The original PSP may be old news but there is an interesting relic of a website (translated) dedicated to the reverse engineering of a PSP (and exploring Saturn?). To determine the true capabilities of the PSP they desoldered most of the ball grid array chips and then hand soldered 157 jumper wires to allow for direct memory access. In later pictures it shows the PSP hooked up to external hardware for on the fly memory modification. Unfortunately the details are sparse and it doesn’t appear as if they will be updated anytime soon because the website has been “deleted and freezed because of spam. may ineffaceable curse prevail on the spammers.” Still this doesn’t detract too much some very impressive soldering.

[TokyoDrift] built an adapter that allows you to connect a PlayStation 2 controller to a PlayStation Portable. It’s a bit different from similar hacks as this adapter doesn’t require any hardware alteration to the PSP or the controller. To do so, a plug-in is used on the PSP firmware side of things. The adapter then makes use of video out and PS2 controller extension cables, along with an ATmega8 microcontroller to handle the signals between the two devices. We posted a picture of the guts because we like that king of thing but the finished project is nicely housed inside of a project box. See for yourself in the video after the break.

[Christian Doran] wanted some blinky goodness to go along with the tunes on his PSP. He built a VU meter circuit around a couple of LM324 op-amp chips and fit it into the UMD space on the back of the PSP. Using surface mount LEDs and some fine wire he lined up a string of indicator lights round the circle on the clear UMD cover. As you can see in the video after the break, the back of the case now pulses along with the music.

[Christian] notes that building the VU circuit around an LM3915 would have been much easier but he’s working with what he has on hand. Looks like he achieve the effect he was after. If you want to learn a bit more about how the op-amps work, take a look at the tutorial from our links post.

[JoblessPunk] recently finished his what-a-psp-should-be mod. He’s internalized a camera and added a switch in the body to toggle between using the camera or using the USB port. There’s an additional analog stick, and added charging functionality via the USB port. He’s also packed in an additional 32 GB of flash memory. The device is of course running custom firmware which facilitates the ubiquitous flock of emulators and homebrew apps.

We agree that the original PSP is a pretty powerful handheld that never saw a full realization of its potential.  With the impending release of the next generation PSP Go we hope the price and availability of the older units leads to more mods of this sort. Check out the video after the break.

Here’s a well made video from [JoblessPunk] detailing his work. The first half is propaganda to help find partners for a future commercial venture involving these mods.  The second half shows-off the new features, connectors, control, etc. Try to resist the urge to strangle when you get 25 seconds into the video; it’s all uphill from there.

Not due to be released until the beginning of October, a PSP Go demo unit (shipped to G4TV) has already earned itself a teardown from [iFixit]. Among what was discovered:

- Once a few screws are removed, the battery is user replaceable (as-in: no soldering iron required)

- Wireless connectivity is only supplied through a 802.11b chip (no update to ‘n’, or even ‘g’, by Sony)

- Almost all chips are EMI-shielded (making them a bit more annoying to get to)

With a cheaper version of the PS3 ready to hit shelves, one can only wonder whether the relatively high price tag on this new PSP is worth it.

Update: It seems as though no party involved wanted the info leaked this early, which explains why the video and picture gallaries (up courtesy of Google) have been removed.

Update 2: The article (linked above) and video are now available. An explanation on why Sony had them remove the items for quite some time (plus some repair manuals) was posted by iFixit.

[Folklord36] on the Acidmods.com forums has been working on a PSP laptop that we think gives the PSP GO a run for it’s money. Sure it may be a bit bulkier but it has a full keyboard, thanks to an Xbox chat pad. The original psp is on the bottom. The screen and speakers have been moved to the top. He says there are still a lot of things that need to be finished, but this is pretty impressive already.

Engadget has video from the June 2009 episode of Qore that shows the new PSP Go. It has a slide out gamepad, 16GB internal storage, bluetooth, and a memory slot of some sort. We’re naturally curious about its potential as a homebrew platform. Will Sony take the mature route they did with the PS3 and let you run Linux or will they continue the firmware arms race the PSP is known for? We’ll be hearing more about this platform at E3 next week.

PSP firmware 5.03 has been hacked by Team Typhoon. This allows you to run custom code on the PSP by taking advantage of the tiff exploit. You’ll have to wait to download the hack though, they haven’t released it yet. This means those of you still on 5.02 or still using the little blue tool will be able to upgrade soon.

[TokyoDrift] has added mouse support to his PSP. He’s using a microcontroller to interpret for the PSP, through the serial port. You can see in the video above that this provides a functional mouse control, especially useful for first person shooter style games. He’s got lots of details as well as schematics available in the forum posts. We’ve seen other controllers added to the PSP, but this is the first time we’ve seen a mouse.

[Avi] sent in his PSP as a status monitor hack(zip). He’s using Lua on the PSP, so you have to install LuaPlayer. The computer side is written in python, so it should be cross platform. Last time we saw a psp as an extra monitor, it had more capabilities, but it was limited to Windows. You’ll find the Lua script as well as the python in the zip file. It’s a nice use for an extra psp.

Gizmodo has done us all a favor by wading through many forum posts and condensing them into a handy guide to installing Ubuntu on your Playstation 3. It covers some of the caveats of going this route. You have to backup all of your game data before starting since the system repartitions the drive. Ubuntu installs without any problem, but because the cell processor is a PowerPC architecture it means not everything has been ported to it. There are a few things you need to install to get the Sixaxis controller to be recognized as a joystick. Super Nintendo emulator SNES9X is available and works, mostly. It doesn’t support fullscreen and cries if you reconfigure the buttons.

Supporting developers through alternate operating systems isn’t new to Sony. With the original Playstation, they released Net Yaroze, a consumer grade dev kit. The Playstation 2 was the first time they officially supported Linux on a game console (our first Linux machine). The ground breaking thing about the Playstation 3 was bundling in Linux support with every single console; no specialized hardware needed. Unfortunately they’re not near as open with the PSP.

[matiaz] has released an exploit which allows homebrew on the PSP3000. It takes advantage of a vulnerability when loading save games on a game called GripShift. You can see the PSP running unsigned code in the video.

Peripheral manufacturer Datel has been hard at work attempting to crack the PSP 3000 since its release. They’ve developed the Lite Blue Tool battery to force the PSP into service mode so hackers can run any arbitrary code they want. According to MaxConsole, Datel performed a silicon level investigation of the PSP’s chips to determine how to break into service mode. This means they decapsulated the the chips and reverse engineered any cryptographic protections. We’d love to hear exactly what chips were being used since some are fundamentally flawed.

Silicon hacking has always been a favorite topic of ours and we suggest you check out [Chris Tarnovsky]‘s decapsulation technique to learn more about it.

[foo] sent in this amazingly well done mod to add an SNES controller to a PSP. He was contacted with a request to mod a PSP for someone who had limited use of one hand. The PSP controls were too difficult for her, but miraculously, she could play an SNES controller well. The quality of the mod is very nice. [foo] has added a port on the back that the controller plugs into. Other than the port on the back, the PSP looks completely stock and functions fine. When plugged in, the cable and plug act as a stand for the PSP too. Check out the video after the break for more.

[alien x] has posted this peculiar hack for a PSP. He has gutted and splayed the PSP spreading its insides neatly and mounting them on a plexiglass back. Everything is easily accessible and ready to tinker with. It may not fit in your pocket, but adding mods and experimenting with ideas should be much easier like this. It looks pretty cool too, we want one for our office wall. That could be possible too, he’s selling it.
