Replace the SDL-derived controller support with my own JoyKit framework. Adds rumble support, LED support, better manual and automatic configurations, analog speed controls.

Increase input polling frequency in the Cocoa and SDL frontends, should make inputs look less synthetic and potentially reduce input lag

APU glitch: When turning the APU on while DIV's bit 4 (or 5 in double speed mode), the first DIV/APU event is skipped.

Fix CGB timings
2018-03-23 12:58:51 +03:00
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
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
42ab746a66
Starting to remove the delayed interrupts hack – done for timer interrupt, broken for display interrupts

Components not affected by CGB’s double speed mode now operate in 8MHz mode to theoretically make advance_cycles(gb, 1) safe.
2018-02-20 21:17:12 +02:00

Added CPU under/over-clocking support in Core, add under-clocking hotkey in the Cocoa port, allow modifier keys to be configured as input keys in Cocoa.

2MHz audio downscaling support. Implemented NR50 and NR51.

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.

- 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 .

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.

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.
