'''Rustation''' is an open-source [[PlayStation emulators|PlayStation emulator]] that doesn't require a plugin-based system. It's written in the Rust programming language and has a [[libretro]] core.
'''Rustation''' is an open-source [[PlayStation emulators|PlayStation emulator]] that doesn't require a plugin-based system.
The first commit for Rustation was made on [https://github.com/simias/rustation/commit/017db106eaf9b8268eb58a24612da948f4b8c2fc February 17, 2015], and many commits have since been added over the next two years. However, the last commit was made in [https://github.com/simias/rustation/commits/master September 2017] and was never followed up; the same is also true of the libretro core. The libretro team, meanwhile, used the work done in Rustation to create the [[Mednafen|Beetle PSX]] ''HW'' core, in which an OpenGL 3.3 renderer is used instead of the previous software renderer.<ref name="libretro-Rustation">{{cite web|url=https://www.phoronix.com/scan.php?page=news_item&px=PSX-OpenGL-Experimental|title=PlayStation Emulator Gets Experimental OpenGL Renderer|publisher=Phoronix|author=Michael Larabel|accessdate=2018-12-14|date=31 May 2016}}</ref> That core is said to be one of the first PlayStation emulators to use modern OpenGL, as it differs from the fixed-function OpenGL used in older OpenGL-based emulator plugins.
The original repository only contains the source code for the core of the emulator. The OpenGL renderer and the libretro interface is in the rustation-libretro repository. Game performance is poor; only a few games can boot.
These things are either fully or partially implemented:
* Basic GTE support (ported from mednafen PSX)
* Instruction cache
* Interrupts
* Basic GPU (no semi-transparency or mask bit emulation)
* Timers (incomplete)
* Debugger
* CDROM controller (missing many commands)
* Gamepad controller (only digital pad for now)
<u>'''To-do list:'''</u>
* Many things in the GPU
* MDEC (Probably for movie playback. [[Avocado]] is in the midst of implementing this one)
* Memory card
* CPU pipeline emulation
* More accurate timings
* Many, many other things...
