2 Questions: Radeon command line? Can 2 Mame's exist on same pc?

[kenclops]

So, I was thinking about using 2 external application slots in gameex to allow myself to switch between balanced and and performance mode using an Ati Radeon card. Are there any command lines that would help?

Second, can two Mame's be installed on a computer, one with one set of roms, the other with another set of roms?

I don't know about the first question, but regarding the latter, yes you can have as many mames as you like on your computer (and in GameEx). For the other Mame's you can just set them up as a regular emulator in the emulators part of GameEx.

Or...

If they are two different types of Mame with different games -- like Agemame or Misfitmame you can merge them together with Multimame and use that for the main mame in GameEx.
