achtbit
An 8 bit emulator created on the scratch, including an assembler.
...This system is an experimental 8 bit, 16 color computer, with a processer similar to Z80, that (on my laptop using linux with NO opengl support) achieves up to 1.2 Million instructions per second and 50 Hz. screen refresh rate.
It has a builtin assembler to load assembler programs.
There is a rudimentary rom that implements some basic functions like line input, or a system clock.
Also there is a snake game, (depending on that rom), as a reference and for fun!
Take a look, give me your reply!
When having ideas for better performance, let me know!
