This situation described in user manual. Main speedup is possible with decreasing finegrain_cpu_speed via manual editing .uaerc file, also a little speedup will do function 'several thread for video' at SDL-settingshttp://media.wix.com/ugd/5318cc_b987aa4c8a234f77b3ec85f16d4ba773.pdf
Attention: Android port of E-UAE does not have any UI interface!
To configure E-UAE setting please open .uaerc file via any text editor. It’s located in
android/data/sk.amiga.amikit/files folder (make sure the hidden files are shown).
On Samsung Galaxy SIII phone it takes about 2 minutes to boot AmiKit. If it’s too slow
on your device, try to decrease the finegrain_cpu_speed value, for example:
finegrain_cpu_speed=32. If audio doesn’t work as expected, increase the value.
Increasing the value (to eg. 128, 256, or 512) makes the AmiKit slower, though.
When AmiKit runs for the first few seconds, the logo screen is displayed as well as
button on the top „Change device configuration“. Press it to access the SDL-settings.
You can setup On-Screen, Mouse, Video-settings and much more.
We recommend to enable “Video Settings” -> “Separate thread for video“ as it will
increase performance on some devices.
