    "...for teaching purposes on our games programming courses..." I think it's a safe bet they'll be doing game related programming :-P

    Returning A Defective Gp2x

    Sorry, I was assuming you meant someone on the forums recommended it, and not GPH. My apologies, I just haven't run across an official list of them.

    Returning A Defective Gp2x

    Well, the thing is, some adapters that claim to be 3V actually output a much higher voltage (say, 5-10V) when they're not under any load, and only once a device is powered on does it drop down. This in itself shouldn't be a problem, but if there's any significant capacitor on the adapter...

    Power Supply

    Depending how convenient it is to have the devices plugged in for operation, you might consider a few 8 cell AA chargers with NiMH batteries, but I would worry that the battery contacts in the GP2X might become problematic (some report they can be easily bent, and that's just another thing you...

    GP2X Question On The Snes In General

    SNES sound emulation is a perfect fit for the 2nd processor, if only because there is barely any communication between the main CPU and the sound CPU in the real SNES. Those .SPC SNES music files you download are just the contents of the sound CPU memory, and they play the whole song usually...

    My Gp2x Review

    About .ogm: rumor has it these will play if you rename the file to .avi (probably depends if a supported video codec was used).

    GP2X Random Numbers

    Linux has /dev/random too (or /dev/urandom if you're really paranoid about randomness, but it's not guaranteed to return a value immediately). It won't be as high performance as a built in RNG though, but could be useful for seeding.

    GP2X Vincent Opengl Es 1.1 Implementation

    Even a wireframe engine that does hidden line removal would be fun to program. It could allow for some sweet games even without having good graphics artists, and I bet you could have some complicated shapes and still render at a decent speed. With no textures, it could run well on the 940 also...

    Ext Port Powered Gp2x

    With regards to the power system on the MKII, I'm not sure if it uses the same dc-dc converter as the MKI, but at least on the MKII, there's a 5V output from the chip which goes to the EXT port, whereas on the MKI, it was 3.3V which apparently also was before any converters for other components...

    Commands On Startup

    You could make a script that you can execute from the menu to set it - might be a little easier but still not fully automated. The contents of the script would be like: #!/bin/bash route add default gw 10.1.0.1 Maybe someone else has some better tips.

    GP2X 940-based Ogg Decoding

    I wouldn't think the program would have to sleep at all to interact with the 940 - the operating system won't touch it, and I don't think there would be other threads on the 920 involved.

    Usb Host Bob Schematic

    I thought some of the pins changed, I think I remember the reset pin changed to something else on the MKII.

    GP2X 940-based Ogg Decoding

    I was referring to how the 940's cache/buffer was enabled (that is, for the 940 accessing its 'own' memory), and assumed that was part of the code loaded into the 940. If it had to be done manually in the 920 (and if the sample code doesn't demonstrate), that could cause performance problems.

    GP2X 940-based Ogg Decoding

    I think the mmu hack is only for cases where the 920 accesses the high memory, which shouldn't happen a lot here, except for copying the ogg data to the 940, and copying the decoded audio back (if it works this way, maybe it plays it directly?). It would be more of a thing in the 940 code...

    GP2X 940-based Ogg Decoding

    Make sure the 940 has buffered/cached access to its own memory? It could cause some performance impact on the 920 if it's always hitting memory. Then again, without cache, I don't expect it would be fast enough to decode realtime, but maybe. Also you could try replacing the decoding with some...

    Be careful that you haven't somehow bridged two connections that shouldn't be. If one channel were grounded out, it could still register as being connected, but of course it'd also be connected to ground.

    Looking For The Longest Lasting Batteries For Gp2x.

    NiMH batteries don't have to be fully discharged as often as NiCd, and discharging them fully just for the sake of doing it just adds extra wear to the battery. That said, it's recommended to fully drain NiMH about once every 2-3 months, since they can experience "memory" effects, but nowhere...

    Basic Questions

    You can still copy files with scp if samba/nfs is too much of a pain to set up. Getting ssh to work for scp is a simple thing on all distros I've seen. That said, I'm not sure if the gp2x includes an scp program or not, but one should be able to use the Debian ARM version.

    Headphone Output Promlem

    It's still not something I would expect from a commercial offering, however limited the sales volume may be. It's not hard to rig up a QA test for it after the first bad unit or two are noticed.
