Tried Soul Calibur II with three different nintendont versions (2.167, 2.184, 2.190). Finished arcade mode and played a bit of the weapon master mode. NO FREEZES whatsoever. I use a 251 MC. 1:1 pal ripped iso i own.
Try a smaller MC size, double disc games are notorious for this, it has been discussed before IIRC.
Also make sure to name the isos correctly (game.iso and disc2.iso) and have full isos.
I have a report to do! I was able to launch baten kaitos 1 and 2 this way, fisrt I boot the disc 2 and then when starting a new game it switches to disc 1 and I can play normally, but for baten kaitos 2 this way the wii shuts down when it switches to disc 1, I can confirm that baten kaitos 1 it's working now. I will try to download two new dumps of disc 1 for both games and test again. Nintendont 2.191 and mem emu 1019 blocks progressive on.
