I looked more closely at the BIOS interrupt handler and noticed that to load 0x03007FFC that it actually used 0x04000000 - 4 I guess doing it that way...
How do you write to the flash cart from the GBA? I have tried to write my flash cart with the MBV2 cable. Just incase it was just my flash cart, I tried a...
Hi people im new to the group and was wondering what you use for converting sound to C/C++ files i've heard that the program called 'Simon' works quite well...
Can anyone tell me where I can buy a flash cart for the gba? I can't find them at lik-sang and game gizmo aren't trading anymore. Alternatively is there a way...
Hello chaps, I've a pretty large project which I'd like to selectivly optimise ( if possible ) using ARM ADS 1.2. One of the more complicated files gets used a...
Hi everyone! I'm in my early steps in GBA development, and I've chosen to learn the environment by writing a simple vector gfx engine for mode 4. I'm almost...
Okay, I am trying to understand flash programming on the gba. Looking at an intel data sheet it basically says write 0x90 to any address then read from an...
I was able to get a Dhrystone score of 3674 for ARM code running completely out of IWRAM (except for __divsi3). Of course, this is not great news as it might...
hi, last week my gameboys were stolen on a train and now I need a quick way to get a gba tv out adaptor but the guys over at cdworld.co.uk don't seem to sell...
hello world, i was wondering if someone else have also experienced the following problems with the tuner. i got it today, and after almost 1h usage it seems to...
I was compiling the Queens problem on David's benchmark page. I had everything except a few functions in iwram, and decided that maybe I could speed it up if...
Hi, I'm working on a (fairly large) engine project, just wondering if my methods of memory management are efficient (note: I'm using HAM). At the moment's...
Do PogoPlugins and Multiboot copy from ROM ever work together? If so then there is a contradiction in saying that I can support appended assets and ...
Running the Dhrystone benchmark out of iwram yields a score of: 3674 Running as a multiboot (so everything not in iwram is in ROM): 3541 Turning off multiboot,...
... I have another possible improvement regarding interrupt handling. The handler in Jeff Frohwein's crt0.s uses a big "switch statement" like this: and...
Now that I have actually read about PogoShell, I have a question. It would seem that PogoShell plugins are just regular images which happen to read a specific...
Thanks everyone who provided feedback. I've come up with a solution which I believe addresses all the issues and fits within the limited scope of what I...
The talk about appended assets vs the heap prompts me to ask a question to any GBA coder out there : does anybody actually use the heap in a finished game ? ...
... Well... It's possible I was making an invalid assumption, but... As I recall, HAM is distributed with Krawall as part of the package, and Krawall is very...
I think there are two issues with this, only one of which is solved by the _sbrk() call. The other is Multiboot images on ROM (.mb.gba) where the ROM is...
What value is placed at 0x03007FFC by default? Is it zero? If the IRQ vector is zero, does the bios still attempt to call it? -- The Phoenix - NekoCo - The...
... First of all (and this is not intended to cause offense to anyone), I have no sympathy for anyone who wants to subvert the GPL. I support Free Software...
Forget everything I said about __fixup_heap. The very same logic can go into the _sbrk, without adding to the already very busy crt0.o The justification for...
