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 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 Find 48 53 6A 1E 52 50 in Hex, Change the 1E value to 3C
that should be just about it
