An attempted port of https://wabbit.codeplex.com ! Based on the emulator frame created by @xhp-creations. Original readme below.
Added GX2 Graphics, Sound Support, and Super CHIP-8 Support

rw-r-r_0644 version located here: https://github.com/rw-r-r-0644/CHIP8-Emulator-WiiU
The code could be trimmed down some, as this was patched together into HBL code and some code may not be needed.
CHIP-8/SCHIP-8 GX2 Emulator by brienj
I updated the CHIP-8 Emulator made by rw-r-r_0644 to use GX2 graphics, include the buzzer, and support the Super CHIP-8 interpreter.
Setup: Put the CHIP8.elf file in the sd:/wiiu/apps/CHIP8/ folder of your SD card. Put all of your CHIP-8/SCHIP-8 roms in the sd:/roms/CHIP8/ folder of the SD card with the .ch8 extension. Sub-folders are acceptable, but not needed.
Instructions: Load a ROM and press the Play button. If you select the play button with a WiiMote, that WiiMote will be used as the controller, with sideways orientation. The A and B buttons will be swapped with the 1 and 2 buttons, and the X and Y buttons will be swapped with the A and B buttons, if you play with a WiiMote. Once a game is started the Play button becomes a Pause button. Selecting the Config button will open up the controller configuration. Select a controller button on the screen and then select the button number you wish to assign it to. Pressing the Save Config button on the configuration screen will save a 16 byte config file in the same directory with the ROM. Each config file is for each individual ROM, so each ROM can each have a different configuration. The Left-Stick on the gamepad emulates the D-PAD, and the Right-Stick on the gamepad emulates the A, B, X, and Y buttons. This allows you to easily play two player pong on the gamepad using the sticks.
Planned to be added: CHIP-8E, CHIP-8X instructions Display folder name on selection buttons
