Hi Task and Frances_Penfold,

upgrading your PSP with official firmware does not mean that you have to update to the latest version.

Maybe 3.00, 3.01, 3.03, or 3.10 could be of interest. As far as I know, there are no problems with the extra packs for Pure using mentioned versions, but you will be able to enjoy playing the game at 266 MHz. Just a thought...
