I tried a bit with a couple games that I've always wanted to play on the Wii (Vandal Hearts & Torneko: The Last Hope) and tried over the years and different versions of WiiSX and I have to say that I am very, very impressed how well they run with the last compiled version by SaulFabre, even more having in mind this is still in early stages.
Both games had good frame rate from what I could tell, and the audio for Torneko seems smooth too! Overall the performance on both was by far the best I've seen so far, although my test was quick.
I need to compare Vandal Heart's audio with playing it on a PS1/2 because all versions of WiiSX previous to this one seemingly have missing sound channels (not only for this game, but I know this one pretty well so I can tell easily). This version seems to have more instruments/channels if going by memory so it's a great improvoement, although I remember the music having a bit more reverb.
Nonetheless, it is remarkable and exciting!
I confirm that exiting does not crash the emulator and goes back to HBC.
I would want to ask to emu_kidid if it's possible at all to have a way to disable the bilinear filtering.
