In the current "jzIntv" port Atlantis, Beauty & Beast and Demon Attack don't work... after the ROM is loaded the screen becomes black for about 10 seconds and then the emulator crashes (like when you "reset" the emulator without any ROM loaded).
PS: I noticed that when you enter in the file browser, there isn't a button to come back in the main menu, maybe it could be a good thing to assign this function at the select button!
