I have two separate mame folders to utilize 0.147 and 0.143. In the mame settings I used the rompath to the one in 0.147. However this only displays the roms that work with that version of mame (because I only put the roms that work for that version in their respective folders). Only after I test a game and find which version it works best in do I put it in the one of the folders.
Because of this I have been using the emulator entries for the separate versions of mame, however that means that I have to forgo the information gameex automatically finds, such as game descriptions, controls, similar games, ratings, etc. This is useful information I would like to take advantage of.
Is there any way to have separate entries for mame to run more than one version of mame and merge them into one list like is possible using the emulator entries? Or is this mame settings thing really only meant for a complete rom set?
