Hi and welcome aboard!!
In my humble opinion, you have the finest setup to play those lovely old games
You just need now whdload to be able to play the games straight from the HDD
Dont worry about "compatibility" isses. As far as i know, most 30/050 accelerator cards work pretty well with those games...
BTW, which accelerator have you bought? In the worst cases, if a game is not compatible with your accelerator, you can disable it to be able to play THAT particular game
Cheers!
