Mednafen 0.8.4 - 模擬器

- PC-FX: Some RAINBOW registers weren't being reset on emulated
system reset. Fixed.

- PC-FX: Added dummy support for the external bus reset register.

- PC-FX: Altered the way garbage data is handled by RAINBOW to
fix a graphics bug in the Tengai Makyu options screen.

- PC-FX: Reworked a large part of the KING SCSI emulation code,
and parts of the CDROM device emulation code.

Previously non-working-at-all games "Battle Heat" and
"Tengai Makyu" work now.The non-anime game mode in
"Tyoushin Heiki Zeroigar" works now.

"Der Langrisser FX" no longer locks up if you skip the
intro movie."Yuna FX" no longer locks up in one of the
intro movies.These changes will cause some save state
incompatibilities with previous versions of Mednafen.

(Some of the SCSI changes also affect the PCE CDROM
emulation, which may also result in save-state
incompatibility issues, particularly if the save state
occurred during a CDROM data transfer operation.)

- PC-FX: Added setting "pcfx.cdspeed". If you want to change
this, read the documentation first!

Cleaned up the video deinitialization code slightly, and fixed a
few bugs in the OpenGL deinitialization code.

- PC-FX: Reads from the dummy KING register 0x07 will now return
0xFF, per the devkit docs.

- PC-FX: Reads from KING register 0x0B will now return the "DMA
end" bit in D0 set correctly(at least, according to the
developer docs).

Fixed a compilation error after running configure with --disable-nes.

- PC-FX: Reads from I/O port 0xFC0 will *now* return the current
timer counter value. The switch statement mask value was
wrong...

Removed the warning in the documentation about error correction of
raw data track rips, as Mednafen will now perform simple correction
using the EDC and L-EC data(since 0.8.4-rc3).

This could conceivably cause problems with naive hacks/translations/
patches that neglect to update the EDC and L-EC data, so it can be
disabled by setting the setting "cdrom.lec_eval" to 0.

L-EC correction is based off code from dvdisaster.(http://dvdisaster.net/)

- PCE, PC-FX: Removed some debug printf()'s that were left in 0.8.4-rc3
by mistake.
