SP has issues related to low frequency of syscore.Yes, I figured that bit out. Both implementations have the same issue though. They both use a circular buffer and they both write the whole buffer each time through regardless of the playback position.The code i posted on this thread was referring to csnd:SND (you have to hold L at startup to use it), dsp:
That code is not using a circular buffer. It prepares a buffer full of samples and writes them to the sound driver - which puts them in a queue to play next. A circular buffer requires writing the samples to the correct location in the buffer to stay ahead of the playback position without writing past it. The ndsp driver can work this way submitting new buffers instead of looping the same buffer. There would need to be some timing added to prevent the buffers from being generated to quickly - so that the are produced at the same rate they are consumed.
How are you using the textures? It's hard to tell you without looking at some source.
I basing it off of the gpu textured cube demo.
I'm not familiar with Xem's tools but from the description it reverses the byte order. Try using gimp and exporting as a .data raw file, then just rename that to .bin, I know that works
Most of the documentation we have on the gpu is on 3dbrew. It doesn't explain much about the tiling itself, but textures and the framebuffer are tiled. The framebuffer gets converted during the display transfer. The display transfer function can either tile or untile depending on what arguments you pass.
Install devkitPro w/ devkitARM[edit]
DevkitPro is an essential set of toolchains for homebrew development.
Linux / Mac OSX[edit]
1) Download the devkitPro perl script
2) Download the latest ctrulib from GitHub. Place the ctrulib folder in the same location as the perl script
3) Open a terminal and execute these commands:
cd /path/to/the/script
chmod +x devkitARMupdate.pl
sudo ./devkitARMupdate.pl /opt/devkitPro
echo "export DEVKITPRO=/opt/devkitPro" >> ~/.bashrc
echo "export DEVKITARM=\$DEVKITPRO/devkitARM" >> ~/.bashrc
echo "export PATH=\$PATH:\$DEVKITARM/bin" >> ~/.bashrc
source ~/.bashrc
cd ctrulib/libctru
