Maybe. Take a look at 56A8DC9C. I noticed when HiSpeed is enabled the FPS increases and, maybe I'm wrong, but I think this is a side-effect of "speed hack" and the two are independent. Generally speaking (especially in older games), things are tied to the FPS and there is "good" reason to limit it.

are you using any specific program to access these? nothing i tried allowed me to even get into the data of the file, only letting me see header info and other useless things.

You can use any memory editor and/or debugger (I prefer Cheat Engine and x64dbg). The idea is to view the module after the processes has loaded it. You won't get far if you don't understand x86 assembly, though.

This was actually much easier than I anticipated--NOP these 6 addresses and you will have the desired effect. That said, I would still advocate for something like Cheat Engine to enable/disable this on-the-fly rather than patch this into your game permanently.

P.S.

It is probably worth mentioning these are for the English version.
