Something like the programs described
here, but for the PSX instead.
Someone told me that each and every type of processor uses assembly code which can be viewed with a hex editor, but that the code was different for each type of processor. I was told that this is because each type of processor uses a different function.
I was wondering if there was a program out there where I can input some random hex data, run it through the program which contained the function that the PSX processor uses, and would give an output based on the data that I put through the function.
