Personally, I think the PSP would have died a long time ago...thanks there's Custom Firmwares. The boost of PSP sales was realized because of Custom Firmwares which maximize the use of PSP. And as for the PSP games, custom firmwares may have some say to it, both negatives and positives. However, Custom Firmwares shouldn't be blamed on/for the low sales of PSP games. And a lot of people are not using and/or buying the PSP because of games or just because of games. I personally don't mainly use the PSP for games.
