[Python] A memo to operate ROM created by GBDK with PyBoy
It is a memo to operate ROM created by GBDK with PyBoy. This implementation is published in the following repository. https://github.com/Kazuhito00/pyboy-gbdk-examples
What is PyBoy
A Game Boy emulator written in Python. It seems that it is developing not just an emulator but also a platform for reinforcement learning. https://github.com/Baekalfen/PyBoy
What is GBDK
Abbreviation for GameBoy Developers Kit, freeware that allows you to develop Game Boy software in C or assembly language. http://gbdk.sourceforge.net/
Installation GBDK
- Download the GBDK main unit from the link below
https://sourceforge.net/projects/gbdk/files/gbdk/
In this sample, the Windows version ([gbdk-2.95-win32.zip](https: /) /sourceforge.net/projects/gbdk/files/gbdk-win32/2.95/gbdk-2.95-win32.zip/download)) is used. - Unzip to any folder such as "C: \ gbdk"
- Add "C: \ gbdk \ bin" to the system environment variable of Windows
* If you decompress other than "C: \ gbdk", you need to change the path according to the answer location.
PyBoy
- Install SDL2
Ubuntu： sudo apt install libsdl2-dev
Fedora： sudo dnf install SDL2-devel
macOS： brew install sdl2
Windows： (New-Object Net.WebClient).DownloadFile('https://www.libsdl.org/release/SDL2-devel-2.0.10-VC.zip', 'SDL2-devel-2.0.10-VC.zip')
： Expand-Archive -Force 'SDL2-devel-2.0.10-VC.zip' C:\SDL2\
： setx PYSDL2_DLL_PATH C:\SDL2\SDL2-2.0.10\lib\x64
： setx PATH "%PATH%;C:\SDL2\SDL2-2.0.10\lib\x64" - Install PyBoy with pip
python3 -m pip install --upgrade pip
python3 -m pip install pyboy
- For details, refer to the official Installation.
Hello World You can create Hello Work with printf ().
hello_world.c
#include <stdio.h>
#include <gb/gb.h>
#include <gb/console.h>
int main(void)
{
gotoxy(0, 0); //Specify drawing coordinates
printf("Hello World\n");
}
Compiled with GBDK's LCC compiler.
c:\gbdk\bin\lcc -Wa-l -Wl-m -Wl-j -DUSE_SFR_FOR_REG -c -o hello_world.o hello_world.c
c:\gbdk\bin\lcc -Wa-l -Wl-m -Wl-j -DUSE_SFR_FOR_REG -Wl-yt2 -Wl-yo4 -Wl-ya4 -o hello_world.gb hello_world.o
Launch with PyBoy
from pyboy import PyBoy
#Start PyBoy
color_palette = [0xd6e895, 0xacc04c, 0x527d3e, 0x264a2e] #Game Boy-like color palette specification
pyboy = PyBoy('hello_world.gb', color_palette=color_palette)
while not pyboy.tick():
pass
Success if the following window appears.
that's all.
