Opcode Editing

Hey there guys.
I would like to ask if its possible to edit Opcode of an address at the process?

Example..
Editing the address 0048C8A8 and its OPcode is "call 0048Cd15".. Is it possible to edit it to another one that can be typed?

It's definitely possible, but the hard part is converting those opcodes -> instructions and vice versa. I know that BeaEngine can read opcodes and convert to instructions but not the other way around.

If you Google 'convert opcodes c#', you'll find a thread on the CheatEngine forums, might help you. The crap thing is that the links are dead since they're hosted on MegaUpload so yeah..

If you have enough time on your hands you can write your own C# library to follow the instruction set and convert opcodes -> instructions. From there it's a pretty big leap back to opcodes, but it should be possible if you properly identify the components of an instruction (i.e, maintain the underlying opcode of an instruction within a structure and modify it as needed)

Sounds like a fun project, I may have a crack at it when I get some free time :3

I still have the files from that post. Opcode.cs, Opcode.dll and the scripter.
But i could never get them working.

I just use CE to convert the opcode and write it as a byte array.

I see. I thought it was just easy just like from Cheat Engine...
I suppose I should also study it even I'm just on the basics.

I'll look for more information about that over the net..

*Solved.
