If your really interested, you'd have to start off by learning how to unpack the spl from the original stock ship rom.

From there, you'd need to hook it upto a common disassembler/debugger (google ida pro dissassmebler). But, before you do this you better know what 0-F is, as your going to be dealing with alot of hex numbers which translate to whats known as assembly code.

From there, it's pretty much working through the assembly code, jumping over code, adding pointers to jump over code that checks networks etc... the issue is this is alot of numbers that these guys already have been through. It is alot of work reverse engineering and it's not for the faint hearted or "I took a programming class in college". This is for the people who hack stuff up as this stuff isnt taught in college, it's all self taught.

There's alot more tools out there that can help, but when it comes down to it, you've gotta know your ASM.
