All of these come with the [[Emulator_Files#Multi-System|RetroArch BIOS pack]] and are correctly named.

'''Mednafen''' (an acronym for '''My Emulator Doesn't Need A Frickin' Excellent Name''', formerly '''Nintencer''') is an open-source, [[Multi-system emulators|multi-system emulator]], driven from the command-line. Many of its cores are ports of other emulators, but many of them are also original. Its [[PlayStation emulators|Sony PlayStation]], [[Sega Saturn emulators|Sega Saturn]], [[Virtual Boy emulators|Nintendo Virtual Boy]], and [[PC Engine (TurboGrafx-16) emulators|NEC PC Engine (TurboGrafx-16)]] original cores are notable for their high quality, compatibility and accuracy.

===BIOS===
Most cores do not require any BIOS except for the Sony PlayStation, NEC PC Engine CD, PC-FX, and Sega Saturn cores. [[Emulator_Files#Multi-System|BIOS files]] need to be placed into a folder called "firmware" in your Mednafen directory. Mednafen is very picky about which BIOS to use, but all of these come with the [[Emulator_Files#Multi-System|Mednafen BIOS pack]] and are correctly named. The ones that you might need are:
'''Sony PlayStation'''
* sega_101.bin
* mpr-17933.bin
===CUE===
* [{{MednafenURL|documentation/pce_fast.html#pce_fast.nospritelimit}} pce_fast.nospritelimit]
* [{{MednafenURL|documentation/pcfx.html#pcfx.nospritelimit}} pcfx.nospritelimit]
====Width size corrections====
Some cores have a wrong width resolution, doubt if this is a bug and even less a problem, but if you want some pixel perfect (to see better horizontal scrolling for example) you must disable Correct aspect ratio in these cores:
* md.correct_aspect 0
* nes.correct_aspect 0
* pce_fast.correct_aspect 0
* snes.correct_aspect 0
* snes_faust.correct_aspect 0
* ss.correct_aspect 0
Here is also a little list of the cores without an correct_aspect setting but its width is still wrong, so changing it's xscale values will give pixel perfect.
These cores (except PC-FX) also have a boolean setting called h_overscan which if it's enabled (1) some overscan (which is most known as black bars) on both sides will appear, but width size is still inaccurate.
All values are replaced from 1X scale, if you want 2X or 3X scale, multiply it with a calculator.
* PCE / PC-FX: 0.888888888888888
* PC Engine (h_overscan 1): 0.875
* PlayStation (h_overscan 0): 1.092715231788079
* PlayStation (h_overscan 1): 1.09375
Example: PSX [https://i.postimg.cc/6QFrs4dR/mednafenpsxbefore.png 2.0X scale] -> [https://i.postimg.cc/TwmrT29s/mednafenpsxafter.png 2.1875X scale]
