Here is a new program by the developer Choco from nextgenupdate.com, the tool is called Compiler PPC (PowerPC stands for P erformance O ptimization W ith E nhanced R ISC Performance C omputing).
The application allows the compilation of instructions PowerPC in OpCodes (Code of Practice, is the part of a machine language consists of a series of instructions that specifies the operation to be performed).
This tool is extremely useful for modding the Playstation 3, all the files . elf are PowerPC, thecompiler PPU ( physics processing unit) also allows us to compile opcodes for the files . x and x (for xbox 360).
Warning: require’s a broad knowledge of the topic.
- Enter the instructions in the box to the left.
- Enter the address that will add the operation code in the box Start Address (note: this is the address from IDA / memory, not the address HxD) and click compile .
- Copy the opcodes from the box to the right, and paste in the file. Elf to the appropriate address.
To designate a register, put the “%” symbol in front of it. For example:
li r3, 0 <— This statement is incorrect.
li% r3, 0 <- This statement is accurate.
bl (bl address)
This statement bl contains an address bl, here we can see an example:
For instructions on branching conditional , just make the statement, followed by the distance inbranch . For example:
