I have been busy with the trainer. One thing I have already added is the ability to increase the speed much further than usual. The default speed values are 1 2 3 4. However, with simple hex change, this can be made up to 7F (although there is no speed increase beyond a much lower value for some reason). The speed doesn't work as I expected though. 1 2 3 4 all have distinct speed ups. But later on, there is a higher ump at around 1A. The comparison to change is at 005FE608.
Anyone shed light on how this value decides game speed? I will add this tweak to my trainer, but knowing how it all works properly would help also. I am a little busy to go into it in detail.
