@mitu ok!!! All is perfectly setup. I was doing a bad thing here on the mame´s menu, I thought the button was configured just when I pressed the key in the joypad, but not... I have to press only one time and then wait. Ok!! alll my problems are solved. Thanks a lot to all of you.

@caver01 - Thank you for your help...basically with the IPAC, you just run the wires yourself instead of the wiring set with EG STARTS kit

in all honesty its easy to setup but you need to understand ra and it needs documented you can go back to the old way like above or set up up in controls both work im sure mark will get round to documenting it for people

@grant2258 said in History.dat in mame2003-plus?: cp /opt/retropie/libretrocores/lr-mame2003-plus/metadata/history.dat ~/RetroPie/BIOS/mame2003-plus/ Or hardlink the file to save unbelievable 6 MB disk space. :) ln /opt/retropie/libretrocores/lr-mame2003-plus/metadata/history.dat ~/RetroPie/BIOS/mame2003-plus/history.dat (I'm back from a gamer's bar and a bit drunk right now, so cut me some slack, please. :*) ) edit: Aaaand … I forgot the history.dat at the end. Corrected.

@pandamkii You don't unzip MAME roms, this is the way they're distributed they'll not work otherwise. If you're considering adding MAME to your setup and you're a beginner, then please read the Quick Start and the topics linked on that page. It will answer most of your questions and will help you understand how MAME rom(set)s work.

@unspacey To put it another way, by changing the "setting" as you describe it to use 2003, what you are doing is telling RetroPie which version of MAME you want to use. To succeed, the game you are launching must be a ROM from the version .78 set.

@vahnxdean Play it on windows with mame or buy it from steam. That game requires a newer version of Mame and I highly doubt it's playable even if you did get it running on the pi.

@amishgamer Did you watch... I watched it as a complete beginner wanting to use that DAT. It worked great for me first time.

@alistaircg which folder are you running the roms from? /roms/mame-libretro?
