Ship #1

This is OctoPy
A chip-8 emulator fully written in python that I made while waiting for one of my other projects to finish rating(IT DOESNT EVEN HAVE ONE, ITS BEEN A WEEK, SOMEONE HALP).
This project was my first emulator so I am proud to present it. It features a CPU with all of the chip-8s instructions programmed into it. It also has a pygame GUI interface, where you can choose ROMS, test the emulator, and even use your own ROMs(make sure they are for the chip8, this isnt a SCHIP or XOChip). This project had its own fair share of issues, such as the FX0A opcode just freezing the emulator entirely, or when games tried to play sound, your eardrums explode. I fixed all of these and finally finished this project. Please leave feedback!

Emulator accuracy improvements

Today I ran multiple test ROMS through my emulator. It passed most of the quirks and flags tests. It had issues with they FX0A instruction though. My previous CPU handled this in a way that the code will stop execution forever, not good. So I fixed that(took way too long) and ran the tests again. I can now say I have made my own emulator!

Dev log #3

Today i finished a boot UI. from here you can choose a game rom and play it. You can also hit esc and return to the menu. I also included test roms just in case someone wants to test the emulator. Emulator doesnt pass some of the tests though so i gotta work on that =(

This is a short project that I hope to finish in a few days…
Today I researched how the Chip-8 works, got some test ROMS, and wrote my CPU.
Next I hope to make a GUI that i can even export to web.
Im not sure what image to put here so here is js a pic of code
