I am an average PC emulation type person and have only recently started to work with my PSP on emulation. I have been very thankful for the help that I have already received here in the forum. As I get further into the PSP emulation the more I run into questions with all the information that is out there on the net. So, here are a couple of questions that I would like to throw out there and see what comes back. Depending on what comes back I will see if I can keep one library of ROMs and use it on two different emulation platforms. 1) Is is true that the same ROMs that I run in MAME on my PC can be run on MAME4All on my PSP? Also, Neo-Geo and CPS1 / 2 ROMs? 2) Is there a Rom conversion process that needs to be done as the ROM version is married to the PSP emulator version? Thanks.
