TURBOWARP IS REQUIRED FOR THIS PROJECT https://turbowarp.org/1144248944?fps=60 woooooo yet another emulator from the minecraft dirt block guy, no way In all seriousness, this is my third emulator so far (GB, NES then SMS/GG) and this is the simplest one out of them all. I didn't use GoboScript here, even though this emulates a regular Z80 :D I also use some neat optimizations in the pen renderer, using the previous frame for reducing usage of pen strokes to make the emulation faster. NOTE: This emulator is not the most accurate for now, so if you find any bugs with this emulator you can talk about it in the comments.
