Hacking HVCA

[Entroper]

Is there a list somewhere of compatible/incompatible NES/FDS games for HVCA? Beyond the frequent minor graphical issues, I'm finding not only games that won't play (FDS Metroid loads but returns "ERR 01" when you choose a save and flip the [virtual] disc to side B) but also some that play at reduced speed; Solstice in particular runs painfully slow, around half to 2/3 speed. Has anyone experienced this and/or found solutions?

The Metroid dump might just be a bad dump. The real FDS hardware isn't exactly problem free either to say the least, so at least it's a faithful recreation
Probably not much you can do about games running slow. The GBA is not very powerful.
