(adsbygoogle = window.adsbygoogle || []).push({}); Hey, I'm guessing you guys know that someone on 360 hacked Campaign and Spec-Ops (such as high jump, super speed, inf health, inf ammo, etc.)

Well, I have some good news and bad news:

Good news: I know exactly what and how did he do it. I know the dvars he used to achieve these effects. I can confirm that SAVEGAME.SVG does include data of both Campaign and Spec-Ops! and that the save data of both 360 and PS3 are very similar to each other!

Bad news: ... If you change data in the SAVEGAME file and load it up on MW2, you'll get an error saying that the file is corrupted. This is because the checksum in the editted SAVEGAME.SVG file remains the same, and hence corrupted.

This is just the final step. We just need to update the checksum and we're set!

So far, I'm not 100% sure where this checksum may be. It could be at the very beginning at the top of the file but I'll need to run tests and compare what's changed.

Do you have some expierence regarding checksum? Can you confirm that PS3 data saves use CRC-32?

Here this may help you, remember to rep the author if it does.
