Mednafen 0.8.4-rc3 - 模擬器

21 Oct 2007

Changes:

PCE: Added preliminary(it works, but the code needs to be cleaned)
ADPCM support for HES rips.
PCE: Interrupts will be enabled with a CLI after a HES' init routine
is called, to fix rips that neglect to do it themselves.
PCE: Added support for HES rips that try to write data where it really
shouldn't be written(some CD-ROM game rips do this), though a
warning will be printed the first time this occurs after loading.
PCE: Added sanity checks to the HES loader to prevent crashes if
invalid data is present.
PCE: Reads from the I/O port will now return D7 as clear when emulating
a PCE CD game.
PCE: ADPCM RAM is now reset(to 0) on emulated PCE reset.
PCE: Sprites trying to pull tile data from $8000-FFFF of VRAM will now
be invisible(probably not correct, but trying to emulate
indeterminate effects is too difficult :b). Fixes a minor sprite
garbage issue in Camp California.
PCE/PC-FX: Fixed VRAM DMA source/dest increment/decrement bits(the source
and dest were flipped). Fixes a problem with Fushigi no Yume
no Alice.

Moved some code in the source root directory to appropriate
subdirectories.

Added setting <system>.debugger.disfontsize, valid settings being
"xsmall", "small"(default), "medium", and "large", to control the
font size used to draw the disassembly text. Note that there may
be overlap with other parts of the debugger at font sizes larger
than the default.

Refactored a few address space and register group debugger support
functions out of individual system code.

Fixed various low-impact memory leaks.

The version of Mednafen last run is now stored in the configuration
file as a comment(this will be necessary for changes in 0.8.5 or
later that will involve proper escaping/unescaping and quoting of
strings, to prevent problems with extra whitespace added by manually
editing the configuration file).

Fixed state rewinding on big-endian machines, and removed some
unnecessary operations from the state rewinding code path.

Mednafen will now refuse to try to load ROM images larger than 64MiB,
as a sanity check.

mmap() and madvise() will now be used to load ROM images, assuming
they're available(UN*X only, generally).

Errors during automatic IPS patching are now fatal.

Sped up loading gzip'ed ROM images.

Removed a global variable from the NES emulation code that had invaded
state.cpp. Though, this makes the error message when trying to use
save states with authentic Game Genie emulation very unhelpful...

GBA: Added support for loading a real GBA BIOS ROM image, using the
setting "gba.bios".

GBA: Added the ability to specify the backup memory type for games by
creating a file with the same name as the ROM image, with the
extension replaced with "type", in the "sav" directory under the
Mednafen base directory.
Example: SexyPlumbers.gba -> SexyPlumbers.type

One or more of the following strings(on separate lines) may appear
in the file:
sram
flash
eeprom
sensor

Additionally, the flash size can be specified by specifying the
size(real size, or divided by 1024) after the type, like "flash
128" or"flash 131072".

PCE: Improved noise LFSR and volume emulation, thanks to cgfm2 for the
detailed information.

少數能支援PC-FX模擬的Multi System emulator，PC-E/CD的模擬效果也很不錯。
