That's 100% correct. Although I can use the knowledge I gained while working on pinmame, I can't use the code due to it's license. Plus, it was actually far easier to write my own emulation core then to try and take out all the junk in mame we didn't need, so I'd have done it that way even if the license was friendly. Mame's core is very flexible, but doesn't make for optimal performance, especially since we don't need all that flexibility anyway.
