Welcome to the board;)
Please have in mind that you need the NTSC-J versions. NTSC-U or PAL don't work unfortunately.
I am aware, but have some spare money and I know where I can get some Japanese copies in the near future. Japanese versions of all the Resident Evils were available from a shop that were open at two previous PAX events (one Prime, one East). I didn't pick it up then, though of course now wish I had. I'm currently in California with family for holidays and going to a mall in a short bit which has a game specialty store that has foreign games though so going to take a peak in today with crossed fingers as years ago I did buy the Japanese version of REmake from there. If all else fails, always online. It's not too expensive yet, searching it up right now you can knab a new copy for $100 or so and a used copy for $20-40 (for Outbreak 2 at least), but I suspect with this it might get more expensive in the near future.
Thank you so much for doing this, always have heard great things about the online from this game and the one time I tried it I really enjoyed it. I actually had been holding out playing my copies of Outbreak until online was available, but as a collector I don't mind going out of my way to find the Japanese versions of the game. Incentive, anyways.
