A8PicoCart - UnoCart on a Raspberry Pi Pico
Hi All,
I got a Raspberry pi pico a few weeks ago to have a play with and forgot about it. Then, after noticing a post here, I realised I couldn't resist having a go at using it to make a multicart for the Atari 8-bit. A couple of PCB revisions later, I'm pretty much done, and proud to announce the A8PicoCart!
Unfortunately the official Pico board hasn't got quite enough pins to make a proper multicart - you can emulate 8k and 16k carts, but that's about it. However I dis
Okay, I've had a filddle with this, and rather than modify the existing firmware, please find attached a single cart version of the firmware.
If you put a file named "AUTORUN.CAR" or "AUTORUN.ROM" in the root directory, it will run automatically on power up. Identification rules for ROMs as described in the manual (standard 8K & 16K or XEGs is assumed depending on the file size). If you want a different type (e.g. 128K AtariMax) - use a CAR file.
It will leave any oth
