Just Passing this along PSP Tools to sign/convert iso files to be playable on OFW
I'll try to make this as easy-to-understand as possible for everybody, so here's the simple facts.
If you're having problems with the images, right-click and select "View Image"
1 - Many PSP games can be resigned to play on official firmware (OFW)
2 - This tool only supports .iso files (remember this, it's important)
3 - This tool has a hard size limit of 728MB right now (that's the biggest PSN demo to date)
4 - The games signed this way only play in firmwares 6.31 or HIGHER (at least until Sony decides to block this somehow)
Okay, have you read that? Yes? Good, read it again just to make sure you took it all in. Because now I'll be showing you, step-by-step, how to do this.
First, we have a few games, on the left....
