    Mysterious New Batteries

    Did you see the "charging time" on the battery graphic at the top? For people that are used to quick chargers... ouch! Also, 7h*420mA = 2940mAh assuming 100% efficient charging, which never happens. I'm guessing these won't offer any extra capacity over high end NiMH batteries, but maybe an...

    Idiots Guide To Gp2x External Hard Drive

    I think the USBH pins are used here ("host"), and the D pins are actually routed to the USB2 controller. If you have a MKI unit, it's not even worth connecting the +3.3V line (USB uses 5V and probably not much will run on 3.3) unless you have a voltage step-up converter, but MKII outputs 5V...

    Usb Hub

    If you've got an ohm meter, you could test ones you have and try to pick stuff within 10% (that's a typical tolerance value anyway, though rated tolerance can range from I think 2% to 20%). If you put resistors in series, the resistance adds, so this might be useful if you don't have something...

    GP2X Does The Gp2x Run At 81.2hz?

    Well, I say this because the MKI units have a more sensitive screen, and altering the framerate is one (maybe the only, I don't know a lot about it) thing used to adjust it. If you forced the usage of a particular rate, it might upset some MKI owners. It's always possible GPH could switch to...

    GP2X Does The Gp2x Run At 81.2hz?

    The framerate can change - don't depend on it.

    Usb Hub

    Any drivers needed for a hub should be built in - in fact I don't think it's possible to not include them, since hubs can even be used as part of motherboard hardware, etc. Keep in mind the mouse runs at a lower signalling rate (1.5mbit/sec vs 11?) so it may work alright without the filter.

    Usb Hub

    I'm assuming you have the filter components on the breadboard, but if you don't, that would be good to add.

    GP2X Programming New Gp2x Bootloader

    I might be interested in your MiniDos OS for my Sanyo MBC-55x hobby project (I wrote a BIOS for the old 80's partial IBM compatable) - FreeDOS is somewhat of a memory hog on it, so if your DOS runs in 16 bit and is even marginally compatable with simple programs (nasm, etc), I wouldn't mind...

    GP2X Programming New Gp2x Bootloader

    I bet lots of stuff could be accomplished with linux hacks ala the MMU hack, etc. Making a functional OS is a lot of work, and then getting rid of subtle bugs is even harder. Although even just having a good, capable bootloader would be a good thing, and it never hurts to have options in the...

    Bob & Gp2x Ac Adapters...

    It shouldn't fry your hardware, but I'd worry that 700mA might be too low. Try to aim for at least 1A. It's also really really smart to check the voltage output before you plug it in... some crappy adapters output a much higher voltage when there's no load, and this can be enough to fry the...

    Audio Resume Feature...

    Damn. I guess then you would have to use mencoder or vitualdub, etc, and add in a blank video stream. Maybe ogg files would work better renamed to .avi, since ogg is the same container used for .ogm, which apparently works fine renamed to .avi.

    GP2X How To Use Usb Gadget With Xp And Gp2x 2.0.0

    You probably want to set up samba, then you can mount the computer's shared data onto the gp2x (likely you'd want to make a script to do this).

    Audio Resume Feature...

    I wonder if just renaming it to .avi would be enough to make mplayer deal with it?

    Sd Card Broken

    Just try putting a piece of tape over the whole slot where the slider would have been, or if that doesn't work too well (the reader ends up cutting it, etc), you could try a little bit of glue.

    Gp2x Connected To Internet Via Mobile Phone?

    GSM phones can often be connected to linux machines over usb using cdc-acm. I've had a little success with mine (enough to get the emulated modem interface), but didn't want to actually connect because it gets expensive fast for my plan.

    Interesting Usb Hub..

    I bet it would be trivial to hack it and connect power to the other ports.

    Is It Time Yet?

    This could be another argument for a common input library, as well as ensuring that USB connected joysticks or even more exotic button style input devices could even be backwards supported in apps created prior to their common use. The app would just have to enumerate its different input...

    Is It Time Yet?

    I think the best solution is letting the user customize the controls - something like a standard input library with built in configuration capability (or externally by an associated program) could make this more painless for developers, but I really think the key is letting the user change stuff...

    GP2X Upper Memory Useage, Sound Buffer?

    Write a routine to fill the upper memory with its own addresses, play some sound, check what changed ;)

    GP2X I Cant Program But Hear Me Out

    An interpreted language is where the program you make doesn't end up as actual instructions that run directly on the processor - instead another program (part of the programming language) runs on the processor and then "interprets" your program by performing the actions for it. The advantages...
