I noticed Gamebuino Meta library is visible on github https://github.com/Rodot/Gamebuino-Meta
I had a quick peek into the library. Its nicely structured, should be no big issues in porting when the time comes - features like the flashing neopixels can simply be bypassed. And since Pokitto is mbed (and not Arduino) we can’t make games binary compatible (only source compatible). In any case my first analysis is that Pokitto / Gamebuino Meta games will be very close to each other, although Pokitto has a little bit more resolution. If we get a lot more games activity in this way, then its a win-win for both platforms.
Maybe the library is not fully shown (I suspect so) but the graphics part is pretty close to the normal Adafruit TFT library, nothing too fancy. Sound is almost the same structure as in Gamebuino original.
Its an interesting bunch of code you can go and check it out yourself.
