What's new
|
|
==========
|
|
|
|
0.5: patched sound for real stereo (using NK's solution); better init code.
|
|
|
|
0.4: lots of cleanups; sound is threaded now, double buffered too; 8 bpp video support; better exiting code.
|
|
|
|
0.3: shorter library; improved joystick diagonal detection.
|
|
|
|
0.2: better code layout; public release.
|
|
|
|
0.1: beta release
