retro8 VS Arduboy

So, it sounds like what you're experiencing is just plain old compatibility issues with Retro8, and you should file them as bugs on Retro8's issue page.

I'm guessing you've already seen/tried this? "GitHub - Jakz/retro8: PICO-8 implementation with SDL2/SDL1.2 and RetroArch back-ends" https://github.com/Jakz/retro8

I found Pico-8 when I installed the ADAM distribution on my RG350M. I downloaded a cool curated romset of about 100 PICO-8 games (https://github.com/Jakz/retro8/files/5432890/cartridges.zip)

There are projects for porting the full Pico8 engine to different platforms, but as it is a closed source project the actual process is closer to making an emulator than a port. The main one I know of is Retro8, but there are a lot of others.

a pico8 core is in development though: https://github.com/Jakz/retro8

Too bad we cannot 'pull' or easily convert the 200+ games from Arduboy into the Playdate. The screen looks similar in size.

There’s also Arduboy

I'd suggest something like https://www.arduboy.com/ although I'm not sure anyone has got Rust working well with it.

If you aren't interested in the building part, I suggest the Arduboy

My personal favorite 8-bit gaming machine is the Arduboy. They combine an Atmega 32u4 with a minimum of hardware to create a surprisingly good console.

You can modify and extend it to your hearts content and there's a usable software stack and helpful community grown up around it.

How about the Arduboy? https://www.arduboy.com

You could look into Arduboy- same idea, credit-card sized unit so it's actually playable. It does cost more- but it's been out longer so there's a lot more stuff for it. If you buy the new FX model, it has 200 games preloaded on it. I've got that & the original kickstarter unit, they're actually pretty fun!

It's not supposed to be an emulation console, it's supposed to be a nicer arduboy.
