I found the ROF value for certain, and wrote ASM to replace it. I looked at your PSide source, this is definitely the right area. It seemed to be weapon specific, because it wrote to different addresses for each different weapon I stored.
The weapon "configuration" - COF, ROF, Ammo (albeit serverside) - is all in the same area in the ASM, around 00908**
I just assumed it was all weapon-specific. Nonetheless, it really doesn't matter. This is the same area for ROF that was in PSide (EDX+50 at that certain point).
I am noobing it out here, it feels like, but I am trying to make progress
