Re: Emulation/ROM Hacking
I thought emulators/ROMs were only illegal if you hadn't actually purchased the console/game.
Anyway, about the playthrough thing - people probably wouldn't mind that much if you used a ROM for it. As long as you didn't go 'HEY EVERYONE I'M USING SUCH-AND-SUCH EMULATOR AND SUCH-AND-SUCH ROM WHOOOO', I don't think you'd get into any strife because of it.
