I have most of the games released for the Turbo both US & Japan, but not all. Crowning jewels...Dragon Knight & Graffiti which I got for about $30 in mint condition on ebay, along with Puyo Puyo Tsu which I got for about $40 IIRC. Those are some damn good deals if you ask me! Still trying to acuire Madou Monogatari for under $100. I have all the standard stuff like the Exiles & DE 2, Beyond Shadowgate, Dynastic Hero, etc. Hu's...uh, I think Photographboy is rare, didn't pay much for it. Same goes for Coryoon. I used to have the Hu of Bonk 3, but, sold it, wish I hadn't, but I do have PC Genjin 3.
I have all the standard semi rare japan releases as well like Drac X(not rare, but, expensive), Fausette Amour, the Spriggans, Nexzr, Horror Story(pretty hard for me to find actually), Kaze Kiri. I can't think of anything else off the top of my head.
I used to have some original test discs from TTI of Bonk 3, Might n Magic 3(of which I don't have an original of), & Super Air Zonk, but, traded them for the real games of Bonk 3 & Super Air Zonk, along with Exile WP, DE2(both of which I owened, then sold, then regretted selling, like alot of my other games), & I think I also got a couple hundred bucks cash as well, besides the game trade.
Oh, I used to have Sylphia, sold it, REALLY regret it! I used to think of that game as sub par, but, since I sold it, I downloaded it, & made a new soundtrack for it, so I really REALLY regret getting rid of it. However, I have Steam Hearts, which I regret buying. I can't seem to even get half of what I paid for it, & the Steam in it, IMO fits nicely for the game being a Steaming Pile of Crapola! I'm not into Hentai, only bought it cuz it was a shmup, & I've played worse, Legion comes to mind, as does Deep Blue, but, it's still stinky, & would rather have my damn Sylphia back!
