Where does one go about obtaining them, emulationwise? Megakevin ought to know, and I'm looking for arcade ones, not just CPS2 and stuff. I have enough of those. I'm looking for the kind that play in MAME, like, oh, for example, R-Type and R-Type Leo [yes, I love the R-Type series. Shush.]
I don't wanna google anything since a quick question on TPH should answer my questions and get a reliable site too.
Thanks in advance.
