Based on 1.0.0:
1. Read 8 bytes from MAIN+0xCD17BE0 address and store it in register F
2. To register F add 8
3. To address stored in register F write 0x404E000000000000 (which is 60 in double format)
4. Write to MAIN+0x7B90F60 0x52802002 (02 20 80 52 in arm64 assembly means "MOV W2, #0x100". This is because game from this value there constantly updates nvn interval by taking W2 and going through AND operator with 0xFF, and then to result adds 1. And 1 unlocks 60 FPS. Normally W2 there stores 0x101)
Don't ask me to make it more understandable. First learn how to read cheat codes, then we can talk.
