This is based on the Mednafen v1.29 source code with various hacks to make it work for AmigaOS4. This is version 1.243. Version 0.122, since version 0.107 (first release): - Attempted to fix sound issue. Version 0.135, since version 0.122: - Compiled using GL4ES libraries - Remove screenblanker from appearing whilst using mednafen - Always call de-initialiser rourtines on early exit instead of returning without cleanup - Icons are now added; thank you Samo79 Version 1.186, since 0.135: - Built using latest CLIB2 (afxgroup). This seems to solve the DSI errors that occur due to threading - Added versioning - Changed the window title to include the version of mednafen, game and module - Using CLIB2 seems to fix the GBA module; so now this is available but untested - Sega Saturn also builds, but I have not tested it -- Basically, all the modules build - Incorporated Samo79's great contributions which includes more documentation - Extract the LHA and READ the section below titled "The configuration file" Version 1.243 since 1.186: - Fixed the minimize gadget not showing on initial window mode startup - Added the SegaSaturn (SS) module by forcing building via 32-bit PPC code; this is very slow since a quad core CPU is required - Fixed a slow down caused by linking with SDL2/GL4ES library that was dumping debug information to serial due to a non-release build - Linked with bleeding edge (at the time of 14/12Dec/22) GL4ES, SDL2 libraries Mednafen is a command line based multiple-console emulator. You run it from the command line. Read on before invoking it; PARTICULARLY the next two sections. You can use wrapper programs like EGame to avoid using the command line. === The configuration directory: === - The first thing Mednafen wants to do is to create (or find) a configuration directory - You either need to set an environment variable named HOME or MEDNAFEN_HOME - MEDNAFEN_HOME is taken in preference, and it should contain the full path to the directory where the MEDNAFEN configuration (will) exists. If I run: "SETENV MEDNAFEN_HOME SYS:S/.mednafen", then Mednafen will look within there for the configuration files, saves, etc - If MEDNAFEN_HOME is not set, then Mednafen will use the environment variable HOME instead. It behaves differently, though, since Mednafen then assumes that there is a ".mednefan" folder inside of HOME - If either of these variables have a trailing '/' then things will not work properly - TLDR: Create an environment variables named MEDNAFEN_HOME and give it the full path to the configuration folder - If none of these variables exist, the game will not run anyway === The configuration file: === The default configuration file can be used, but do the following: - Change "cd.image_memcache" to value "1" (Optional, but advised) - Change "sound.period_time" to value "100000" (Definitely) - Change "video.glvsync" to value "0" (Optional, but may help) - Change "video.blit_timesync" to value "0" (Optional, but may help) === Useful key commands to know: === - ALT+ENTER => Toggle Fullscreen - ALT+SHIFT+1 => Set up your controls for whatever module you are playing === Built with: === - ADTOOLS GCC 11.3, SDK 54.16, SDL 2.25.0, CLIB2 (afxgroup) + GL4ES === Hardware considerations: === This port of Mednafen has been tested on an AmigaOne X5020 and the Playstation module is definitely playable - even though the recommendation is a dual core CPU. I have also tried it on an X1000 with a 7950HD with relatively poor results.
