These are the lines in raw_rec related to small hacks. In order to work them properly on 550D and 650D, we should know the timer addresses for those cameras:
/* change dialog refresh timer from 50ms to 8192ms */
uint32_t dialog_refresh_timer_addr = /* in StartDialogRefreshTimer */
cam_50d ? 0xffa84e00 :
cam_5d2 ? 0xffaac640 :
cam_5d3 ? 0xff4acda4 :
cam_7d ? 0xFF345788 :
cam_700d ? 0xFF52B53C :
/* ... */
Other way we get an error like
hackerror at 0
expected e3a00032, got 0
My question is, anybody knows these timer addresses yet for 550D and 650D?
Or may be devs can give us some clues to how to figure them out?
