# SSNES
|
|
|
|
SSNES is a simple frontend for the libsnes library.
|
|
|
|
# libsnes
|
|
|
|
libsnes is the emulator core of bSNES, the most accurate SNES emulator to date, in library form.
|
|
This enables the possibility of custom front-ends for the emulator.
|
|
|
|
# Philosophy
|
|
|
|
SSNES attempts to be very small and lean, while still having all the useful core features expected from an emulator.
|
|
It is close in spirit to suckless' DWM, in that configuring the emulator requires a recompile.
|
|
The configuration is done through editing a C header file.
|
|
C programming skills are not necessary to configure it (no programming involved), but some basic programming experience might be needed.
|
|
|
|
# Dependencies
|
|
|
|
SSNES requires these libraries to build:
|
|
|
|
- GLFW
|
|
- libsamplerate
|
|
|
|
SSNES can utilize these libraries if enabled:
|
|
|
|
- nvidia-cg-toolkit
|
|
|
|
SSNES needs one of these audio driver libraries:
|
|
|
|
- ALSA
|
|
- OSS
|
|
- RoarAudio
|
|
- RSound
|
|
- OpenAL
|
|
|
|
# Configuring
|
|
|
|
SSNES configuring is done through editing <tt>config.h</tt> and <tt>config.mk</tt>.
|
|
The default configs can be found in <tt>config.h.def</tt> and <tt>config.mk.def</tt> respectively.
|
|
Do note that you might have to edit <tt>config.mk</tt> if you edit driver and filter options!
|
|
By default, ALSA audio driver is assumed.
|
|
|
|
Most options in <tt>config.h</tt> should be self-explanatory.
|
|
To configure joypads, start up <tt>jstest /dev/input/js0</tt> to determine which joypad buttons (and axis) to use.
|
|
|
|
# Compiling and installing
|
|
|
|
The good old <tt>make && sudo make install</tt> should do the trick :)

# Filters and Cg shader support
|
|
|
|
This is not strictly not necessary for an emulator, but it can be enabled if desired.
|
|
For best performance, Cg shaders are recommended as they do not eat up valuable CPU time.
|
|
Cg shaders are compiled at run-time, and shaders could be dropped in.
|
|
All shaders share a common interface to pass some essential arguments such as texture size and viewport size. (Common for pixel art scalers)
|
|
Some Cg shaders are included in hqflt/cg/ and could be used as an example.
