devlog #1 - writing a emulator

i built this (not so) simple emulator for the CHIP-8 architecture

what’s working:
4kb ram, 16 registers (V0-VF), Index (I) & PC (0x200)
opcodes: clear (00E0), jmp (1NNN), 6XNN and 7XNN (math basically), index (ANNN) and sprites (DXYN)
rendering in ascii (thinking about changing it to sdl2)

todo:
full 35 opcode support
keypad input
(maybe) migrating to SDL2
