baccf336d7 Complete rewrite of the APU. Channel 3 is complete and passes all the relevant tests from blargg’s suite, as well as PCM34-based tests. Actual sound output is basic and limited, though. 2017-07-21 19:06:55 +03:00

00623d4eea - Added audio supersampling support to greatly improve audio quality.
- Fixed a bug where low sampling rate or disabled sound resulted in wrong APU behavior.
- Added API to get the current number of pending samples.

Closes #8.

a925ef130d Stabilizing API: New joypad, debugger and reset APIs; internal APIs and direct struct access are no longer available without defining GB_INTERNAL. The SDL port uses the new “public” APIs, as well as most of the non-debug Cocoa code. 2017-04-17 20:16:17 +03:00
