I got a new power supply for the PC so was able to add a new tutorial: Extended Rotation Backgrounds which demonstrates decoding JPEG images and hardware scrolling and scaling. Also made lots of minor changes to some of the tutorials and verified that they work using DevKitPro release 14:
- Tutorial One slightly modified to display only X and Y coordinate on the touchscreen rather than the direct value from the touchscreen.
- Tutorials two, three, four, five and six modified to use slightly different interrupt handling code as per the interrupt tutorial.
- Tutorial six was modified to use 'padbin' to ensure that the appended GBFS file worked with release 14 of DevKitPro and it now uses the new key handling routines in the newer libnds.
- Tutorials seven and above were also modifed to use the libnds key routines.
