New games for MMBasic are not always compatible with the UF2 MMBasic releases for PicoGamer and GameMite(5.08 for Game*Mite).

It doesn't look like there are any new UF2 images for the handhelds on the horizon right now.
How do I manually update to the new version, V6.04, so that the GameMite still works?
Will the games from the UF2 image still run? I'm guessing I'll have to back up the settings/options via the terminal and copy the data from drive A: to B: to save them.
How compatible is the GameMite with the PicoGamer, anyway?

Greetings,
Peter

I'm not sure that there is any compatibility between the GameMite with the PicoGamer at all. The two systems were developed independently of each other AFAIK. I don't have a PicoGamer so I can't test.

All,

Pico Gamer and Game*Mite are 99% compatible.
The only difference is that Pico Gamer uses 4MB/16MB flash and Game*Mite has 2MB (RP2040 pico 1).

All programs from Pico Gamer run on Game*Mite. All games from Game*Mite run on Pico Gamer. Both platforms are released with MMBasic V5.8.0

Pico Gamer : Geoff only released 2 uf2 images to program the pico (4MB and 16MB).
Game*Mite : Tom released 1 uf2 image (2MB) and a set of tools (install-a.bas) to create a Game*Mite with 'any' MMBasic version.

This tool was adapted and used by me to create a new Game*Mite uf2 image based on MMBasic 6.3.0. Together with 'patched' games and new games. The games needed patching since there are significant differences between MMBasic 5.8.0 and MMBasic 6.3.0 (and now 6.4.0).

The MMbasic 6.3.0 uf2 file for Game*Mite is a fusion of Pico Gamer and Game*Mite (it uses Geoff's menu system, but still has Tom's file browser and an app).

Also important to note is that Peter created a RP2040MIN version of MMBasic, that has roughly 200kbyte larger A:/ drive, so more games can be stored. At cost of loosing several software functions (turtle/structs/GUI/etc..). These where not used by classic Game*Mite games anyway. This RP2040MIN version was the basis for the Game*Mite 60300 uf2 file.

P.S. There are few Game*Mite's equipped with pico2 (RP2350) boards. There is also a uf2 file for these with MMbasic 6.3.0. To my knowledge there is no Pico Gamer with RP2350 board.

P.P.S. I think you can use Tom's install-a.bas to create your own Pico Gamer with MMBasic 6.4.0. If I had a 2040 board with 4MB and 16MB flash, I could do it for you. It is relatively easy.
