many audio drivers now support device selection - higan: output frequency can now be modified - higan: configuration settings split to individual menu options for faster access to individual pages - ruby: improved WASAPI driver to event-driven model; more compatible in exclusive mode now - libco: fix compilation of sjlj and fiber targets [Screwtape] - ruby: added YV12 and I420 support to X-Video driver - Game Boy: added TAMA emulation (RTC emulation is not working yet) [thanks to endrift for notes] - Game Boy: correct data ordering of MMM01 ROMs (MMM01 ROMs will need to be re-imported into higan) - Game Boy: store MBC2 save RAM as 256-bytes instead of 512-bytes (RAM is 4-bit; not 8-bit with padding) - Game Boy: fixed a bug with RAM serialization in games without a battery - Mega Drive: fix CRAM reads (fixes Sonic Spinball) [hex_usr] - Game Boy: added rumble support to MBC5 games such as Pokemon Pinball - Game Boy: added MBC7 emulation (accelerometer X-axis, EEPROM not working yet) [thanks to endrift for notes] - hiro: macOS compilation fixes and UI improvements [MerryMage, ncbncb] - Game Boy: added MBC6 emulation (no phone link or flash support; timing bugs in game still) - Game Boy: HDMA syncs to other components after each byte transfer now - Game Boy: disabling the LCD completely halts the PPU (fixes onscreen graphical corruption in some games) - Mega Drive: added 6-button Fighting Pad emulation [hex_usr] - 68K: TAS sets d7 when EA mode is a direct register (fixes Asterix graphical corruption) - Game Boy: STAT mode is forced to zero when LCD is disabled (fixes Pokemon Pinball) - LR35902: complete rewrite - icarus: high-DPI is not supported on Windows yet; remove setting for consistency with higan window sizes - hiro: added full support for high-DPI displays on macOS [ncbncb] - ARM7TDMI: complete rewrite - Super Famicom: disabled channels during HDMA initialization appear to set DoTransfer flag - V30MZ: code cleanup - Mega Drive: added optional TMSS emulation; disabled by default [hex_usr] - ARM7TDMI: pipeline decode stage caches CPSR.T [MerryMage] - ARM7TDMI: fixed timing of THUMB stack multiple instruction [Cydrak] - higan: detect when ruby drivers crash; disable drivers on next startup to prevent crash loop - Mega Drive: added automatic region detection (favors NTSC-J > NTSC-U > PAL) [hex_usr] - Mega Drive: support 8-bit SRAM - ARM7TDMI: PC should be incremented by 2 when setting CPSR.T via MSR instruction [MerryMage] - ruby: add Windows ASIO driver support (does not work on some systems due to buggy vendor drivers) - higan: default to safe drivers on a new install; due to instability with some optimal drivers
