So i flashed Watapon on my zaurus sl-5600 with pxa250 cpu.
however, it's not faster than the standard SHARP Rom :
Bogomips are the same (397..)
ZJB reports, for Watapon and right, SHARP
int artimethic : 7,63 vs 7,68
doubl A 1,23 vs 1,2
infinite A 2,71 vs 3,6
Strings 3,47 vs 4,3
Draw 6,65 vs 8,4
file IO 2,09 vs 9,0
because of the blue crystal them i switched back to the original sharp ROM
I tried to play a video in mplayer but it seem not going better as with Sharp's rom.
Never mind, the machine does all i need
