Sony PSP Motherboard Replacement Guide

My girlfriend is on a streak, or she just knows me really well.  It’s pretty hard to top gifts like a leather Lord of the Rings beer mug and a Dremel, but she manages to do so. For Christmas this past year, she got me a Sony PlayStation Portable (Model PSP-2001, otherwise known as the “slim”).  Given my tinkering nature, there was just one problem.  My PSP, being one of the later slim models, contained a motherboard that, to this point, had been found to be…[Insert ominous music here]…unhackable.

What was a warranty voider to do?  After some research, I had found out how to tell if a PSP is hackable. There is a great forum post over on pspmod.com containing a guide on how to determine the hackability of your PSP.  I confirmed that my PSP contained the thus far unhackable TA-88v3 motherboard. I decided the simplest route would be to purchase a PSP identified as hackable from eBay, and swap out the motherboard with mine.  Upon completion, I would sell the eBay purchased PSP back on eBay with the disclaimer that the motherboard had been replaced.  It was a flawless plan, except that the aforementioned guide required knowing a lot of information about the PSP before purchasing it. I was not looking forward to Q & A sessions with many sellers asking for serial numbers and box codes.

There was, however, a simpler solution.  The guide also mentioned confirmed motherboards in certain limited edition PSPs:

Daxter Limited Edition Pack (TA-85v2/3.80 OFW)(CONFIRMED)
God of War Limited Edition Pack (TA-88v2/3.95 OFW)(CONFIRMED)
Madden 09 Limited Edition Pack (TA-88v2/3.95 OFW & TA-88v3/4.01 OFW)(CONFIRMED)
Star Wars Darth Vader Edition Pack(TA-85v2)
*Note – OFW stands for “Official Firmware”

I decided to go with the TA-85v2 motherboard. Why?  No technical reason.  I just felt that my PSP could use a little dark side with the Star Wars Darth Vader Edition PSP.  I was victorious in my online auction and was ready to swap motherboards.

My Dremel Has a Purpose – Nameless NES Portable

I’ve decided to update the site with a couple of things that have been occupying my time, leading to less frequent posts. I became interested awhile back in homemade portable video game systems thanks to the very talented Ben Heckendorn. For my birthday back in August, I received quite possibly one of the greatest gifts ever: a Dremel.

So I broke out the soldering iron and began working on a portable, handheld, Nintendo Entertainment System that would accept NES cartridges. For the portable community, yes, this is a NOAC (NES-On-A-Chip) build. I haven’t yet named my portable, but work is coming along nicely. When completed, I will post a full build log with pictures and descriptions, and most likely a demo video. For now, here is a picture of the front of the portable (paint finished) with the controls and screen loosely set in for mock-up purposes. Pay no attention to the fact that the controls aren’t seated properly as there’s nothing holding them in.  They’re just set in there for the picture.  Enjoy!

The case is a frankencase combination of Polycase’s AG-85 enclosure, the plastic from an NES controller, and the screen bezel from a PSOne screen.  It took about 7,283 coats of Bondo and sanding, plus some precision painting to get what you see here, but this is indeed handmade.  Check back for more updates as I provide them!
