As posted on http://devkitpro.org/viewtopic.php?f=13&t=2222

Note: The current desmume stable release doesn't work with the new FIFO code. It has been fixed in SVN and will be working again with the next release.


libnds 1.4.6, the default arm7 0.5.16 and dswifi 0.3.13 are now available through the windows installer as usual and from the getting started page on the wiki.

libnds 1.4.6

  • Improved FIFO communication code.
  • add getBatteryLevel for power staus.
  • add glFog functions.
  • improve PCX decoder.
  • corrected affine matrix order.
  • Fixed fifoSendDatamsg to allow 0-byte messages.
  • allow for exceptions from usermode.
  • touchscreen working in DSi mode.
  • improved linked list code.
  • documentation fixes and code cleanup.


default arm7 0.5.16

  • recompiled with latest libnds.


dswifi 0.3.13

  • defer socket close while data is sending.


With thanks to Apples, Vuurrobin, Zeromus and Dovoto for their contributions to these releases.

Nice work!

Quick question, what was wrong with the affine matrix order? Just seeing if I'll have to update some functions.

Was there a bug? I had a problem with it and would be nice to know it's gone...

Looking at some diffs it seems that related to the libnds sprite functions. Shouldn't have any effect if you were using direct register access.

meh, fixed. That's what I get for copying text from old posts & modifying.

Nothing specific, just refactored some code that might be unstable in particular situations. Hard to know if your problem is gone without knowing what it was.

It was fifoSendValue32() failing after the 127th use. We were discussing it here -> http://devkitpro.org/viewtopic.php?f=15&t=1510

the hdy and vdx registers were wrong in the struct (vdx should come before hdy). the sprite rotatescale function then compensated for the bug, so I corrected them both. the rotatescale function works the same as before and the affinematrix function/direct register access now behaves as it should (remember that it's an inverse affine matrix).
