Next feature for the PM2040 flash cart for the Pokemon mini coming: Backup and restore of the handheld's internal EEPROM memory (used for gamesaves). The savefiles can be stored and restored to/from the flash cart. USB drive mode planned as well.

Bluesky exclusive

The current version is at the attached repo. GB ROMs can be injected via a simple browser-based patcher.

GB mini - Game Boy games on the Pokemon mini. The emulator is running on the PM2040 flash cart. As the PM has built-in rumble, GB rumble games (like Pokemon Pinball) use the PM's rumble. Save games supported as well. Next step audio emulation.

Pokemon Red running on a Pokemon mini 🙃

I pushed the code for this to its own branch. But it's very much not polished (and no sound or rumble), mostly just to put it somewhere for now.

Beside the processing power of the RP2040 (essentially both cores are available, since the cart serving is completely done via PIO & DMA), one advantage could be easier programming with modern tools.

I played a bit more with the idea of using the RP2040 on the PM2040 flash cart to also fully run "games", whereas the Pokemon mini merely pulls framebuffer data and sends button states to the cart.
I created a small Pong-like game as a PoC.

Flex PCB seems to fit :), now waiting for the FFC connector.

Dead chuffed with this (2nd itteration, and delivered this morning). It's a Pokemon Mini flash cart. I didn't solve the PIO logic (though had planned, but was beaten to the punch), but I did do the design to fit an entire Rasberry Pico into the cartridge form factor, including the USB port.

To save some space, I made a vertical stand for the 3DO FZ-10 model. Mainly as a display stand, but I guess it also should be fine for units with an internal ODE.
Note: It sits on the AV expansion port, so that port is not accessible.

I played a bit more with the "2 in 1" firmware for my RP2040-based flash cart for the Pokemon mini and now added it to the GitHub repo. ROMs can be easily injected via an online tool into a base FW and then transferred via USB-C on the flash cart.
