Firstly, if u did a search you'd probably find several existing threads covering your topic, which I cbb to narrow down for you :P
Anyway, no. The PSP Slim is not compatible (and apparently never will be) with the 1.5 kernel (for the moment anyway, there might be a breakthrough in PSP hacking =D)
Originally posted by DEVINRL: like rav3 said, if you did a search, you'll find everything needed to know, including the fact that theres a 1.50 kernel out for the new m33's
yes, there is a new kernel for m33 but i am definitely sure that there will never be a 1.5 kernel for the slim due to the new software.but hey, isos are much better than emulators, right?
