How do i select a different core for a specific mame game

[dalehitchy]

I have about 100 roms and some only work in Mame 2003 RetroArch Core and others in 2010 / 2014.

Is there a way to get specific roms to use a different core?

I don't know what it is about mame roms and emulators that i find confusing so maybe im doing something wrong and there is an easier way.

Hi @dalehitchy, MAME can be very tricky. Your best bet is to find a complete set of MAME ROMs that works with the latest versions of MAME.

Like Jason said your best bet is to get an updated rom set and use a newer build of stand alone Mame.

But to answer your question specifically, if you are using Retroarch Mame and wish to use a different core for a specific game. Right click the game and edit, then go to the emulation tab of the edit window.

Turn on Use Custom Command-Line Parameter and enter the following:
-L "cores\core_name.dll"

Obviously edit the core_name to match the name of the core dll you want for that game.

You can also setup separate emulator entries for separate cores. If you have a large number of games that need to be switched from one to another that's what I would recommend. I have instructions for doing that in the following post:
