Hi, mightypirate
I'm Marco ( ITA !!! ) ...
I did that conversion months ago ... then I contacted "someone" on the Daphne chatroom to talk about it ! After some months we got the "correct" drivers for both Dragon' s Lair ( Atari rev. D1 , D2 and Sidam ) and Space Ace EURO !!!!!!
They have still some kind of "sync" problem , probably due to the blue PAL screen , but they are FULLY PLAYABLE !!!!!! LIKE in THE "real" ARCADE GAME !!!
So... the process used to make those conversion is not so difficult ( ... if I was able to do that , then almost everyone could !!! hehe ) , but you MUST have the "single-file" mpeg for both games ! ONLY with a laser-disc rip ( NOT the "multiple-files" taken from the DVDs with the DVD2Daph ! ) !!!
Then you should have some video encoding programs like TmpgENC , VirtualDub ... )
Well , I have to ask you to eMail me , then we could speak "quickly" in italian , and I' d tell you HOW you could do that !
B.f.n.
Marco
