There is a unofficial Daedalus that has began circulating around the internet. Unfortunatley, I was not able to find any information on who actually made it.
This is a Frame skip mod of Daedalus R9, with frame skip enabled !!
Yes, thats right. I've tested this myself, on frame skip 3, and it ran 34 fps outside (and inside) the castle !!
And it ran 20+ fps in world 1.
This is the fastest Nintendo 64 emulation on PSP so far. So while we wait for the official R10 from StrmnNrmn, this should keep us occupied.
