I will shortly have 2 core grafx systems in my possession. I bought one core grafx and then a day later found one with the super cd system 2 with the version 3 setup.( should have waited an extra day). So I guess that I will take the best of the 2 core grafx's and sell the other. Anyhow I was able to source and purchase an arcade card pro, Ys I and II (american duo version), Loom, street fighter II ce, and the adaptor from tototek to use my playstation controller. I have not recieved the systems yet and I just want to know, can I just plug this directly into my electrical outlet? Or do I need an adaptor? (I live in the united states) Do I have everything necessary to play pretty much most of the games made for the pce and duo? Am I missing anything at all? Will having the arcade card pro help out with game play on standard scd games, do to the extra ram? Also can I do a region mod on the core grafx to play us hucards?
