The CHIP-8 Emulator project aims to create a virtual environment allowing software built for the CHIP-8 virtual machine in the 1970s and 1980s to be run on a Wii U console. It was developed by rw-r-r_0644 while following a tutorial here and updated to GX2 graphics + other tweaks by brienj.

Setup

Once the program has been placed on your SD Card (just like any other, in the sd:/wiiu/apps/CHIP8 folder), simply add your ROMs to the sd:/roms/CHIP8/ directory. The ROMs must have the .ch8 extension.

Controls

When the emulator is launched, you will need to select a ROM image. Press Load Rom and select a rom from the list.

The CHIP-8 VM used 16 keys, and each app used them in different ways. Unfortunately, the Wii U GamePad only has 13 mappable buttons, but they can be mapped to any CHIP-8 key. You can edit keys configuration by using the configure button.

At any time during a program, you can simply press the HOME button to quit the program and return to the Homebrew Launcher.
