Hex disabling the timer..

Alright, I'm trying to disable the timer, not by setting every level time to 0, but actually disabling the clock through hex edits, Like in BMF's SMO hack. I've tried fiddling with the ROM address, but no matter what byte I set, it's either too slow or too fast. Then I fiddled with the RAM address of the timer, it worked, but weird things started to happen with layer 3 making it unusable. My question is does anyone know a way to disable the clock with no side effects?

Change 3 bytes at 103F (headered) to EA. It simply won't tick.

Or, change 2 bytes from 0x101A to "80 79".

It worked perfectly. Thanks guys.
