    I would love to know why it was removed, as it doesn't seem like they're going to foster much of a developer community if they remove valuable information like that! Also, although you say it should be safe because GPH use it in their build of SDL, don't forget that their SDL libraries will...

    GP2X Flickering Screen With 2.0.0 Firmware

    Well, hopefully I'm right, and it will work. Your suggestion also sounds a lot better than what I was thinking of. I was thinking that one might change the polarity setting at the program start, and restore it on exit, but of course, it's much better (and safer) to look at what it's set to and...

    GP2X Flickering Screen With 2.0.0 Firmware

    Some of the code I've seen waits for the edge on the VSYNC signal, rather than looking specifically for the change to low, so the worst-case scenario is that you miss the 'flyback' time. From a quick scan through the new sources, the change appears to be in /drivers/video/mmsp2fb.c. The call to...

    Acc. Sdl? Silly Question

    As I might have mentioned in another thread, I'm toying with the idea of writing a kernel module that will provide memory amd IRQ management routines for the upper 32MB, and I think something that would be good to add would be an interface which can return the physical location of...

    Drm Restricted Commercial Games

    Well, we've asked, and Craig has only answered selectively, so at this stage I think we're pretty much free to speculate. It's not like you've exactly been constructive in your comments anyway (have you read any of the other threads which led to the creation of this one?)

    Group Game Project

    You should try running the 'Pinball' series of games (you can download them starting from http://www.abandonia.com/games/41/PinballDreams) and see what you think. I'm in the camp that thinks pinball is probably the most boring game in the world, but I really loved these games on my A1200, as I...

    Keyboard Info

    I didn't even cop onto that (/dev/GPIO) in your message, I'd never noticed that you could access the GPIO like that, but I'm sure there is a speed penalty. I'll have to look into this now, as it could be useful for quick and dirty programs. The format looks a little bit like it could well be...

    ? Compiling With Gcc 4.x

    Hi, At the moment, static linking is the easiest option, if you don't mind the size of the resulting binaries. The version of GCC seems to have no impact on the low-level stuff like syscalls (there's an interesting discussion of this in one of the recent demo programming topics.) There are a...

    GP2X Does The New 2.0 Firmware Ease Dev At All?

    And thanks also for your build of GDB, it was a huge help when I started learning to code for the GP2X!

    Keyboard Info

    Have you seen this? The notation used on that page is [GPIO register][bit], i.e. for the left shoulder button, C10 is GPIO register C, bit 10. The controls are designated active low, so the bits for each control are normally set to 1, and when the appropriate button is pressed, the bit is reset...

    Drm Restricted Commercial Games

    Sorry, I thought you meant when you install the game, so my objection was that there might be any number of reasons why you might need to re-install and not have access to the server, or the server might no longer exist. I saw you use the word "steam" and saw red. :lol: I guess it would be...

    Drm Restricted Commercial Games

    I couldn't accept this, because it has an external dependency. Look at all the problems Valve had with the early days of Half-Life 2 because the Steam servers weren't working properly. Granted, the problems have been mainly solved, but it's not a shadow I'd like to be under. Many, many programs...

    GP2X Does The New 2.0 Firmware Ease Dev At All?

    Not yet. It's on my list, but before that I want to try setting up a different toolchain on the PC side, to try compiling and linking against earlier versions of the libraries so that I can use the shared libraries that are already on the GP2X system.

    GP2X Hardware Dithering ?

    You've got me there. I was hoping you wouldn't ask that until I'd had a chance to look into it a bit more! I initially though it was to do with rendering the YUV data, but the docs suggest that it is applicable to the RGB layer. I have a feeling it might just be poor wording in the docs, and...

    Joystick 45 Degree Rotation ?

    I'm just glad they've sorted these thing out before the "official" release. At least this way, when the new generation of owners and potential owners start to ask questions, we can say that things are now a lot better.

    Acc. Sdl? Silly Question

    Sounds like you have something up your sleeve for the demo competition! ;) Can the blitter render data into the 940's address space, perhaps that might be another option?

    Gp2x Or Ds With Homebrew

    Really?! You've surprised me there. I know anything is possible, but I wouldn't have imagined that the CPUs in the DS were anywhere near fast to enough to render some of the stuff I've seen. I was sure it had rasterising and geometry engines with texture mapping...

    How Fast Do The Emulators Run ?

    Don't forget Jaguar. I'm still waiting to see the emulation of Jaguar T2K for proof of that particular pudding, but it was looking promising until it stalled.

    Power Via Usb

    Probably like the PSP and DS USB/charger cables, where it splits off a power connector which will plug into the GP2X power socket beside the USB.

    GP2X Hardware Dithering ?

    From looking at the docs, it appears that dithering is only applied if the source format has a greater resolution than the destination. If you're in 16-bit colour mode, I doubt if you will see it, as you would have to be rendering from 24-bit sources to have dithering applied, and you might not...
