I use a homebrew firmware for my MP3 player its called rockbox for the iriver ihp140.
Im not a programmer but what they did is very sligtly alter the firmware so when you turn on you can choose to boot the original firmware or choose torun a completely new operating system from its hard drive.
Imagine turning your PSP on and choosing sony firmware for your UMD games or boot a OS from your MS to run homebrew on!
The advantage with that is obvious! but also means only slightly altering the sony firmware.
Maybe there is someone who knows what they are doing should speak to the rockbox folk they have a forum on www.misticriver.net
Somone will finely some day. Alter a firmware for the psp.
I dont know if you would find such a thing here tho.
DCEMU prides itself in being legit. And I pride myself in knowing that Dcemu will be around for a long long time because of that :D
I dont think creating your own firmware is illegal!
Altering sony's though probably is!
But even tho it would be possible to create your own firmware from scratch.
One would almost have to alter sonys firmware to do it within one life time.
To build an entire firmware from scratch and not take anything from sonys firmware. OMG just thinking how genius one would have to be to pull this off and make it work. I dont even think the average genius could do it :p
Thats not to say its impossible. Just that its not likely to ever happen:eek:
Doesn't matter if someone creates their own firmware for 2.0 users, the eboot still has to be signed with the correct digital key (which no one knows)
Wouldnt a brand new firmware have its own eboot?
First of all if somone created there own firmware,
It would most likely be open source and nothing would have to be signed.
You would be able to run anything on it you wanted within the speficitacion tech range that the psp could handle it.
provided that the person that made the firmware made it completely open source of corse.
I think you're missing the point... Sure once you flashed your BIOS with this new firmware, nothing would have to be signed...Quote:

say a firmware is created.....will commercial games still be supported.....the games the require updates to play? idk there will always be a hole in everything BUT hardware changes seem to be the only permanent solution because the community will go thu all this again when 2.5/3.0 whatever its called is released and all the new games require it.
Well be more specific in the future. I dont recall us talking about versions specificly,that was a general firmware question.Thats like asking a question and changing the context of the question after its been answered.Quote:

Yes it would, but it could not be created and implemented from scratch. You would have to alter the PSP firmware which is illegal, i am not sure about flashing that open source firmware to their eeprom being illegal though. As of now, no one has been altering sony's firmware, all that has been popping up is work arounds for running homebrew. Also you would still have to crack the PSP encription for the key because uploading a new homebrew firmware mean that now the homebrew would have to pass the key to umd to allow offical sony discs to play.Quote:

Is there a way to run 1.5 update on 2.0 as if 1.5 is the homebrew app on the UPDATE folder without getting the "you already have updated..." with this kid's info?
like changing what you need to change to make it run as if 1.5 is 2.10 ?
TRY IT :p
let me know results
lol
Bye
I totaly gotta try some of what your smoking:DQuote:

Is there a way to have, for lack of a better word "Dual Operating Systems"? then just remove one and still be able to boot your PSP via the 2nd OS?
:Example: You have a psp with 2.0 on it, you have 1.5 software on a memory card, is it possible to delete the 2.0 software and install the 1.5? Ive read that there is a windows OS that you can view/edit files from your PSP?
lol all the questions and still it seems the same ideas go round and round...
well i really want some 1 to crack 2.0 as im paying £180 for a uk psp and i WANT TO PLAY HOMEBREW ON IT IT SUX is the psp still good without the emulators i really want fifa game on it any 1 played it
Get ready for the most noobish thing ever said. I don't know anything about coding, or anything about much of anything really. But it seems to me that because a 2.0 will read the homebrew when it's labeled as an update, but will not run it because it knows it isn't one, what if there was a way to include something in each 2.0 homebrew that made your PSP think that it was infact an update...
only problem with that is, what if it does indeed see it as an update, and try to install all the files into bios? hehe, getting all your psp system files over-written by the snes emulator files might not be too good... :D
unfortunatly i uploaded 2.0 before i even knew about hombrew so i have no clue how it work or what it does. is there any way to get it to go, infact how do u hack n to the damn thing?
is there any way to beak the consouls main code?then we wont need to worry about updates to come
You guys with the 1.51+ We feel for you. remember us 1.5 useres went through the same thing.
My homebrew story.
Even before the launch day of the psp.
when I was still dreaming of what possibilities this new handheld system could have.
I got to thinking. Damn I thought. I remember a few years ago when I was heavily into emulation. All the fun I had playing chrono trigger, and tenchi and final fantasy 5, See as of then final fantasy 5 hadnt come to the US.
And then I started thinking.
Gee the psp is going to have a 333 mhz processor. lol that what i had in my computer back then. Wouldnt it be awsome if the psp could play all those games I had. As luck would have it I had an old disk backed up with every rom that I used to play back then. To give you an example of what time I left the emulation scene, Neo demiforce had just released his first english patch for radical dreamers. It was only about ten minuets into the game, and then back to japanese. I didnt know that it was compleated untill recently lol.
Then I remembered Zsnes, way back when, had page for downloads and one of the more interesting emulators they had was a super nintendo emulator for a camra. yes you could actuelly play snes games on one of those overly expensive camras :p
And then it hit me, Surely theres people working on an emulator for the psp.
There has to be. I hit up google and found dcemu. (this was before I had my psp and before the US launch date.)
And at that time there where no emulators out for the psp. Just nems hello world . (Whatever happened to Nem anyway :confused: ) But there was all kinds of news and speculation of emulators to Come.
I would visit every day. And finely by the time I got my psp Which was a 1.5.
emulation has hit the scene.
But alas.
1.5 couldnt play homebrew. Only those lucky people with the 1.0's could play.
Every day I would come back and read and research.
And finely this news of somone called Killerx surfaced.
everyone thought he was a fake.
And so did I.
But just like me others where entertained by the idea, that somwhere somone was makeing progress. one step closer to being able to play homebrew on there 1.5 psp's.
Then finely in what seemd like forever. Kxploit was released.
I quickly downloaded tetris. And of corse thought the program was a bunch of bullshit. And started reading the forums ( Heavily)to find out other people where having luck with this thing.
It turns out that the memstick swap had to be done within a five seconed time frame. And me i was so careful not to scratch my psp or smudge it, I was just takeing too long.
Success!!! I was playing tetris on MY PSP!!
Then I think it was one week later. The same incredibly talented person, Brought out the single card exploit. Riding us of the memstick swap forever.
Ever since that time I have been hopelessly adicted to homebrew. I will never leave this scene or the emulation scene ever again
what we need to do is install 1.5 to 2.0 as an update (name it 2.1 but inside is the content from 1.5). period
bye
Very true. And I just can't understand since it has been written so many times, why ppl like drunkelf would say "what we need to do is install 1.5 to 2.0 as an update (name it 2.1 but inside is the content from 1.5). period"Quote:

If you read little bit more (not everything but enough) (like me) in forums, you would know that since 1.51 (I repeat myself from other postings) EVERY program has Sony Signature wich the PSP has to check BEFORE starts running it. Changing lines won't make the signature appear.
(PSP white loading screan appears while the signature is being checked so I don't believe the movie posted in here)
After approvement of the signature, the program gets executed. If it's an update - the update itself starts writing in the flash memmory. I guess the update's signature has higher level of access. The checker is just approving and launching the program.Quote:

That's enough, you can't just start recalibrating your CD/DVD player to match it since you don't even know if it's weird hybrid of CD and DVD and something else.
I am so sorry for you folks but it seems to me that it's time to choose: Sony way or custom way
I choose the custom way, the homebrew, the illegal way. And I will start using those as soon as mass-approved hacked firmware shows up.
- Sony way: Pictures, Games, Movies, Internet
- Custom way: Everything "Sony way" has, exept the most new games + simplified code (smaller, faster) + SEGA + PSPide C++ + Linux.
Easy choide if you ask me.
oh, im sorry, but it does work. download frhed and try it. it shows the psp boot screen and the first update screen, but then it says that the file is corrupt and you have to turn your psp off.Quote:
