The 2nd Master System/GameGear emulator on scratch, and my first successful emulator attempt aside from chip-8. https://scratch.mit.edu/discuss/topic/856442/ Doesn't run games yet; the CPU interpreter is being reformatted and the VDP STILL doesn't work. O for options 1 to show/hide CPU registers 2 to show/hide PSG registers 3 to show/hide VDP registers Hold 4 and press 5 to step CPU Click the controllers on the menu to remap the buttons. https://turbowarp.org/889057250 recommended. ROM that works: 068278D37F060778D37F069078D37FC30F00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000069F78D37F06FF05CA0000C36D00
Overall completion: ~54% Z80: ~50% SN76489: ~98% VDP: ~12% Currently still reformatting the Z80 from the weird way it was before. As it turns out, I needed FAR more knowledge of computer graphics then I had in order to implement a functioning VDP.
