PSP Boot Sound?

I seen other PSPs on videos, have like a different sound when they start up?
Exactly how do they do this? :S so odd i think.
lol I got wave files.
if that would do anything.

Wondering about the programs used etc

x-flash I think.
Havn't used it in a long time so I can't remember, Im pretty sure its FlashMod or x-flash

well either that or you can get rid of the opening boot completly with the Harleyg's Custom Firmware, I love it because I hate having to open the annoying UMD drive everytime I start up my psp, but not anymore! but if you do want good Bootsounds, be sure to check out my Ultimate Homebrew Pack, which is in th works as we speak, but you can always download the old version

heres the link

X-flash.

where can I download X flash?

[crait]

psptools.de on the forums page, then go to homebrew and hacks
its in german
or you can go to psp-news.dcemu.co.uk and look a few pages back

or dl the hack pack which comes with it, oh and the new updated version of the hack pack WILL be out tomarrow.

can 2.80 psps bootsound changed

no sorry 2.80 cannot change the boot sound but there most likely will be a downgrader.
