Dsi memory pit - memory corruption

Nds files launched from memory pit with sound enabled. Memory pit seems to leave sound capture enabled which causes heap corruption. Adding the following to the arm7 initialization seems to fix the issue:
REG_SNDCAP0CNT=0;
REG_SNDCAP1CNT=0;

Re: Drawing a citro2d scene with 2 shaders?

I think I may have experienced a similar issue. I was trying to add a geo shader for a particle system. The geo shader was only used in frames where particles were visible. It would work for a little while but the gpu would hang after particles were rendered. I assumed I was doing something wrong - ...

Re: OpenGL glTexImage2D with raw bitmap data

raw bitmap data is not the same as a bitmap file (.bmp file). a .bmp file contains header information about the image data and the format. raw bitmap data does not include a header - and is literally just raw data. It is unclear which format you are using - you say raw bitmap data, but referenced co...

gpu shader - system hang

I am trying to implement a particle gpu shader. It seems to be mostly working correctly - except that it will occasionally deadlock the system and I cannot figure out the issue. It only happens on hardware - citra does not see any issues as far as I can tell. Any assistance or ideas would be appreci...

Re: Make (to create build) error

Not sure how familiar you are with msys2 - on windows there is a start menu entry to launch a msys2 shell under devkitpro. This should be use instead of a windows command prompt for command line tools. Keep in mind that paths are a little different. For instance the c: drive is mounted as /c/ instea...

Re: Can't scan X_KEY since update

do you have custom arm7 code? it sounds like something may be interfering with getting the button state from x and y from arm7. the latest updates for dsi mode compatibility may be need some adjustments in your code.

Re: Https request

Hi everyone! I was wondering if it is possible to make https requests from a nintendo DS, as I understand there's no support for it and the encryption seems complex enough to have an external library that implements it. I was thinking, would it be possible to use something like openssl? Thanks in a...

Re: Old Homebrew Project (NDS)

Palib is shunned for a reason. It requires old versions of devkitpro toolchains and libraries and the tend to mess with the libraries and break stuff. So you would need to ditch palib and replace that functionality using current toolchains and libraries. It sounds like a considerable amount of work....
