All applications are closed with just mame open. load r-type it runs at a jerky 40% then 30secs later it just kicks in 96% (it seems to coincide with the backlight going off then coming on just the 1st time only) and much smoother with perfect sound,this seems to be the only rom that does it, but i havnt tried them all since the update tho.

The partial update info comes under the fps and speed % top right of screen (@Rushmore - which you can get up and adjust by pressing the voume down button on the side of the phone) it didnt show before the latest update i'm sure of it and it doesnt do it on all roms.

Are you aware that when the emultor is running idle the back light and keyboard light constantly go off and on every 10 secs or so. but when playing (testing) no problems with the lights.
