PSP Custom Firmware Thread

That probably wouldn't be enough either.

Something like the ChickHen exploit currently possible on later 2000s and 3000s is enough for a homebrew enabler, but not enough for a full custom firmware flash. The pre-IPL encryption on the new motherboards needs to be cracked before the newer hardware truly falls. At least for the 2000s and 3000s. I honestly don't know what the deal would be with a PSP Go.

i figured that one of those downloads would be the kind of 'loophole' way in to running custom firmware like that original tiff image exploit or whatever. i have no idea how the stuff works, or what i'm talking about, i just assume that when a chink in the armor's found, maybe it would be something that sony couldn't just patch up before it gets distributed all over.

I'm not sure what you're trying to say.

In brief, a game software exploit works this way:
1) Start a game and load a special hacked save file to trigger the exploit,
2) Use the exploit to run unsigned applications (such as a homebrew enabler or custom firmware installer)
3) Install custom firmware over the official firmware, effectively cracking the PSP.

A PSP Go is trickier because, lacking the UMD drive, software comes exclusively from the Playstation Network. If someone actually discovers, develops, and releases a working exploit for a PSN-available game, Sony will pull the game from PSN, have it patched to kill the exploit, and at some point, re-release a new version of that game.

That it's possible to download an ISO of the original (still exploitable) version of the game from some torrent site is irrelevant, because the uncracked PSP won't be able to launch that ISO, and thus, wouldn't be able to execute the exploit that would enable him to crack his PSP. A PSP needs to be cracked before that kind of ISO can be launched.

The lifespan of a hypothetical PSP Go game software exploit is the exact length between when the exploit is released, and when the game gets pulled from the PSN by Sony. In other words, the lifespan will be so ridiculously short, that no one's really going to waste time even pursuing the development of that kind of exploit.

Ah, I totally see now. I was thinking in terms of using an iso that the go wouldn't be able to run in the first place. thanks for the explanation.

Oh of course it would only be the first step to cracking the Go. But it's really the only feasible option at this point, unless someone makes a new Pandora (or someone inside Sony leaks the method for service mode on newer PSP models).

Curiously, I was reading about a dissected PSP Go, and it seems like the battery is separate and removeable, with a bit of effort. I figured that for ultimate security, they had basically integrated the battery into the hardware, effectively making it almost impossible to remove and swap out for a Pandora/service mode battery.

But they didn't. Sure, you'd need to open up the casing yourself, but inside is a fairly standard battery. Just another last minute half-measure, really.

Most likely Sony is still using a jigkick battery for PSP service mode. Which means that if somehow that gets leaked or reverse engineered...

Yep. It all goes back to the new encrypted pre-IPL in use by newer PSP hardware.
That encryption needs to fall before anything significant can happen.

It's been so quiet on the front, I hope the later 2000 and the 3000 units are still being worked on. :(

Yeah, also the fact that I don't really know where I should look for up to date info about that (other than this thread and maxconsoles forums) kinda bugs me.

Someone's picked up an older version of the SNES emu (the last version released by rukka) for the PSP and seems to be whipping up miracles. This is a very preliminary "draft" of what he plans on accomplishing, but it looks like substantial framerate increases on previously troublesome games have been achieved already. It's still based on the older 1.42 SNES9x core, but he plans on updating it to the 1.51 SNES9x core as he continues to work on it. He says that there's still LOTS of room for improvement.

Via : RetroEmu

So I have been working on this for a bit tonight (I am really sick atm )

However I did feel well enough to at least get out of bed for a few hours and wrap up Snes9X Euphoria for a release.
It is based off the last version of Snes9xTyl by rukka.

My main objective for this version was speed. A lot more can still be done to optimize the emulator and get more speed, but for now (given my health) this will have to do

The only game I have tested with my version is Kirby Super Star, which I know had terrible FPS with other Snes9X releases (usually < 30Fps)

With my build, using the following settings, Kirby Super Star runs @ a minimum of 44Fps and a max of 60fps with the usual fps being 50fps.

Settings :

Renderer : PSP Accelerated
FrameSkip : 3

This does not generate a jerky experience, it finally feels playable

Other testing :

Donkey Kong Country : Same settings as above :
Min FPS : 58
Max FPS : 60

The speedups should be global, every game should be a lot faster now

Future :

I plan on improving speed more, improving stability and applying the changes from Snes9X1.51 to Snes9X euphoria also (which is running off the 1.42 code base)

I hope you enjoy this release and if you have any bugs please post them in the : Snes9X Euphoria - Official Forum

There seems to be some graphical bugs in the menus in Kirby Super Star (and maybe other games), these will be fixed in later revisions.

Thanks and I hope you enjoy the release

Thanks

I have only scratched the surface, there is a hell of a lot more that can and will be done to speed up this emulator and make it more stable.

Just give me time

star fox starts up plays with only pink screen at 49 fps
with mario kart set at psp accel + approx, soft. runs good bounces from 45 to 60 fps
killer instinct now runs full 60 fps
super mario world 2 is almost full speed now 45-55 fps
mortal kombat 3 runs at a full 60fps
mortal kombat 2 when picking fighter screen goes black but when fighting full 60 fps
primal rage runs full 60 fps

5.50 GEN-C out
xgen-installer-for-5-50gen-c_1255907733.zip
27MB

Games above 5.51 supported.
Games with protection (Soul Calibur) supported
Games and demos (Peace Walker) from PSN supported.

IRshell currently not working (WIP)
480x272 video playback bug still exists
Memory stick speed boost not implemented (WIP)
What bug is this? Is there really a problem with playback of videos of this size in the /VIDEO folder? Or is just the stuff in the old video folders that no one uses (or should use..) anymore?

You mean Disgaea 2? Disgaea PSN runs perfectly fine on 5.03 without any modifications.


The PSN download of Disgaea 1? Because I know the UMD version is later (being released last year), but the PSN version was released a couple of weeks back in general Sony will up the versions requirements if they want.

Yes, that's what I said (I got it on day 1 of sale, with Gurumin, both work with no modifications on 5.03).
Most legacy-titles are put on PSN as is (straight ISO, same FW requirements as original UMD). "Upping" the requirements will only happen for titles that get resubmitted (like Daxter, which will have some performance improvements for PSN).

^^^ Is there any way to get that SNES emu to run on 1.5? I still haven't found a GOOD simple noob guide for custom firmware.

Probably not, considering that the 1.50 kernel was effectively dropped like 2 or 3 years ago.
It's time to leave the ghetto, dude.

I think I'll pass. Seems like Team Gen will be releasing a bugfix version soon.

There are plenty of easy to follow guides out there.
There's simple, and then there's *simple*

You're the one with Gen-C. Give it a shot.

I'm not very technically minded when it comes to this stuff tbh, I thought maybe I could get my PSN acc banned or something, I'll give a shot then if it's ok to do so.

I tried, it kept trying to access and went in a continuous loop. No luck for me.

Curious. They must be testing a new work-around. Shame it doesn't defeat direct PSN access. But perhaps it might, as I understand it, this MediaGo development is just a beta version for now.

I hear that they're working on porting Dark-Alex's memory stick speed up hacks as well.

Do other games work ?, did you go into the recovery menu and change it to an iso driver/loader instead of UMD ?

hmm ... so i toggle off my wlan switch last night, so not sure it's this CFW or not ..but now my wifi connection to my router is timing out.

it can scan and see it though...just the key exchange part keeps repeating. sigh.

hey on that note ... ps3 slim ... i used to be able to use my ps3 phat as a AP ..while cabled. but now it's not showing up when my psp scans for it. werid.

i can scan from the ps3 and detect my router/AP though.

is there a setting on the ps3 you have to toggle to make it act as a AP for yr psp ..or did they take that out of the slim? seems weird ...

...Because it isn't supposed to?

It isn't fixing that aspect (unless you mean connecting it to the "store" through PC/Media Go, in which case that's a bug and you need to get someone to fix that shit for you) of wifi connecting to the store. Just FYI.

I'm going to hold off until the bugs get ironed out.

Still would love to see a 6.xx CFW just for the updates to the PSX emulator (or even an update to popsloader for the 6.xx files). Mainly just to see if FF8 will finally run right.

Whelp, installed GEN-C, and Gran Turismo runs, but crashes after the intro video, as soon as it prepares to write a save file.

Looks like I'll have to wait a bit longer :/

Wifi with WPA also doesn't connect, therefore no PlayStation Store either. Tried one of my CSOs with Sony NP9660 driver and it worked fine.

Looks like Team Gen's pulled the update. They're advising people to wait for the fixed version, due out soon.
 
Sorry, but CFW seems completely fucked at this point. Without DA the scene is clumsy, slow and seemingly completely stuck in place.

I would pay DA to come back at this point, since I can't give all the benefits of CFW up but the future looks increasingly bleak without him.

Seems like people are conveniently forgetting that some of Dark Alex's custom firmwares had 6-7 revisions/bugfixes as well.

*rolls eyes*
 
Except his new firmwares normally came with everything from the latest Sony ones, with some minor glitches quickly fixed within 24 hours.

Gen remains stuck in sub 6.0 firmware, barely inching forwards and when it does its buggy and not as good as the firmware we've had for years now. The only reason this firmware is even coming out is because Yoshihiro came back on board with his game decryption stuff to build into their current setup. That means theyve made no actual progress in bringing anything over from 6.0 at all.

Its back to CFW being jury-rigged to just about letting you play the latest games as compared to the glory age of every single new OFW feature being featured within like 48 hours of release.

I like to pretend DA is sitting in his room, surrounded by a huge cluster of machines slowly cracking away at the PS3, 3000 and GO. Him biding his time, with a little countdown clock ticking away until the release of mother of all releases.

:lol

See, this is why dreams are better than real life.

Well, weren't most of those just minor updates though? It's not like the psp could explode in your face if you didn't update, iirc :)

Edit: To me, minor is when maybe one or two minor functions stop working or are a bit glitchy. Major is when you need to go out & buy new hardware due to bricking or something.
