I really wish there was hardware of a similar form factor that ran Pico 8. The Pocket CHIP is a start, but it's a more general-purpose machine with Pico 8 support.
I was just thinking that this is tantalizingly similar to, but not quite the same as, PICO-8 on on a Pocket CHIP. It seems a shame to split such an interesting market like this. Pocket CHIP has the advantage of letting you code right on the device, of course, but how much value does that really have? Even on PC, some devs prefer to use a separate text editor rather than deal with text at PICO-8's resolution, and the dinky keyboard doesn't help.
Pico 8 is based on Lua, so a relatively powerful CPU and lots of RAM are needed to run it.
Hmm, you can get eLua which runs on microcontrollers, I wonder how you would handle the graphics though.
Should be getting the Pocket CHIP in a couple of weeks. Already developing a game for it. The Pico-8 flavor of Lua is a dream to program for. It hasn't been this easy to develop games since Flash for me.
