Unfortunately emulators will quite often run code quite happily that will then die on hardware. It's difficult to say what the problem might be without seeing your code but STL streams are quite memory heavy - see http://www.coranac.com/2009/02/some-interesting-numbers-on-nds-code-size/ for some ...

Hi,

I'm using SDL to perform fadein/fadeout on my game.

On the PC in 24 bit mode I use alpha channel to perform this, but on the DS I have opened a 8 bit screen to save memory and CPU (maybe I'm misled because 16 bit depth would be better but I have tried this first and it was rather slow).

So my ...

Hi,

I just want to report this (on devkitpro 1.5):

I was using isstrstream to parse integers, floats instead of atoi/atof. Worked OK with NitroFS on emus, but on the real DS with libFAT it locks up.
I don't see why it locks up since even if it's a stream, it's a stream on a buffer, not on a file ...

Hi,

Following the advice of Steven, I changed some voidfn stuff in homebrewmenu source and could recompile it. But now when I'm trying it on my M3.

I select fat:/NDS/mygame.nds. Any game gives me:

0 argument(s)
Init'ing FAT...

=> lockup!

I have tried a lot of homebrew games (including mine) and ...

Hi,

Since .elf contents are loaded in memory on Nintendo DS and that we face big memory limitations (specially when including graphics & sound in the .elf file), I propose a modification of the Makefile template (if there's one) or at least suggest some fine option which allow to reduce code size ...

StevenH wrote:No IIRC the homebrew menu code was updated to the next release of the toolchain, change it from the VoidFN to VoidFunctionPointer - it should now compile.

It does, indeed! thanks a lot. Will try that.

What was the error?

What did you change?

Err, sorry I just checked, it was an old app (diggers) that I had downloaded that defined "near" with a #define => broke the compilation but not your fault. Diggers is broken, not videoGL! Sorry, I'm learning slowly here :)

devkitpro rulez!!

bye

Hi,

I have tried to compile some applications including videoGL and I had a strange compilation error. I later understood that the "far" and "near" variable names were potentially a problem in the .h file.

After renaming them, everything compiled OK. I thought I should report it if nto already ...

Hi,

I have downloaded source code for HomebrewMenu, and I just type "make" in the devkitpro MSYS console. It does not go very far.

arm-eabi-gcc -MMD -MP -MF /home/JOTD/HomebrewMenu/bootloader/build/boot.d -Wall -Os -mcpu=arm7tdmi -mtune=arm7tdmi -fomit-frame-pointer -ffast-math -mthumb -mthumb ...

Glad you got it working in the end. It might be worth sending a patch to the SDL maintainers if you have the time.

The problem with SDL NDS port is deeper than that. I had to switch to maxmod because SDL sound was not working on NDS. It even froze the system (IRQ?) at some point.

I tried to ...
