In 5110B it performs pretty well, Shenmue is glitchy though. I think it's quite optimized considering it's in alpha state, and it clearly uses frameskip auto by default. But quite surprised. I will test it in IBEN L1 soon and probably on next coming GPD devices, so I will compare between them.
Cdi images work fine too, no need for gdi ones (though gdi are usually better dumped)
