It seems there was a bunch of these games that were translated but scrapped at the 11th hour. I'd love to know why and someone should come forward with the info.
That said: I'd also like to see these leak, but I'd doubt that'll happen and if it did it wouldn't be big news since there is no X-box emulator for the masses to run them.
Yeah, we reviewed Rent A Hero, too. It was all ready to go.
I had the disk for many years after the fact, but I think it was lost to time. It wasn't playable on a regular Xbox, mind.
