So once you have the correct address:
Right click, find what writes to this address.
Move in game and go back to CE. Right click the on the line which appears in the list of instructions window and choose NOP this line of code.
Change your value of the speed address and it will stay at that value without changing back. (No need for freezing)
If you wish to restore it to normal click right click on the instruction again and choose show in disassembler, right click the highlighted line and choose restore with original code.
I hope this makes sense![]()
