Lior Halphon 544ca2be4c Changing the timings of memory writes so they’re not effectively one T-cycle late. This screws up APU’s cycle accuracy for now. 2018-03-05 21:17:37 +02:00
Lior Halphon ef670986c6 Rewrote PPU (currently only emulates DMG correctly) to use the new timing mechanism. Removed “future interrupts” (No longer required because SameBoy is now T-cycle based) 2018-02-25 00:48:45 +02:00
Lior Halphon 42ab746a66 Starting to remove the delayed interrupts hack – done for timer interrupt, broken for display interrupts 2018-02-23 15:33:44 +02:00

Lior Halphon 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
Lior Halphon c4ccbd5cce Improved serial interrupt timing, fixes boot_sclk_align. 2017-06-23 17:58:04 +03:00
Lior Halphon 65b0dcb2c5 Fixed a bug where SameBoy freeze for a moment after leaving turbo mode 2017-06-03 17:02:12 +03:00
Lior Halphon 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.
- This change broke save state compatibility with v0.8 and older
Closes #8.

Lior Halphon c766704267 More accurate FPS capping that tracks time correctly even when the screen is off. Should also support restarting the LCD during blank to increase FPS to 63. 2017-04-21 16:00:53 +03:00
