Due to many peoples uses ARMv6 devices, I made new version of Catapult. And it’s ready to download. http://slideme.org/application/catapult-0
I’ve tested on Samsung Galaxy Y, and it has better performance on Xperia Mini. But unfortunately, i can’t fix this bug (GUI RECT bug). You can’t even press start if you use Samsung Galaxy Y. 480 x 320 px is recommended.
