I don't yet really have a want list formed for this system. Most interested in platformers. Followed by shmups. Some puzzle games, RPGs, or fighters OK too. Text adventures, strategy, sports, etc, are unlikely to be of interest. Still almost anything good is an option. My system is a region mod Duo-R.
Let me know if there's a cost difference between US and Japan versions. Be patient, I'm not familiar with Turbo prices. I'd rather deal with minor trial and error than spend way more for the same game.
Incomplete is generally preferred on hucards. It can be a major savings for some titles. Leaves more money to put toward games, rather than clutter of manuals/etc I rarely read anyway.
CD games I'd like the case inserts when available. Don't need spine cards if they cost extra. Not my thing.
Sample list of games I'm considering to buy:
Alien Crush
Devil's Crush
Neutopia
Neutopia 2
Bomberman 93
Bomberman 94
Star Parodier
Blazing Lazers / Gunhed
Ordyne
Final Soldier
Galaga
Street Fighter II
Also could use an Arcade Card Duo. Maybe a better model controller too. These early Avenue Pad 6's like mine aren't all that great.
