This is a fork of the Genesis Plus GX emulator (https://github.com/ekeeke/Genesis-Plus-GX) that is meant to run classic Sonic games (and possibly other titles, with ROM modifications) in 16:9 widescreen. Specifically, it's meant to run with this hack of Sonic 2.
This project has strayed pretty far from base repository. It has a complete restructuring of the file layout, only supports building standalone emulators (with a completely rewritten makefile), has custom backends for input, sound, and rendering, and has a plethora of new features. Those include:
- Widescreen support
- Support for OGG music (custom Sonic 2 mod only)
- Multi-system multiplayer (to avoid dealing with the weird splitscreen VDP mode)
- Compilation for strange platforms, including
- Emscripten
- Nintendo Switch
- JSON configuration
Compilation is done with the GNU Make system under msys2. You'll need to install some dependencies:
pacman -Syu # Re-run this until no new packages are installed
pacman -S git base-devel
pacman -S mingw-w64-x86_64-binutils mingw-w64-x86_64-gcc mingw-w64-x86_64-SDL2 mingw-w64-x86_64-SDL2_image mingw-w64-x86_64-SDL2_mixer mingw-w64-x86_64-jansson
pacman -S mingw-w64-i686-binutils mingw-w64-i686-gcc mingw-w64-i686-SDL2 mingw-w64-i686-SDL2_image mingw-w64-i686-SDL2_mixer mingw-w64-i686-jansson # Optional
Once you've got them, it's pretty simple to compile:
git clone --recurse-submodules https://github.com/heyjoeway/Genesis-Plus-GX
cd Genesis-Plus-GX
make
Executable should end up at ./bin/Windows/gen.exe.
(need to finish this section)
You'll need to set up an Emscripten development environment. Once you've got it ready:
git clone --recurse-submodules https://github.com/heyjoeway/Genesis-Plus-GX
cd Genesis-Plus-GX
emmake make
This will output files at ./bin/Emscripten. You can serve these files locally to test them. Additionally, copy the files from ./emscripten to the output folder if you want a more refined UI.
