    GP32 I Guess I Found The Cause Of The Gp32 Sound Bug

    I've always thought there should be a sticky on this... Most people don't go looking through the technical specs very often, and on a few occasions people asking why their sound is crackly get a rather snotty reply about it being covered before and a link to that 300 page document.

    GP32 Gta Clone

    It may be obvious, but it is quite hard to program well... Devloping a model from the maths is quite difficult. I have never tried doing reasonably realistic car physics myself, so it may be possible to get passable results by a trial and error, building up the model type fashion. Going...

    GP32 Let's Flog A Dead Horse!

    May not be too bad... you should be able to "guess" jumps to WRAM in the same way as writes to video memory, then work backwards to work out the code that needs converting. OK... that may be too bad. And doesn't solve the problem of, say, some code being held compressed on the rom before being...

    GP32 Help! Making My Program

    For reference: To compare strings, you need to use a function: strcmp(a, "div"), will equal 0 if they are equal, a positive if "a" is after div alphabetically or negative if "a" is before div alphabetically. You will need #include <string.h> at the top of your code to use strcmp as well...

    GP32 Let's Flog A Dead Horse!

    It is fairly easy to get a stack trace in C... it has a well formed stack. (Never mind the fact that the ARM chip, in common with most CPU's, has instructions defined almost exclusively for calling functions & building the stack, so even if they are using lots of assembler, you'll still probably...

    GP32 Let's Flog A Dead Horse!

    Theoretically, you can't do this; you come up against the halting problem. However, it can be done with a large proportion of programs if a skilled user works with it. My house mate works on Specialisation, which is fairly closely related to this sort of thing. In both cases you have to derive...

    Favorite Atari 800 Games

    Atari 800XL was my first computer, although I was a little young to appreciate it. I like Blue Max. It's not really agreat game, like most of the others mentioned here, but it is quite fun. For awhile.

    Help Me Fix My Abduction Game

    Could you post a couple of links to the threads with the problems you are having? I haven't been on the boards for a while, but would like to help if I can (i always lose interest before I finish any of my own games, but feel I should contribute something).

    Power Socket Help

    Have you tried switching the polarity round? Yes? Well, I don't have any ideas then.

    GP32 Array Definition

    Yes, you shouldn't need to do -1000. Even if you did, it would be 2000 since ints are 4 bytes on a Gp32

    GP32 24bit Bmp Work On The Gp32??

    There is BMP loader code some where on these forums. Sorry, can't remember who made them and can't be bothered to search for the code now. Supports 8bit and 16bit..

    Gba Emu

    Sigh... Nintendo aren't saying that emulation is illegal... quite the opposite in fact. They are claiming they have come up with the "innovation" of emulating a GB/GBC/GBA on a low power device (a PDA type device being listed of one of the examples). They have patented this innovation, and...

    GP32 Colors Colors Colors

    I was going to say that the writeback buffer would join two 8bit writes into one 16bit write... but the writeback is disabled on the framebuffers. However, a 32bit write is definately slower than an 8 or 16 bit write. While the ARM is 32bit, the data bus is only 16 bits wide, so it takes TWO...

    GP32 Double-buffer Help

    I suspect this may be down to that pesky Samsung Writeback bug, which has been discussed many times on this board. It's most common symptom is crackly sound, but it can cause LCD flickering too. Are you usign the SDK rectFill functions a lot ? They cause this bug to manifest.

    GP32 Centering X & Y Axis To Sprite

    In actual code, should avoid /2 or dividing by any power of two. Divide is done through a SWI and takes around 100 cycles. The ARM chip has a barrel shifter, so if you use >> 1, (Left shift by 1), it takes NO extra instructions. X_sprite=(X_size_screen-X_size_sprite)>>1...

    Atari 800 & Henrys House

    What bugs me is Orc Attack don't work quite right... it looks fines for a bit then you realise that the orcs don's seem tobe able to build their ladders up, which means they have a lot of difficulty reaching the top... This problem occurs in all the emulators I tried a while a go, so it must be...

    Free Gpcinema After April?

    Fairly sure you can only redownload during a certain period (like two weeks after first downloaded), Will check at home when not on a messed up browser.

    Advance War 32 Beta 1

    I would just like to re-iterate the point: from an intellectual property viewpoint, whether you charge for what you produce makes absolutely no difference. As a simple comparison, if you steal someones gameboy, then give it a way for free, you are still guilty of theft. (Note that copyright...

    Sports Game

    Speedball 2 on Castaway i great fun... Not exactly a straight sport game... but great fun. I've been playing a bit of Final Match Tennis on GPengine, but find it absurdly difficult.

    Free Gpcinema After April?

    This is handy... I've already bought it, but lost the .fpz in a harddrive failure. Now I'll be able to buy more SMCs and put movies on them... so more than 1 movie a trip,.
