PSP 2.6 to 1.5 DownGrader

Hey all

For months, PSP owners, with a firmware higher than 2.01 have had to use the GTA loader to run homebrew software and emulators on their psp. That said, the best of the homebrew still didnt run, as it required an original 1.5 firmware. This weekend will go down in PSP history, as the first succesful DowanGrader for 2.5 and 2.6 firmware psp's....

I never thought I'd see this day

This is pretty damned amazing.
I guess Sony will start making 2.7 firmware a requirement to run new games...

Has anyone heard anything about Undilluted Platinum lately? I know it exists and I've seen a video of it installed working properly. Has anyone here actually purchased or seen one? I was planning on buying it just for research, but money got tight here this week and it's just to expensive right now.

 

There's been several members from the pspupdates forum who have it. Installation I've heard is a bitch, and is uncompatible with thr TA-82 psp's

It seems quite cool, although not that much different than a 1.5 un modded psp...yet..

Personally, with the advent of this newest downgrader, i think it's hindered the UP's sales quite a bit

no

the downgradeer freeze 1/2 psp!!

it is still a beta!!

 

Right it is just a beta right now, but there will be a finished working product in the near future. At least they are on the right track. Many people never thought that they would get this far.

UP may have had its thunder stolen by this downgrader, but downgraders aren't really a replacement for a chip that allows custom firmware. Can't wait til I can actually try my hand at installing one.

 

I bloody upgraded to 2.71 to get the LocoRoco demo as 2.6+ seemed a dead duck... oh well, I would rather chip it personally.

 

I just can't see paying a 100 bucks on something that could be softmodded.

 

Worked very well for me, earlier release's of the downgrader indeed created "bricked" systems, but the latest release has proven to be the most stable, with roughly 98% of all users reporting success

Its the most nerve racking 4 minutes of my life

So what emulation is the PSP capable of? I remember reading SNES and Megadrive games run mostly full speed but what about gameboy/gameboy advance/neogeo?

 

Same here OH:

 

Emulation is quite good, considering its a portable. To my knoweldge, the psp is capable of emulating(very well) these following consoles

NES
SNES
GameGear
SMS
MegaDrive
Gameboy/Color
Neo Geo
Neo Geo CD
Turbo Grafx 16
Lynx
NeoGeo Pocket
Wonderswan
Dreamcast VMU
Commodore 64
Atari 400/800
Colecovison
Atari 2600
Several early computers
Doom
Quake
Quake 2
Lua port of starcraft

There's also some others that dont quite work flawlessly, although there still a work in progress

Playstation 1
N64
Jaguar


thats, just the emulators themselves, there's also things like PSPOffice, and IRShell

Sorry bumping an "old" thread but what I wanna know is if the emulation of genesis/snes on 1.5 psp is the same as in 2.01?

I'm asking this 'cause I've tried some games on psp gen emu(I think it was some Gens "spinoff") and it was slow and the music sucked. The same was for the snes emulator. I've overclocked to 333MHz but with no good results.

And I think for 2.5/2.6 PSPs, I think GTA is still necessary for the exploit.

 

Ryan, can you gimme that Doom and Quake console?

 

The site from which i got the downloads for doom/quake is currently down, ill post the links when its back up...


Haljordan.....i assume your a 2.01?.,....my recomendation is, upgrade to 2.6, then run the new downgrader.....you'll be at 1.5,Honestly, SNES emulation ran slow on 2.6, and 1.5 improves it quite a bit, but its still a bit from perfect. Genisis emulation however, has been amazing, even on 2.6 using gta, it was quite good. I used DGEN 0.70 for 2.6 emulation, and it was quite good. on 1.5 however, its bloody perfect

You'll notice a fair step up in useability and speed from the gta loader to 1.5


Ryan

 

Yep, mine is a 2.01 which I got "cheap as hell" on brazilian ebay. I'll keep an eye on pspupdates' forum for upgrading-2-downgrading

Btw, I ran sonic 1 on dgen on 2.01 and sound was skipping too much. I've tried all kinds of configuration but never got lucky.

Thanks for the info.

 

I've found that dgen on anything above 2.01 has weird sound, though 1.5 seems to fix it


Note, they've also released a 1.5 to 1.00 downgrader, which will eventually allow for a custom firmware to be used, much like the UP's epison bios

RyanGamerGoneGrazy:

I hope you can help me..I really got interested in downgrading my psp but what I wanna know is, will it be able to use some features of the newer firmware?

Checking Sony' site, they only show 2.71 to download, is there any reliable site with that FW?

 

simply put, if you downgrade to 1.5, you can then, via devhook, or some homebrew, have every feature that the later firmwares have. If that still bothers you, and you wantt say, firmware2.6, then download devhook, and emulate it that way, in conclusion, anything that has been done in a higher firmware, has already been done in 1.5


Msn, or pm me if you want to downgrade, or need help

Hey Guys

I have one of the original 1.00 models. It was upgraded to 2.00 when I added Tiger Woods. I'm going to sell it and get the DS as I talked about on another thread.

Question: Is it better to downgrade to 1.5 or all the way to 1.0? Is there anything special about having an original 1.00 model?
