Sega Li v1.4 alpha

Iron, 06:53, 19-11-2005

Обновился один из многих развивающихся эмуляторов NES/Famicom. Исправлены ошибки, добавлена поддержка новых мапперов.

mappers: fixed bank overflow in mapper 234
switched rendering to DirectDraw, with support for 16 or 32 bit pixels, optional clipping, optional vsync, window stretching
PPU: odd frame cycle deduction only happens when rendering is disabled
mappers: MMC3 and MMC6 now share the same irq handler, this fixed My Life My Love - Boku no Yume - Watashi no Negai
improved the DirectSound module, to allow realtime buffer updating
APU: added emulation of the square wave channels, triangle channel, noise channel, and output of the DMC... sound output isn't yet how I want it to be though
mappers: added MMC5 sound: 2 square wave channels like in the NES APU, and a PCM channel
PPU: fixed timing of status register clearing, and vblank NMI
source: added a simple macro for memory allocation and cleaning
mappers: added iNES mappers 89, 67, and 69 (Sunsoft 5/FME-7, including the AY-3-8910 soundchip that's used in Gimmick)
APU: reading the status register doesn't clear the DMC irq
PPU: support for vblank flag/NMI suppression
PPU: removed warming-up behaviour where some register writes would be ignored (needs more testing)
mappers source: better mirroring handling, more compact bankswitching macros, each group has their own struct instead of one big mapper struct, other miscellaneous cleanups
mappers: added iNES mappers 47, 76, 77, 86, 180, 184, 257, 289, 301, 304, 486, 700.. ok ok, I lied, they only go up to 255
