[HELP] With creating a PSP-compatible ISO

I downloaded a game (Worms Open Warfare) and it turned out as a folder. How do I change that folder into an ISO? I have used normal ISO making programs for Windows but they didn't work. Any suggestions for programs that will make ISOs compatible with the PSP?

 

if u already downloaded that use winrar to extract the files then after extracting u should get a ISO FOLDER that has an ISO file in it, Copy the ISO file on ur ISO folder of ur Memory Stick if u have a custom FW after that put a UMG game (be sure u turn off ur auto load UMD) and ur game should work fine.

 

nah, use UMDGen dude, select the files and then UMDgen will create a iso for the PSP !

 

if you have a PSP GAME folder and a UMD DATA BIN file you need umdgen
start umdgen ,drag and drop ,save as iso

 

Thanks! It works now!

 

Thanks will try it hope it works for me
