* PPSSPP JIT code has pointers, but they are all added to an offset before being used.
|
||
Find that offset so that hook searching works properly.
|
||
To find the offset, find a page of mapped memory with size 0x1f00000, read and write permissions, take its address and subtract 0x8000000.
|
||
The above is useful for emulating PSP hardware, so unlikely to change between versions.
