This can be done reasonably easily with Euro MCD games, but Jap ones are finicky (something about the boot code being smaller) last I looked into it. I believe the tool used is called SCDconv, but don't quote me on that...

If you want to play the originals, you're either going to need to get a foreign system, or do a BIOS mod.
