I just played SMG from startup. It doesn't crash, I don't know where it crashs with the old version. The video is fast, but sometimes not full speed (maybe ~95%) at PAL. I used a normal TV, I don't know if higher resolution is slower. I hope that further optimization can help (e.g. I can remove a memory copy and transfer more at once).
It is possible to include also support for patched DVDs. I don't know if I include it in the first release, because I need to make 2 loaders.
I don't used Waninkokos DIP module. I patched the normal DIP module. The source code is smaller, but seems to have much higher compatibility. It is faster, because interrupts are used. I choosed it, because rewritting would take longer.
