i just tried mm9_dlc_02-cw7.wad (the DLC wad) and it didnt work with the NTSC -WVCDUMPS wad...
and thats curious as the nfo from the -CW7 DLC wad said it was region free... must not be
(posted a min to slow as ^, but yeah doesnt work with NTSC)
as far that i have seen... when you go to the sandbox (after the 1st boss when you can ride the motorcycle around) it freezes at random points
it also freezes when you die...
not playable imo
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
