Firstly, thanks of this great ROM which helped me understand to to make my own ROM for ACE.
How did you enabled the Haptic Feedback?
This is my ROM,
it's based on S5830XXKPB.
Deodexed, Rooted, Busybox included and RTL fix (made by the Israeli community).
also, it's a very simple to install way!
just move the ZIP into the SDCARD, flash S5830XXKPB.
get into recovery (NORMAL ONE! Don't use ROM Manager!) wipe data, wipe cache then just install the ZIP from the menu.
reboot and your all done!
