i am wondering if it is worth downgrading from 2.5 to 1.5

uh you cant downgrade 2.5. you can only down grade 2.0 sorry

hopefully enough someone is making a downgrader.But seriously man, dont be persued by sony.They try to make soo many col things and games for psp, just to make u upgrade to 2.5.Dont be persued by their actions.Sony will keep fighting to make more and more firmwares, and people will keep fighting and fighting to make downgraders.Hope fully time will pass and they will make one for 2.5.

Someone please post as soon as a SAFE downgrader from 2.5 is created. I really want to put old games on my PSP.

well, there is 1 homebrew for 2.5, its called hello world, but it only works with GTA in your umd drive.

hello world text comes up on ur screen when the trojan is nearly finished on the 3rd rebot so that means hello world was the maker of the trojan (bricking psp!)

Yes, but that is only on when you go and mess with the system files. Like, the main file that is suppose to be on the PSP, they deleted and added the hello world to it, (there's actually more than one theory.) Also, there's one where if you click on the photo icon on your PSP, your PSP will show a quick flash of words and shut off your PSP. After that, it is forsure a brick. If you watched the clip of the "brick PSP", it's all on there.
