These are a dime a dozen, but I thought I'd have a go too just for funses. I cobbled this together in about 4 days.
A selection of games can be found
here and the source
here. Requires SFML and SFGUI. The CMake file is tested on linux and there is a VS2015 project for windows. I may possibly add MegaCHIP support, but for now I'm bored and am going to move on
EDIT: I've also written a
short blog post about the bytecode format it uses, for those interested.
