PSP Pre-release 1.00 Firmware 

Lmao the clicks are error sounds

Wow! It’s interesting how different the sounds are....

The click sounds that played error sound always gets me

Damn, the psp changed drastically from 1 to 1.50

Imagine If the Startup Sound used in this firmware stayed. And then imagine turning on your psp in the middle of night.

My PSP has 1.0 still, bought on launch week in Osaka. Wonder how to update firmware to play some recent games

Woah, This firmware is earlier than firmware 1.0.3 firmware, Sony has released firmware 1.00 as an Network Update Test, so it's not leaked at all. This firmware is only installable on compatible models with a few modifications. If it does not list the minimum firmware requirement of firmware 1.00, then it is NOT compatible. Unfortuanently, this firmware is unstable. PSP-1000 (First): 1.00 PSP-1000 (Legolas): 2.00 PSP-2000: 3.60/3.9x/4.0 PSP-3000: 4.20/5.70/6.30 PSP Go/PSP-N1000: 5.70 PSP-E1000/PSP Street: 6.50/6.60

The old startup is so much better!

"This is the real 1.00, the one that came on Japanese PSPs was actually 1.03." I mean, you're pressing O, so isnt this technically a Japanese PSP as well?

Everything's *ERROR*

Welp i prefer the final build because in here we can hear the error sounds

those sounds are much better than the ones on psp today i hate the sounds today

That's sounds much better than new sound

To think this came out in 2004

can i run games with this firmware? like ridge racer, because i bought a psp 1000 and i want to install this firmware...

The sound when you tap on the screen changed to the error sound

I like the sounds more.

How did you find this firmware?
