Well hot diggity dog is this exciting. Princess Crown is a really fun game, and it's tragic that it never did see a localization officially before, or even the PSP port. Tippin my hat, godspeed.
Just a question. Would it be possible to actually replace the files for the Saturn translation into the PSP iso and repackage it? I've crawled in through the iso a couple times before, and it seems that the files are indeed similar.
