This "safreen" dude is quite obviously not worried about performance, just using that as a way to start discussion. He's probably looking into whether he can create a static recompilation of some popular game, target (my guess) a handheld or iPad or console or something, and advertise it (even non-commercially) as a fan-made remake. (Oh, and manipulate MAMEDEV into doing the work for him, as a bonus.)
I wonder how many times we have to say "it's illegal - a violation of copyright" before he gets it...
Even forgetting the legality of translating code via static recompilation from one language to another, there's still tons of copyrighted media (graphics, music, sound effects) in the final product.
