depends on the emulator, but if it has a built in way to do it, you will have better luck with that.

I've been absent a long time. Indeed you can use CE on EpsxE, as well as many others. (Snes9x and Project64, I'm sad to say, I am unable to accomplish. But expect Tables for VBA in the future.)

On another note. Hey Geri!!

I always start by finding the pointer to the emulated machines writable ram. In pSX, there is a pointer that points to where the PS1 RAM begins, so you can just set your search range to the address the pointer is pointing to + 2048KB (0x00200000, 2MB) and you'll be directly searching the PS1's main RAM. You can also find the pointers for where the sound/video/CD-ROM ram as well, but not really useful when making cheats.

That's how I make PS1 cheats with cheat engine.

I found it hard to disassemble epsxe machine code. It is entirely composed of a full engine and the same loop is used for more than a single variable.

What's happening in this case is the emulator is reusing code it's already emulated in order to increase speed, rather than interpreting everything.

Interesting, it only stands to differ a bit compared to normal memory allocation. I will see what I can, thanks for the tip.

I tried to do it but failed hard. Any chance you want to write a tutorial for doing Dynamic Recompilation?
