Don't be hasty to start your own mod; all our FFT modding projects are greatly understaffed. Find out how you can help in the Recruitment section.

Hacked pSX 1.13 (to manually set fps)

Started by Xifanie, May 27, 2010, 12:50:26 pm



Hacked psxrel 1.13 (set fps)

- Download the hacked pSX 1.13
- Hex edit the new fps you want at 0x00105F08 (set by default at 120FPS)
- Make sure frame skipping is enabled: File/Configuration/Graphics/Frame Skipping

  You can set the fps very high, but it will still slow down on effects; whoever,
  AI decisions and unit movement will be completed much faster.
  You can also change the fps during gameplay with a memory editor at address
  psxrel.exe+105F08. Remember it is a float type.

  0x00105F08 : Float (4 bytes)

Just a few examples
 60fps: 00007042
 80fps: 0000A042
 90fps: 0000B442
120fps: 0000F042
150fps: 00001643
180fps: 00003443
200fps: 00004843
240fps: 00007043
300fps: 00009643
360fps: 0000B443
400fps: 0000C843

Love what you're seeing? https://supportus.ffhacktics.com/ 💜 it's really appreciated

Anything is possible as long as it is within the hardware's limits. (ie. disc space, RAM, Video RAM, processor, etc.)

<Raijinili> remember that? it was awful


About time!!

Hacking on pSX seemed so slow, because it had no way to change the FPS(as far as i know, changing it affected nothing)



I ran into this strange bug today....  and it seems to be happening only in fullscreen mode. This only occurs when running the normal pSX (no debugger). Once upon loading a save game into the world map, the game throttles at full speed....   This is not suppose to happen right?  Even turning off Frameskip does not solve this. I was recording a video that would required the game running at normal speed.


I remember I was trying to get this to work for some time now. For some reason, it just wouldn't work. Last night, I figured out why. It was rather embarassingly simple. Just turn off Vsync. Oh well.


Wait, just turn off Vsync and it will work? Awesome. Now I don't have to wait ages for the game to load and get to hacking quicker.

wow I just started using psxfin over epsxe just because some mods kept freezing for me on epsxe. I was already hating not being able to increase fps so I'm so glad I saw this post! What a QoL improvement!
