# sm64pc
OpenGL adaptation of [n64decomp/sm64](https://github.com/n64decomp/sm64).
Feel free to report bugs and contribute, but remember, there must be **no upload of any copyrighted asset**.
Run `./extract-assets.py --clean && make clean` or `make distclean` to remove ROM-originated content.
## Features
* Native rendering. You can now play SM64 without the need of an emulator.
* Variable aspect ratio and resolution. The game can now correctly render at basically any window size.
* Native xinput controller support. On Linux, DualShock 4 has been confirmed to work plug-and-play.
* True analog camera control is now available on our [testing branch](https://github.com/sm64pc/sm64pc/tree/testing).
## Building
### On Linux
#### 1. Copy baserom(s) for asset extraction
For each version (jp/us/eu) that you want to build an executable for, put an existing ROM at
`./baserom.<version>.z64` for asset extraction.
#### 2. Install build dependencies
The build system has the following package requirements:
* python3 >= 3.6
* libsdl2-dev
* [audiofile](https://audiofile.68k.org/)
* libglew-dev
* git
__Debian / Ubuntu - targeting 32 bits__
```
sudo apt install build-essential git python3 libaudiofile-dev libglew-dev:i386 libsdl2-dev:i386
```
__Debian / Ubuntu - targeting 64 bits__
```
sudo apt install build-essential git python3 libaudiofile-dev libglew-dev libsdl2-dev
```
__Arch Linux__
```
sudo pacman -S base-devel python audiofile sdl2 glew
```
__Void Linux - targeting 64 bits__
```
sudo xbps-install -S base-devel python3 audiofile-devel SDL2-devel glew-devel
```
__Void Linux - targeting 32 bits__
```
sudo xbps-install -S base-devel python3 audiofile-devel-32bit SDL2-devel-32bit glew-devel-32bit
```
#### 3. Build the executable.
Run `make` to build (defaults to `VERSION=us`)
```
make VERSION=jp -j6 # build (J) version with 6 jobs
make VERSION=us WINDOWS_BUILD=1 # builds a (U) Windows executable (under Windows, compiling for Windows under Linux is not supported)
make BETTERCAMERA=0 # builds an executable with the original SM64 camera (no analog/mouse support)
make TARGET_RPI=1 # targets an executable for a Raspberry Pi
```
### On Windows
#### 1. Set up MSYS2, following [this guide](https://github.com/orlp/dev-on-windows/wiki/Installing-GCC--&-MSYS2).
#### 2. Install dependencies
```
pacman -S mingw-w64-i686-glew mingw-w64-x86_64-glew mingw-w64-i686-SDL2 mingw-w64-x86_64-SDL2 python3
```
#### 3. Copy baserom(s) for asset extraction
For each version (jp/us/eu) that you want to build an executable for, put an existing ROM at
`./baserom.<version>.z64` for asset extraction.
#### 4. On MSYS2, navigate to the sm64pc folder and then enter `./tools/audiofile-0.3.6/`. Inside this directory, run
```
autoreconf -i
```
Only leave this directory on step 9.
#### 5. Run the `configure` script
```
PATH=/mingw64/bin:/mingw32/bin:$PATH LIBS=-lstdc++ ./configure --disable-docs
```
#### 6. Run the `make` script
```
PATH=/mingw64/bin:/mingw32/bin:$PATH make
```
#### 7. Create a lib directory in `tools/`
```
mkdir ../lib
```
#### 8. Copy the compiled libaudiofile to `tools/lib/`
```
cp libaudiofile/.libs/libaudiofile.a ../lib/
cp libaudiofile/.libs/libaudiofile.la ../lib/
```
#### 9. Navigate back to `tools/`, then alter the `Makefile` and add `-lstdc++` on the following line
```
tabledesign_CFLAGS := -Wno-uninitialized -laudiofile -lstdc++
```
#### 10. Run `make`
```
PATH=/mingw64/bin:/mingw32/bin:$PATH make
```
#### 11. Navigate back to the sm64pc root directory.
#### 12. Finally, run `make` once more.
(Note that mingw32 and mingw64 have been swapped. This is so you can build the 32bit application successfully.)
```
PATH=/mingw32/bin:/mingw64/bin:$PATH make
```
### For the web
The game can be compiled for web browsers that support WebGL using [Emscripten](https://github.com/emscripten-core). To do so, install [emsdk](https://github.com/emscripten-core/emsdk) and run `make TARGET_WEB=1`.
## Optional enhancements
On the `./enhancements` folder, you'll find several .patch files, which can be applied in the following manner:
```
git apply fps.patch --ignore-whitespace --reject
```
If any rejections occur, you can search for them with `find | grep .rej`.
Try to solve rejections through [wiggle](https://github.com/neilbrown/wiggle).
```
wiggle rejection.rej --replace
```
### Current issues
* Support for the EU version is still experimental.
* There seems to be savedata-related problems on some 64-bits builds.
* Camera controls are also bugged for some.
