Nope, I was not. Also, a beta of the game was sold at an event in USA by "older games" or something like that because they didn't bother waiting for the final release (the megacd audio part had a bug that took 1 year to fix).
I got some copies free to offer to some friends, as well as a bunch of megadrive games. I also got all the shipping fees (shipping the final disc to USA) refunded.
Anyway, what's done is done, I have no regret (except, again, the fact it wasn't official release supported by sonic team, geeez) ^^.
