Sounds like a plan - though there are several ways of upgrading to custom versions of 3.x that also allow homebrew, PS1 games, that kind of thing.  I haven't tried them.

My only advice is to make sure that you download the software from reliable places.  There are a number of 'om1god iv downgraded it using this amazing exe' sites which will run programs/updates that will totally brick your PSP.

i was thinking of using a custom firware but then i though it might be better to use 1.5 + devhook for getting into the hire firware versions.

i was shocked when i looked this all up tonight its all got a bit cofusing but it seems to be going well so far i had to update to 2.71 then install alexs 2.71 homebrew enabler which went like a treat then install the downgrader which again went fine now im just downloading the 1.5 firware and we will see what happens.

to think i was just using the old fanjita gta loader way :)

btw the site im getting this stuff from is here.

You can play all your yabasic programs...

Or you can play module files or ST tracker files

Lots of other homebrew at
www.ps2dev.org

I'm not a fan of qj.net stuff. 99.99% of them are idiots following the one bright Pied Piper.

cool!

bte the pspyabasic runs better on 1.5 than it did on 2.6 gta ( ie a lot more stable ).

im seriously thinking of upgrading to dark-alexs 3.10 oe firmware i can still downgrade to 1.5 from there so thats cool.
im just wondering how compatible home brew will be with the firmware i mean will it run all homebrew like 1.5.

tried it im now running 3.10 oe - a and i must say its brilliant i can run my umd games at 333mhz now which really does make a diffrence and also i can use the forth level of brightness on the sceen without the charger.

now the inportant part is that when i boot up if i hold the r shoulder button it goes into safe mode then i can choose whether i want to run the games folder on my memory stick in 3.10 kernel or 1.5 so i can still run all my homebrew stuff.

theres also a lot more stuff that can be messed with ie turn off/on the sony startup logo etc.

it was quite a long process i had to wait around an hour and a half for my psp to generate the dxar.pbp file here is the link. i used the upmost link it holds all the files required.
