Can someone explain to me how "Dark Alex's" psp version 3.10 works?

Question

I have version 3.11(the regular version) I was wanting to downgrade to a 1.5 than upgrade to "Dark Alex's 3.10,With His 3.11 Can I still play Games created for version 1.5? and will it still have the browser?

Answer 1

Dark Alex's version 3.10 (3.10 OE) can play any games for 1.5. It also has all the bells and whistles of the latest firmware. So it is the best of both worlds.

However, the bad news for you is you cannot downgrade to 1.5 with 3.11. There is no know downgrander exists for 3.11.
