Hold L and press HOME: reset emulation.Press Home from this screen to exit to the MAME4ALL menu.

(SELECT+Up=credits 2P, SELECT+Right=credits 3P, SELECT+Down=credits 4P) A vast majority of my mame games run under lr-mame2003 while just a couple use lr-mame2000. I already have lr-mame2000 and lr-mame2003 installed and working. I’ve had MAME issues with some games/ROMs and thought I’d try to install mame4all-pi. Put all file and directory names in lower case. I’ve been using RetroPie for probably 2yrs now and it’s worked pretty well. NOTE: File and directory names are case sensitive. The process is best explained by this YouTube video - the only difference is that you will be using clrmame_roms.dat rather than other files. Please use the clrmame_roms.dat file to convert romsets from other MAME versions, by using the ClrMAME Pro utility. Romsets have to be MAME 0.34 final version ones (December 1998), but there are also some new added romsets from later MAME versions, as well as modified romsets. ROM namesįolder names or ZIP file names are listed on 'gamelist.txt' file. Games have to be copied into the /roms/ folder. Compatibility for this PSP version is more limited. The original GP2X port supported 1204 different romsets, listed on the gamelist.txt file within the release. The compatibility list for the GP2X version (on which this port is based on) can be found here: This PSP port, despite its name, is unrelated to this later project. The same developer would later start the 'MAME4ALL for GP2X' project - which supported a wider romset, and had its last release in March 2010 (version 2.5). MAME GP2x saw its last release (version 5.1) in November 2007. PSP MAME4ALL is port created by TTYman, and based on the MAME GP2x emulator developed by Franxis.
