A CHIP-8 emulator that works in the UEFI environment without any OS. Works both on real hardware and QEMU.
The repo also contains some popular CHIP-8 roms, located in roms.
You can add your own games there.
The roms are sourced from here.
First run git submodule update --init to pull the required efi headers.
You need to have clang, lld and make installed. Then you can just run make all.
You need to have qemu-system-x86_64 and ovmf installed.
If your distribution does not come with ovmf you need to find a OVMF.fd file online and put it to the repo root.
When you have all the prerequisites ready just run make run.
Run make partition to create the required folder structure.
Then just put the contents of the ./partition folder to your FAT32 formatted pendrive and boot from it.
