Emulator that emulates Chip-8 and SuperChip completely. It can emulate all of the games, official and unofficial. MegaChip support has been left out due to lack of documentation on the subject.
I have always been very interested in emulators and it was announced that Chip-8 is a great platform to learn the inner workings behind it. After creating this emulator I definitely learned a lot about how the CPU (registers, op-codes, state-flags, stack and program execution), RAM (overflowing, operations between CPU/RAM, dynamic ASM generation) and GPU (pixel plotting, collision feedback, sprites) work.
The emulator ships with a large game package. Our favorite game is: “Ant – In Search of Coke [Erin S. Catto]“, an amazing sidescroller.

- Faster execution and no longer requires Ogre Engine.
- No more external resource files, everything is embedded into the final executable.
- Added a start-up “BIOS” game.
- Now supports scaling the window to any size.
Version 2011 – 2015
- Now utilizes various inline x86 assembly instead of manual carry flag detection and various speed improvements.
- No longer resets game speed when the game is reset.
- Fixed rendering artifacts and inaccurate collision detection.
- Fixed SHL,1 (shift register left by 1) that set Register F to the least significant bit instead of the most significant bit.
- Small GUI changes.
