Well be warned, the Phantom 1 may be the best MVS to home cart adapter, but it is very finicky about what cart systems it works with. My old U.S. home cart system, s/n 13208, did not work at all with the adapter when I got it. !Arcade! replaced the slots on my cart system and then it worked. The adapter worked almost perfectly on my JPN system s/n 132xxx with no modifications.
The other problem with the MVS adapter is that MVS carts fit VERY tightly on it, they are quite hard to get off and on. This ends up being a real hassle and degrades the value of the adapter in my opinion.
Best of all is to get a cheap MVS cabinet, these days with many arcades closing, you can find them cheap. I got a very nice 2-slot dedicated SNK cabinet from an auction, only $425. MUCH better way to go . . . and having a cabinet is a blast!! <IMG SRC="smilies/smile.gif" border="0">
