Just want to add that I tested:
One Piece Unlimited Cruise Episode 1 - NTSC-J
opening video lagged, but rest of game and ingame story vids all seemed to work perfect.
Bomerman NTSC-J
had no problems, played just past the first level.
Donkey Kong Jet Blast PAL
I have an NTSC system and TV...
btw i feel this a good time to remind you guys that sea of thieves was made by rare, who also made DKC1-3 and DK64, alongside banjo kazooie and conker's bad fur day
