A forge mod with the ability to create + save your maps.
First of all, i'll give credit:
A special thanks to ModsBABY (and everyone who helped) for creating such an awesome Forge patch.
Also, thanks to You must login or register to view this content. for converting the patch to PC format.
How does it work?
Once you save your map, it ends the game and logs all the data my program needs to know in the MW2 log file. Then, you'll have to open the log file in my program, which converts it to valid code.
Link contains the PC Mod plus an XBOX patch (unconfirmed working)
I believe this can be converted to PS3, but you will need a jailbreak (3.41) so you can FTP the code to PC.
I'll work on it tonight... Shouldn't be an issue... I'm going to use the command line method... The only thing is it gets annoying if it has a custom gsc.
EDIT:
It won't work on a console... Only the forge mod itself not the save feature... The save feature tries to save to a mod file therefore it won't work on xbox or ps3 only pc. You could make a map one pc and take the code and put it into a ps3 patch xD
