From Wikipedia:
| Quote: | | The author of a keygen typically uses a disassembler to look at the raw assembly code of the targeted program, checking either the software itself or the installer. Once access has been obtained to the program's code, the location of the subroutine(s) responsible for verifying that the key entered is valid are found. Using this knowledge, the algorithm may be reverse engineered to generate valid keys, which is then incorporated into the keygen. |

It relates to purchasable software and basically it generates a key code to use instead of buying a licenced code from the supplier.

| either the creator reversed the key check routine so he can generate valid keys or very often these days you see hardcoded serials just alternated as you 'generate' another one

Valid enough to get past the initial check maybe, but will likely never work online where the key actually gets checked against the master server.
I laughed at the fmod addition, no keygen would truly be complete without obnoxious synthesizer music.
