RAW cheat codes can also be entered via the console menu: The cheats menu can be accessed with ALT+C. Mednafen supports the usual cheats such as GameShark, Code Breaker, and Action Replay. Here is the list of options from the cfg file to change from 0 to 1 if you don't wish to have the limit. Mednafen's default settings are true to the original system limits, but this can be disabled in the cfg file. Most systems got around this limitation by alternating which sprites were on screen each refresh, causing the sprite to flicker. This is a feature on older systems, due to hardware limitations, that makes it only display so many sprites could be on screen at the same time. Press Alt+Shift+2 and so on for each additional controller for multiplayer. Once in-game, to configure your controller at any time, press Alt+Shift+1 and it will guide you through the setup. Do this for port2 if you wish to play multiplayer games with the features of Dualshock controllers. To enable analog sticks and rumble on, open the mednafen-09x.cfg file, search for '1' and change gamepad to DualShock. For example, in Windows, the command would look like C:/Emulators/Mednafen/mednafen.exe C:/Roms/Nintendo/battletoads.nes Mednafen requires no special commands, such as the desired system. To load a game in Mednafen, simply drag and drop your rom or CUE file onto mednafen.exe, or if you prefer, you can use the command line. See the Cue sheet (.cue) page for more info. Ensure that the CUE sheet is properly set up in order for the game to run. The ones that you might need are:įor most systems, Mednafen only needs the rom file but to load, Mednafen requires CUE sheets to know where the music data is. Mednafen is very picky about which BIOS to use. BIOS files need to be placed into a folder called 'firmware' in your Mednafen directory. Most cores do not require any BIOS except for the PS1, PCE-CD and PC-FX cores. RetroArch uses the Atari Lynx, PS1, PCE, Neo-Geo Pocket, Sega Saturn, Virtual Boy, and WonderSwan cores of Mednafen, so it might make sense to use that instead. It is unknown at this time whether Mednafen's GBA core is better than VBA-M (but it's likely not true). This is before the performance/accuracy/balanced cores - 0.50x territory - with a couple of changes by Ryphecha. For instance, the SNES core is based on an old outdated version of bSNES. These cores might even be based on out-dated versions. Other cores are less useful, as there are better options in stand-alone emulators (NES, Genesis, Master System and SNES). Mednafen only has a command line interface, so its interface might be slightly challenging to people that have never used an emulator with a command line interface.
