'''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.

====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]
===Cheats===
* Rename the files you want to transfer with the names of the RetroArch memcard files.
* Place the new ones in the system folder.
====Using Memory Card Manager 1.4====
Another option is to use Memory Card Manager 1.4 to extract a separate game saves from a shared memory card file.
The utility has support for next memory card formats: *.mem, *.mcd, *.mcr, *.gme, *.ddf, *.psx, *.ps, *.psm, *.vmp, *.VM1
[[File:memory_card_manager.png|400px]]
It allows to transfer each of the game saves from a shared memory card to a .mcr memory file used by Mednafen. As it was described above you just need to start game and check for '''sav''' folder inside Mednafen system directory. Open with Memory Card Manager 1.4 the memory file created for your game by Mednafen and open the shared memory card file from which you wish to transfer a save entry. When there would be a dialogue 'Do you want to replace 'SAVE_ENTRY_NAME' click 'Yes' and then save the file to the '''sav''' folder (the older one should be replaced).
==Frontends==
* Sony PlayStation core is accurate but slow
* Only supports 2 players on Genesis
