    News from booboo:

    First and foremost: sorry for being so hard to get in touch with lately. We've been in defcon 1 for the last week at work preparing a demo for the current project (OMAP3530 based) which is crucial to the future of the company, so I had reduced my daily routine to sleep-eat-work-sleep. My inbox is exploding.

    Sweetlimre commented on having a writable home directory (see interview). If I recall correctly, I wrote about this already. The main application executed by busybox's init process is responsible for this. At this stage in the boot process no HOME environment variable has been set. I could easily modify busybox's init to set it to "/usr/local/home", but I felt it's better to stick to a vanilla busybox as much as possible. Oh, wait: maybe if (as I recommended) the main menu application is using exec() to launch emus/apps things are not so simple. Need some input from devs here, and if the only solution is to modify busybox's init, so be it.

    Regarding the modified buildroot I'm using, as he requested it's now available for download at the google code project page. I hadn't published it before just because I could not find time to fix all the dirty hacks I used, which resulted in a partially manual build. I'll be glad to add anything developers suggest. Just send me the buildroot recipe. I would really like to stay away from OpenEmbedded. I have to use it for the OMAP3530 and IMHO it is way overengineered.

    Some good news on the Ingenic front: the Qi-Hardware guys have managed to get Ingenic to release their kernel development trees DAILY. This means immediate access to any useful fix they make. There are 2.6.24.3 and 2.6.27 branches, and I'm working on porting the A320 support code to the later, mostly to see if it helps somehow with the USB/DMA and SD/MMC standing bugs. Note that in the case of embedded devices like the A320 I don't think that newer kernel is necessarily better.

    Regarding the Gemei x760+ things are going slower than expected. I dumped the hardware initialization .DL from NAND flash and disassembled it, only to discover I was looking in the wrong place. Let me explain:

    When the JZ4740 boots a piece of code called the IPL (Initial Program Loader) is executed from ROM. Depending on the state of some pins this code either enters USB boot mode or boots from NOR or NAND flash. In the A320 we can only choose to enter USB boot mode or boot from NAND. The IPL only supports 512 and 2048 page size NAND, so despite the fact that the NAND chip in the A320 has a 4096 page size it is handled by the IPL as if it was 2048.

    The IPL reads the four first pages (8KB total) of NAND into the instruction cache (because the SDRAM is not yet available). This is called the SPL (secondary program loader) and its purpose is to do a basic hardware initialization, most notably making the SDRAM available, and load the system loader from NAND. The A320 SPL also handles the NAND as if it was 2048.

    In the original firmware the SDL is stored in the first 8KB of the first NAND block (0x00000-0x3FFFF). It loads the system loader from 0x50000-0xBFFFF. Before loading the operating system the A320 system loader does something interesting: it loads from 0x40000-0x4FFFF a piece of code that I call the hardware initialization DL. It is a dynamic linked object code chunk that does board-specific hardware initialization: GPIO, LCD, etc. This is the interesting stuff. In both the older and newer A320 the LCD initialization code was reverse engineered from this DL.

    However, the x760+ LCD initialization seems to be mostly done by the system loader itself. It stil loads the DL and uses it for some GPIO initialization that is also related to the LCD controller, but not much more. The DL does contain a large LCD register initialization code routine, but it is unused (and I lost a lot of time reverse engineering it).

    Since the system loader code is much larger (~260KB) than the DL code (~10KB), it's gonna take some time to reverse engineer the LCD handling code. Note also that I had already reverse engineered the A320 DL code and that helped a lot, but the system loader is unexplored territory.

    Sony announced a March release for Gran Turismo 5 at Tokyo Game Show last week, a release window that was specifically targeted for the Japanese market. However, don't expect a surprise 2009 release (sorry Amazon!). "I don't think it's going to be that different for US and Europe," Polyphony Digital head Kazunori Yamauchi told journalists at a GT5 event last week. "Marketing is still discussing their issues," which is the reason why a specific date hasn't been pegged yet for those markets.

    Yamauchi then went on to list a befuddling list of features that should ship on the disc next year. GT Mode will return with all the features of classic GT games, like the garage, the car dealer, the tuning shop, and license tests. However, more exciting are the new features, such as a brand-new physics model that includes damage and deformation for all "normal" cars. Hybrid and electric cars are going to be added to the livery, too, with over 950 cars available on the disc. There will also be over 70 variations of over 20 locations to race through.

    The online features have been expanded to include both text and voice chat, with support for lobbies and private rooms. There will be online photo albums and online replay albums as well; with the ability to export replays to YouTube. Gran Turismo TV, the video service introduced in Gran Turismo 5 Prologue will also be expanded with a brand new UI, progressive downloading (so you can watch the video content while it downloads), and the ability to export these videos to PSP. While this may seem like the kitchen sink of features, Yamauchi teased, "we have much more planned."

    Considering it's been five years since the release of Gran Turismo 4 on PS2, fans of the franchise are expecting only the best, if not more.

    The DSI has been out a while now and a few features like facebook and better web browser give it a plus over the DS lite and the DSI Ware Store is a small thumbs up too, amazingly the homebrew scene came up with the best release so far and thats a quality GBA Emulator for the DSI (via Iplayer), which brings me to the question, How Many of you would buy a DSI out of those who so far have refrained ?

    Just interested if any of you are getting a PSPGo and indeed whats selling it to you.

    If you arent interested and are thinking of opting to go with say a PSP3000 for a new console, what would make you change your mind and buy a PSPgo.

    Im sure if there was a Custom Firmware for the PSPgo that would be a big thumps up to selling some PSPGos in the Homebrew Community

    So Anyone Getting a PSP Go ?

    The PS3 much like the PS2 when released brought a new video media to the world, Blue Ray for PS3 and DVD for PS2, both consoles at release date were powerful for their time, the PS2 had backwards compatability with PS1, the PS3 did have the same with PS2 but after a few revisions lost that.

    Widespread piracy was rampant on the PS2 and indeed the PS1 but that didnt cause the consoles to suffer, infact it most likely helped both become the mega sellers they are today.

    So why isnt the PS3 the Mega Seller, what did Sony do and are still doing wrong ?

    You know that UMD-to-PSP Go conversion program? Ain't gonna happen. The "good will" program that would have provided free (or at least heavily discounted) digital copies of games already purchased on UMD discs has been scrapped. A spokesman for SCEA said, "We were evaluating a UMD conversion program, but due to legal and technical reasons we will not be offering the program at this time." Adding insult to injury, the PSP Go Rewards program offering 3 free games to European UMD owners will not be offered in the US. That's the bad news. The not so bad news is that 16,000 pieces of digital content will be available for the US PSP Go launch on October 1st. These include 225 downloadable games (full PSP titles, PSN exclusives, UMD legacy titles, and Minis), 2,300 films, and 13,300 television episodes. Still, not quite the "at least 300" digital games we were expecting. So US PSP owners, still planning to "upgrade?"

    Poor Zipit. As a $149.99 instant messenger client nobody got particularly excited about you. Even now, as a $38 IM client you aren't exactly in high demand -- but as a $38 portable Linux machine, well, that's another story altogether. The machines have been tweaked before, but the latest and greatest is this hack from Hunter Davis, who can turn a virgin Zipit Z2 into a full-featured Linux machine in under five minutes, as shown in the video below. To do the same all you need is Hunter's hacked firmware and a microSD card to throw it onto. Once completely tweaked you'll get full mouse support, WiFi connectivity, and even audio output so that you can rock some tunes on the go -- though the command-line interface won't make it the most compelling PMP ever. With only a 300MHz processor and 32MB of RAM we wouldn't go compiling our COMP-SCI 101 homework on here, but this little firmware refresh certainly makes for a tastier experience than before.

    At last, Sony's other worst-kept secret, the UMD-less PSP Go, is working its way through retail channels this week. The device itself is a marked improvement, but of course that's not the whole story. In many ways antithetical to the hype surrounding the PlayStation 3 Slim, the debut of the Go has been marred by some pretty downtrodden decisions on Sony's part, most notably the $250 price tag, an utter lack of compatibility with any previous PSP accessories, and no UMD conversion program. Will newcomers flock to the system? Will veterans upgrade? Read on for our full impressions!
