How to hack fps game, just use hex editor software to change hex code
Theoretically you can patch these bytes to run at any FPS you want it to, 240 can even probably work, but i wouldn't personally recommend going that high.
1E = 30, 3C = 60
First off we'll patch Game Speed to 60 as you'll turn into Sonic in game at a capped 60 otherwise.
IDA Address: 0052E7C4 If you use hex editor, Find C7 05 C8 3E 6B 00 1E 00 00 00 in Hex, Change the 1E value to 3C
Now FPS Lock:
IDA Address: 0043F8B8 If you use hex editor, Find 48 53 6A 1E 52 50 in Hex, Change the 1E value to 3C
that should be just about it
Hex Code fps : 1E =30 fps, 3C =60 fps, 5A = 90 fps, 90 =144 fps if you use monitor high refresh rate 380 hz, hex code 17C = 380 fps, if you use monitor high refresh rate 500 hz, hex code 1F4 = 500 fps very smooth and fastest
Don't Forget to go to NVIDIA Control Panel to setting max frame rate accordingly your refresh rate monitor
