where does one get all this 'homebrew' stuff, and is there anything decent, worth downgrading for?

Cabelo · 27-09-2005 10:22pm

If not you'll just upgrade again... AHA!

Have a look on psphacks.net the download section.

There a good few emu's out there - Snes - sega - Nes and many more

lee_baby_simms · 27-09-2005 10:30pm

this downgrader aint workin for me. says i have 2.0 and dont need to update. anyone else have this problem?

RE*AC*TOR · 27-09-2005 10:36pm

what are you doing?

put all the files where you are supposed. open the image viewer. you're screen should go to black with 3 codes (or something like that).

also make sure you have no umd in the drive that might also have a 1.50 update on it.

so anyway take out the battery after about 30 seconds. reboot your psp. run the update.

Willymuncher · 27-09-2005 11:26pm

Woohoo it works! Does anyone know for sure if its still possible to upgrade back to v2? I'd try it but I'm left a little shaken from downgrading and fearing my psp was just going to be left a big plastic brick.

RuggieBear · 27-09-2005 11:27pm

has anyone tried to upgrade again?

TinCool · 28-09-2005 9:13am

This looks interesting. Any other Boardsters try this and have it working ?

rabbitinlights · 28-09-2005 9:20am

Sounds sweet, is this possible on all PSP's? JAP/EU/USA?

Tank Top Fever! · 28-09-2005 9:45am

Mine was never a 1.5, it came as a 1.51, so can I still downgrade

Placebo · 28-09-2005 9:45am

some one try a umd loader.

as far as i know, you need to upgrade to 2.00 to downgrade so it doesnt matter if you have 1.51 or 1.52

ah I'm on 2 now. So is this ok? have you installed it? any homebrew running? I'm just a bit nervous about it ye know

Winters · 28-09-2005 9:53am

It does work perfectly well on all JAP/US/EUR 2.0 PSP's

It uses the toc2rta exploit in order to trick the psp into allowing you to "update" itself to 1.5. Using the toc2rta image exploit it will give you a screen with just some numbers on it, remove the battery and start up your psp. Then go into Games\Memory Stick and run the v1.5 update. It will update your system as far as 99% before giving you an error. Once you get the error, remove the battery and start up your psp again. Then, you just go through the normal setup menu and your psp is at v1.5

RE*AC*TOR · 28-09-2005 9:53am

This is ok. I used it last night. It works.

Also Placebo - I've the fastloaderv8 (ie UMD Emulator) with MetalGearAcid and Virtua Tennis - both work perfectly.

Placebo · 28-09-2005 9:53am

i havent done it yet, il do it tonight

Just goes to show you nothings impossible

As a side note, in terms of locating homebrew and relevent software, will the discussions be allowed and info given, or will it be a strict no no. Speaking as somebody who hasn't tried it, and would like to ask, but also not wanting to annoy master amp.

I'd also fall in to this category, can we discuss this stuff, there's loads I need to know about homebrew

Placebo · 28-09-2005 10:56am

i think emulation is bit of a grey area.
http://forums.qj.net/showthread.php?t=14568

^compatibility list for SNES emu.
Only one i want would be supermario world 2 , since it runs perfectly, amongst a few. Alot of problems with others, emulation scene is far from perfect, snes emulation being at the top of the ladder [not sure about genesis]

some homebrew stuff is intresting, like text readers etc so its still all good.
not to mention the umd loader.s. haha

jcoote · 28-09-2005 11:05am

and of course file managers...anyone know if there is a program that does zip archives on the psp???

Tank Top Fever! · 28-09-2005 2:39pm

Right, so I have the three different things I need, downgrader, eboot, and the photo thingy, and I have a copy of the WAB version changer so I can still play Virtua Tennis and Burnout. I'll let yiz know how I get on in the morning

kaisersose77 · 28-09-2005 4:28pm

Since european psps started at 1.52, what firmware have the ppl who downgraded used? or does it not matter which you pick from - US or japanese?

Im tempted to upgrade to 2.00 and check out the browser but dont think its worth the hassle. Also i saw on forums that ppl have said the browser didnt work for them when to downgraded and upgraded back to 2.00, its more than likely BS seeing as all these forums are infested with 10 yr old americans. Anyone try it?

Tank Top Fever! · 28-09-2005 5:49pm

Lads the weirdest thing happened to me when i did the downgrade. I put the buffer overflow in my photo directory, crashed the psp, checked my version when I switched it back on. It was running on 1.0. Then went to boot up the 1.5 but my file was corrupt. So I tried the 1.5 updater on Lumines, and it worked (exactly as it's described, psp seems to crash, press 0 to fix it.). I now have a completely working 1.5. I played Lumines on it a minute ago.

Burnout won't work unless I update again. I'll put the Wab version changer on it in a minute.

This is brilliant

Placebo · 28-09-2005 7:06pm

ok it worked for me, but after the jiberish showed up it asked wether i wanted to update my 1.00 to 1.52 ? i went with a NO. FYI any.

also umb emulator 8.0c works well, i tried untold legends

- i noticed after update, theres alot of jibberish on my card now, can i delete all this or can i delete the update files ?
that tif file ?

also when i go to game and go to my mem card, i see a file "corrupt data file"

kaisersose77 · 28-09-2005 8:24pm

thats a small sacrafice for 1.50 homebrew

, ah u can get rid of the corrupt data icon by renaming the folders in a certain way (loads of spaces or something) and programs like pspbrew. Do a bit of searching and u'll find out what to do exactly ( i forget want exactly to do).

Placebo · 28-09-2005 8:26pm

oh right, have u tried 2.,00 dumper ? need browser back.

trying this at the moment
http://pspupdates.qj.net/2005/09/lua-psp-os-i-v015-released.html

kaisersose77 · 28-09-2005 8:36pm

If u want to browser the only thing u can do is upgrade again and then have no homebrew. Not possible to have the best of both worlds atm.

Placebo · 28-09-2005 8:38pm

i thought there was a 2.00 firmware dumper for 1.5

jcoote · 28-09-2005 11:14pm

just did it there and backed up 2 games using fast loader..works perfect this is unreal lads!!!:D

Willymuncher · 29-09-2005 5:43am

Anyone know how to do this, I'm using UMD Loader 0.8 and it works great, except for the fact that I want to play Colin Mcrae Rally, it requires 1.52 though, Fastloader 0.7 worked good and let me boot to the UMD without updating to 1.52 and i could play perfectly, but I don't see an option to bypass the update and play on UMD Loader 0.8, is it there? As far as i know Mcrae is pretty large in size, reason for me not creating a backup iso as my memory card would probably be too small.

RE*AC*TOR · 29-09-2005 6:36am

i believe you can use both versions of the falstloader

Placebo · 29-09-2005 7:21am

tried
Lumine
UntoldLegends
Wipe out

all work with UMD emulator 0.8c

coded arms didnt, works with fast loader.
Also tried Notepad for it, works well.

I think i had burnout in the UMD and it said it required 1.52, i think theres a hack for this , hacks for everything

jcoote · 29-09-2005 7:53am

maybe a sticky stating which games work with which emulators...backups of course none of this iso bootlegging ****e
