how do I load GNG on my 1.5 psp ? etc

Hehehe

BTW while in the 2.71 firmware XMB, if you choose ISO mode, you can change the mounted iso pressing HOME+L or R (it will cycle through all those in your ISO directory).

Anyway, whatever the mode you have chosen, while in the 2.71 XMB press HOME+SELECT to change your PSP CPUs Speed.

Being in 333 -333/333/166- will be the fastest but drain faster the battery, use that with games that have an inconsistent framerate or some occasional framerate drops (wipeout is a blast in 333).

And yes UMDs work the same as ISOs in the 2.71 firmware, same way to launch them.

I have not found how to change from UMD mode to ISO mode... only how to cycle through ISOs, to change mode i go back to the 1.5 then relaunch devhook... a small hassle considering what the program enables to do

edit:
if you want to launch your homebrews from within the devhook 2.71 firmware:

Edit2:
don t forget to compress your ISOs in CSO format using that for example:
http://www.psp-hacks.com/file/583

devhook will treat them exactly like ISO files, decompress them in real time during loadings at a minimal cost (it s still faster than UMD read) and you can save quite a lot of space on the MS (usualy i have a compression ratio of about 60-70% at level 9)

Edit 3:
If you like emulators, the authors of CPS2 emulator put on their site the beta 3 for their CPS1 emulator:

thanks man !

great piece of software.

Last I heard you couldn't downgrade the firmware. Are you still able to do that? What about on a 2.80?

2.80 and 2.81 you're screwed for the moment i think.

I downgraded my 2.71 to a 1.5, and i can switch it between the two now. lol

awesome etc.

got gng working now which works on a 2.71 fw

Well shit. I had my original set at 2.5 firmware but the screen just stopped coming on for... well, no apparent reason. Sent it in to Sony and voila, I get back another unit with 2.80 on it. Damn...

cool, i might have to get those rom dumps off you duder.

thanks for your help, i now have a couple isos running off the stick.. I'm still not sure how to load gng off the umd as i dont want to use the iso of it. no point if i own it..

I was getting confused because sometimes it'd just dump me to the xmb menu again

but I am correct in saying it'll boot my gng umd too right? I guess so.. lets try it kekeke

Booting from UMD:

1. At the devhook menu,choose UMD select.
2. Select 'UMD Disc'.
3. Next,go to 'UMD MOUNT' and choose 'UMD Disc'
4. Under 'UMD VERSION' select '2.xx->2.00'.
5. Choose '2.71' under 'FIRMWARE'.
6. Go to 'BOOT SELECT' and choose 'reboot XMB'.
7. Hit 'START'.

That should do the trick.

B-

yeah i worked it out eventually.. pretty sweet tool, i love how you can switch isos on the fly
