technology for my 800XL and this is awesome. Greetings from Buenos Aires. Bye!

  30. Piotr D. Kaczorowski on March 30, 2021 at 12:08 am

    Looking for nice retro tv/monitor… Nice Panasonic TV/monitor.. What is a model?

  31. Magnus Inventum on March 30, 2021 at 12:10 am

    This is fantastic, but there are so many amazing titles that were disk only that do not seem useable here. I think these were Are files. Also titles such as Tarzan and Seven Cities of Gold use more than one disk, which will not work with this. Nevertheless, there seems some great uses for those rare cartridges just as you’ve mentioned.
