Hello everyone!
I would like to know if it's possible to change an option in mame.ini or something similar in order to be able to choose which game version I want to play (instead of loading automatically the parent one).
For example I have a merged set of Street Fighter II': Champion Edition, with tons of crazy hacks, all inside sf2ce.zip; and I want to play some of them without dealing with all these different versions in Launchbox. So I launch the game normally from BigBox, and when mame load the merged set I want a menu asking me which version I'd like to play. I know a similar start menu can be shown to choose a specific BIOS, and I'm pretty sure that many years ago I saw a menu in-mame where I could choose different game versions... Does anyone Know if it can be done or it was a dream in my head ??
