will this work with r24
will this work with r24? - Echo
Not tried it with > r23 of devkitarm. You may need to compile the arm9 side with -Os option to shrink code as much as possible.
Have you tried it with r24? -Eris
notes on helix updates
- if remove lrlr interleave can write directly to the pcm output buffer, but at end of song can a frame be less than 1152 samples??
- maybe add round robin support to helix directly?? (would need to pass cpos and bsize to helix somehow)
- find registers to use by placing dummy code? (best to find proper c/arm register usage and calling convention docs)
- on current deinterleave function might be more efficient to calculate if/where it overflows first and use 2 loops if necessary (would save from the 'if pos >' code each frame)
