Ha! What an awesome collection of games! Only half of R Type... I'm surprised!
Still, it is a neat combination... especially if you have a PCE GT and don't want to lug a bunch of HuCards around.
I can tell you that this seller is reliable (well, at least he was 2-4 years ago when I used to buy stuff from him). Everything was as described (i.e. when he says mint, it is in mint condition). He has sold these 4-in-1 cards before (I remember bidding on some of them... like the 4-in-1 with Blodia, boxyboy, etc. etc. ... Yes, I wanted it because I wanted to show it off a Blodia 4-in-1 to GUTS).
