Is it possible to get the p8 file anywhere for this? That way I could run it in retroarch?
Sorry, I don't think it's possible, unless you can somehow unpack the game file itself and pick it apart.
I lost all the Pico games I had made to a HDD failure not too long after I published this one and naturally I was dumb enough to compile the only game that survived online in a way where you can't view the source code.
