CPBoy
CPBoy is a work in progress DMG GameBoy emulator for the fx-CP400. It based on the Peanut-GB emulator by deltabeard.
Since the CAS has a rather slow processor, a high speed emulator core is mandatory to run emulation at an acceptable speed. Unfortunately, the accuracy of the emulation suffers a bit, which causes some games to be unplayable or have bugs.
Getting Started
You will need to have the Hollyhock-2 CFW installed. After that just copy the most recent CPBoy.hkk from the releases tab into the root directory of your calculator.
To load your Gameboy ROM, create a directory named "roms" and copy it to that to "usr/CPBoy" directory on your calculator. (if the folders "usr" and "usr/CPBoy" do not exist, create them).
The program should automatically detect the roms and create a selection menu.
Controls
| Calculator key | GB key |
|---|---|
| EXE | A |
| + | B |
| SHIFT | SELECT |
| CLEAR | START |
| UP | UP |
| DOWN | DOWN |
| LEFT | LEFT |
| RIGHT | RIGHT |
MISC:
- (-): Exit emulator
- KEYBOARD: Toggle frameskipping (When enabled, only render every second frame, which speeds up the emulator a bit but lowers its FPS)
- BACKSPACE: Enable Interlacing (When enabled, only render every second line and switch every frame, which speeds up the emulator a bit but makes visuals worse)
Building
If you want to build the emulator from source you will need the Hollyhock-2 SDK. Then, run ´make´ in your terminal to build it.
