Release 7, Preview 3

Release 7 introduces the following new features:

* Mega Drive Plugins v1.0.0. This major update to the plugins system adds
support for external plugins (.dll on Windows, .so on Linux), as well as
support for more than just rendering plugins.
* doc/mdp/ contains the MDP Interface Specifiction Version 1.0.0. This
document is licensed under the GNU Free Documentation License v1.3.
* A new manual for Gens/GS has been created. It is available in doc/manual/.
* The Game Genie functionality has been moved to an MDP plugin. It now
supports 8-bit, 16-bit, and 32-bit patch codes, and uses a new patch code
file format. Old patch code files are supported for loading; however, they
will be written in the new format when saved. Later versions will add support
for patching CPU address spaces other than the main MC68000.
* New MDP Plugin: VDP Layer Options. This lets you adjust the visible layers
on screen, so e.g. you can hide sprites, swap scroll priorities, and lock the
palette to prevent color changes.
* New MDP Plugin: Sonic Gens. This lets you view various information in
memory in several Sonic games. Sonic Gens was originally written by LOst as a
standalone version of Gens.
* New renderers:
o EPX (ported from Gens Rerecording)
o EPX Plus (ported from Gens Rerecording)
o Super 2xSaI (ported from Gens Plus)
o Super Eagle (ported from Gens Plus)
o Blargg′s NTSC filter for MD
* [Win32] Ported the GDI video backend from Gens Plus. It still has a few
bugs, but it mostly works.
* Extended controller configuration format. The new configuration format
allows for up to 128 axes, 256 buttons, and 64 POV hats, whereas the old
configuration format only allowed for 6 axes [5 axes on Win32], 112 buttons,
and 4 POV hats. This mainly affects the Linux version, since Linux usually
reports all axes as axes instead of mapping some axes to POV hats, and some
newer controllers (e.g. the Xbox 360 controller) have more than 6 axes. Older
configurations are automatically updated to use the new controller
configuration format.
* The reverse-engineered 32X firmware, written by DevSter, is now included in
Gens/GS. If you do not have the original Sega 32X firmware files, the
reverse-engineered ones are used instead.
* Added SH2 DMA support for PWM audio. Thanks to Joseph Fenton for submitting
a patch.
* [Win32] Joysticks connected after loading Gens/GS will now be detected in
the Controller Configuration dialog.
* WAV dumping has been reimplemented.
* ROM History now caches the ROM type (MD/MCD/32X), so it doesn′t have to
check the ROM type every time the ROM History menu is rebuilt. This improves
performance significantly if some ROM images were loaded from network shares.
* ROM History now keeps track of compressed files inside of multi-file
archives. For example, if you have a 7z archive containing several different
versions of a game, selecting version 1 will result in a ROM History entry
for that specific version, and selecting version 2 will result in another ROM
History entry.
* Added initial support for the "Palette Select" bit in VDP register 0. If
the "Palette Select" bit is cleared, only the LSBs of each color component in
CRAM is used to determine the colors to display, resulting in a maximum of 8
colors onscreen. This isn′t very useful, but it′s more accurate.
* SRAM can now be disabled in the Options menu. This fixes Puggsy, which
checks for the existance of SRAM and prevents the user from advancing past a
certain point if it exists. (Puggsy uses a password system, not SRAM.)
* Improved PWM scaling algorithm, provided by Chilly Willy on the Sonic Retro
forums.
* A new command line option, "--boot-cd", can be specified to tell Gens/GS to
boot from an actual SegaCD CD-ROM on startup.
* [Unix] Improved VSync support with the OpenGL backend. Both the MESA and
SGI swap control methods are now supported.
* The video subsystem now supports fallbacks. For example, on the Linux
version, if SDL+OpenGL is selected but OpenGL isn′t available, it will
simply revert back to SDL instead of crashing. As an added bonus, this allows
for Gens/GS to start up properly on Windows NT 4.0, since the default backend
on Win32 is DirectDraw 4, but NT4 doesn′t support it. Instead of crashing,
it will fall back to the GDI backend.
* Gens/GS no longer changes non-alphanumeric characters in SegaCD game names
to spaces. This may cause some games to have different names, which will
prevent their BRAM files from being loaded properly. If you have any of these
games, you will need to rename the BRAM files in order to get them to load
correctly.
* [Unix] If a game has a Shift-JIS encoded title in the Japanese title field
and the country code is set to Japan, the title will be converted to the
system′s native locale, e.g. UTF-8. (Win32 support for this feature will be
added once Gens/GS fully supports Windows′ Unicode implementation.)
