its definately possible. iphone just haves a 480x320 resoloution and the droids resoloution is 2 1/2 higher with 854x480. also the psx emu on the iphone runs just in qvga cause the half screen is used for the controls. means the iphone haves about 5,3 times less pixels to render.
76.800 iphone psx emu
409.920 droid psx emu in fullscreen.
edit : ok. i took a look at the android psx emu screens again. seems to be its only half of the screen used. but well still 2,6 more times to calculate for the droid. i think we could reach 100 fps too sooner or later.
Alright thanks thats what i wanted to know thanks mustang
