Wow, thanks very much, I'll keep my eye out for an R then. I'll check out those sites for some good games, I'm always excited when I first get into the games of unexplored systems. The whole system/arcade card thing waaaaay throws me off as well as the different cd types, but I'm sure I'll get it eventually.
For games: pcengine.co.uk is a great place to go check.
Get a Duo-R, try Yahoo.jp auctions and use a proxy bidder service. I nabbed a boxed one for 60$ + shipping.
It'll take care of all that you need really. You can play any hucard game, and any cd based game with the exception of arcade CD games.
Heres the System Card run down:
System Card 1: ignore it. I think its tatsujin here whos got like 90 of them for no reason
System Card 2: The common card. You need it for CD-ROM^2 games. Everyones got one or more of these!
System Card 3: The expensive card if you get the US version. Cheap if you get the .JP one. It's needed for Super CD-ROM games.
Arcade Card Duo: For playing Sapphire. Only works in a Duo, hence the name.
Arcade Card Pro: Same thing, but works in ANY system, and costs a bit more because of it.
System Card 3 is built into the Duo-R, so if you get a Duo-R, you only need some sort of Arcade Card.
If you go the US Turbo Grafx-16 route (I don't advise it really...), you'll need to either drop alot on a US System Card 3, and the CD attachment, or get your TG-16 region modded/use a converter, and use the Japanese version of the card instead.
Which is basically why we say find a Duo-R. They're sleek, reliable, have Sys3 built in, and in the end will cost the same , or maybe less, than if you were to got the US route!
