Can I play UK PAL games on an Australian PAL GC?
Yes you can, because they both use the PAL video standard. This is also why you can’t play UK/AUS games on a US/JAP GC. A US game wouldn’t work on a JAP GC because although they both use NTSC they use different variations on that standard. If you are desparate to play an overseas game get a Freeloader disc.
