    GP2X Can We Reallocate Our Framebuffers Into The Lower 32 Mbps?

    If you use a kernel module to allocate memory, then you're just doing the same thing as if it were in the upper 32. Your program still won't be able to malloc it or things like that.

    GP2X Jabber's Log-fire

    I think it's referring to a register number 0x808 according to the documentation, but due to how the logic is connected to the address bus, it probably requires shifting the relative address right by 2 bits. memregs32[] is just a reference to the memory mapped registers, and the index gets...

    Maxing Out The Nand?

    If it does prevent it from booting, you should still be able to do a firmware reload off an SD card and fix it. I wouldn't worry too much.

    GP2X Fixed Point Class

    I think a solution is to assume that sqrt always operates on positive numbers... if you're taking a square root of a negative, chances are there's already a problem. Division by zero could return the maximum representable value, and again, it's one of those things you try to avoid anyway.

    Custom Power Suppies

    Yeah, the one thing to be careful with is the linear regulators that usually have a 1.5A or so max... these things essentially drop the voltage by varying resistance, which means they heat up proportional to the voltage drop over the whole range. like... a 6V input, 3V output would burn half of...

    GP2X Model Railway Dcc Throttle

    No, it would be interfaced with in linux exactly as if it were a hardware serial port. Linux handles the driver for USB.

    Is There Anyone Working In A 2-cores Snes Emulator?

    The main speed bottleneck with SNES emulation is rendering graphics... a 10-20MHz chip thrown in the mix might not be a total killer. Besides, I think some super FX games hardly use the SNES's CPU the majority of the time. If the graphics routines get better optimized, plus sound emulation...

    Custom Power Suppies

    It's just that some of the adapters you get are total crap and won't even work properly because the voltage output isn't stable enough, so I could see some people being interested in a homebuilt adapter (provided it's in a decent enclosure and such). Throw a decent sized capacitor across the...

    Batteries - 2500mah Or 2700mah

    Supposedly NiMH and Li-Ion are better suited to fast charging than NiCd, so I wouldn't worry about using it at all.

    Mplayer Source...

    Oh ok. Yeah I think then they're good provided that the code inside mplayer to interface with the kernel module is there.

    GP2X Model Railway Dcc Throttle

    If you have a breakout board, you might consider just buying a USB<->Serial adapter - this will solve both the gp2x sending console text to the output, as well as giving you a standard +-12V serial port voltage, which may be easier to interface depending what you connect it to. The only issue...

    Mplayer Source...

    But if they do not release the source code to everything required to make the exact same mplayer binary they distributed, then they MUST release the non-GPL object files instead to allow re-linking a modified mplayer with whatever they added. Of course, source would be nice, but they legally...

    Questions About The $3 Sd Reader (not Answered On Site)

    I'm sure it works fine with USB mass storage... you have to try really really hard to find something that doesn't.

    GP2X Toolchain Problems

    I think this is the problem: SDL_GP2X: Physical screen = 16192x61424 (ilace = 0) I remember seeing a thread/post with the same thing (or at least something where it found a totally bogus resolution somewhere), but I'm too lazy to search for it.

    2 Usb Mice/mouses At The Same Time?

    This should be possible with linux in general, but I doubt the emulator supports it.

    A Sad Week For Me!

    It wouldn't be impossible to add a password protection capability to U-Boot, but the two problems I can see with it is people might brick their units by attempting the upgrade (or forgetting their password), and that it could still be gotten around by using JTAG. A potential fix for the...

    Weirdest. Error. Ever.

    Is it messed up before linux has started (green screen I believe?), or the whole time? This could help narrow down if it was some startup thing (maybe g_ether loads at boot?) you installed that messed it up.

    Commercial Games Data Protection

    My stance on DRM for things like this, is that if I can't copy it to another SD card, I will not buy it. End of story. I don't care if there's a serial number deal, or even a serial number + name registration combo, or obfuscated data storage techniques. I want to be able to put it on the...

    GP2X Simple Way To Protect Assets?

    You could go farther and add the images to the end of the executable - have an index at the very end... kind of like how self extracting zip files work. In fact, you might even be able to use a normal zip library to read out the data if you append an actual .zip.

    Personally I don't think the dev version is that bad, just might need to use a little creativity making an enclosure for it.
