Need info setting up a new UNO cart SD card base directory

[ACML]

Does the UNO cart need certain files in the base directory like a SIO2SD or Sdrive?  Can't seem to find them.  Are they the same as the Ultimate Cart?  I'm sure there is a thread on AA somewhere that covers this, but I'm having trouble finding it.

@ACMLI took this from the Brewing academy website:https://thebrewingacademy.com/products/atari-xl-xe-uno-cart?variant=16644272652388

 

I don't think it does require files in the root directory to run but does appear to have some system requirements as detailed below. Are the A8's you are trying to the cart on meeting the requirements?

The UnoCart is an Atari cartridge emulator (CAR/ROM) & XEX/ATR file launcher. It supports files up to 128k in size. Want an Ultimate, but don’t want to spend the money for all of the bells & whistles? The UNO Cart is the way to go.  

Not sure you have the files?  Want a collection that is ready to run out of the box?  Consider purchasing our 8gb microSD card for the TBA UNO-A8 cartridge!

NOTE:  The UNO-A8 is an amazing piece of hardware, but It will NOT work in a 400 or an 800.  It will NOT run 8mb AtariMax files.  It is also somewhat wonky with modified machines (i.e., containing Ultimate 1M upgrades without the latest FJC firmware)

The creator of the UNO-A8 Cart, Robin Edwards, has been paid a royalty for every cartridge sold. 

 

 

Difference between the UNO-A8 and the Ultimate-A8

 

Ultimate-A8 ($95 and up)

This is a Full Sized SD-based flash cart that will load a variety of ROM, CAR, and XEX files from a menu.  It has a very wide range of uses and will work on ANY Atari 8-bit machine (400/8008600XL/800XL/1200XL/XEGS/65XE/800XE/130XE and, if you have them, a 1400XL or 1450XLD!)

Assuming that the machine you are putting the Ultimate cart into has the RAM to run the program, the Ultimate cart will run it.  I have yet to come across an XEX or CAR or ROM file it could not load.  Put away your stacks of AtariMAX carts—you can put all of those files on to one SD card!

UNO-A8 ($55 and up)

The UnoCart is an Atari cartridge emulator and XEX file launcher. It supports files up to 128k in size. If your machine has 64k or more, it will run ATR (disk image) files. Important note – many ATRs will run correctly from the UnoCart. However, any programs that attempt to use the RAM under OS will not work, nor will any software that does not use the standard OS SIO calls.

 tl:dr

Ultimate:  runs any CAR/ROM/XEX file you can find so long as your computer has the RAM to support it. Runs on any machine modified, stock, 400/800/XL/XE/1088

UNO-A8: runs CAR/XEX files less than or equal to 128k in size.  Will run basic ATR files.  Only operates on an XL/XE/1088.

BOTH: You can use any size uSD or SD card with either cartridge.  They must be formatted FAT32.  We recommend SanDisk name brand cards.

@Beeblebrox:  Thanks for the reply.  Isn't there some OS type file that has to be in the root directory so it can boot ATR files?  Also, is the menu built into the firmware unlike SIO2SD?

I did find a thread that said that UNO_OS.ROM was only needed in the root directory for version 1.1 firmware and that it was built into version 1.2 firmware.  Can anyone confirm this?

Yes, mentioned in the manual here

Uno cart supports "some" atr files. So make sure whatever you are trying is compatible
