MAME ROMs that run in a vertical aspect like DoDonPachi need to be rotated within MAME before resolution switching and aspect correction will work. Meaning that the MAME game will look just like the original hardware. There is resolution detection to ensure MAME games will be displayed in the closest available resolution but drawn at their native resolution within this resolution. Some arcade resolutions can be very different from consumer CRTs. For the best results super resolutions are the way to go. This is due to mid-scanline resolution changes on the original hardware. However, some games may have unwanted results. These modelines are more accurate giving exact hz. If native resolutions are activated you will need a whole new set of modelines: Any other resolutions will be ignored and native switching will be activated. The only compatible resolutions are 1920, 25. This can be changed within the retroarch.cfg. It is displayed just under the CRT switch option, which can be found in video settings. Ideally install all these modelines and everything will work great. Some games will require higher PAL resolutions which should also be installed: The above resolutions are NTSC only so if you would be playing any PAL content please add PAL modelines: Install these modelines replacing 2560 with your desired super resolution. The minimum modelines for all games to switch correctly are: If you are running Windows, before enabling the CRT SwitchRes options please make sure you have installed CRTEmudriver and installed some modelines. With CRT SwitchRes enable RetroArch will start in 2560 x 480 60. However, you will need to restart RetroArch to disable it. CRT 15Khz Resolution SwitchingĬRT SwitchRes will turn on, on the fly. Instructions for compiling and installing RetroArch can be found in the Libretro/RetroArch Documentation Center. To configure joypads, use the built-in menu or the retroarch-joyconfig command-line tool. Users only need to configure a certain option if the desired value deviates from the value defined in. RetroArch will on startup create a config file in $XDG\_CONFIG\_HOME/retroarch/retroarch.cfg if it does not exist. These can later be tweaked by using a config file.Ī sample configuration file is installed to /etc/retroarch.cfg. It is not recommended to change this unless you know what you're doing. The default configuration is defined in. Dependencies (Console ports, mobile)Ĭonsole ports have their own dependencies, but generally do not requireĪnything other than what the respective SDKs provide. To run properly, RetroArch requires a libretro implementation present however, as it's typically loadedĭynamically, it's not required at build time. ![]() RetroArch needs at least one of these audio driver libraries:
