Fixes/resolves:

New Games / Clones supported or promoted from GAME_NOT_WORKING status

• Dacholer [Pierpaolo Prazzoli]
• Kick Boy [Pierpaolo Prazzoli]

both are missing proms (causes bad colours) and lack sound

clones

• Clash Road (Status License) [Steve Rice, Pierpaolo Prazzoli]
• Golden Axe RODA (Japan) [Tormod Tjaberg]
• Thunder Cross (World?) [Andreas Thorsén]
• PushMan (Korea) [Andreas Thorsén]

New games marked as GAME_NOT_WORKING

• Tarzan (IGS)

no work been done on it, might be gambling

• Magical Tetris Challenge
• Eleven Beat

these are n64 based, skeleton driver only with board layouts, maybe more useful to n64 emulator authors.

• See See Find Out [Tomasz Slanina]

mostly ok, but sometimes pauses

Version 0.91u1

Released: 2005-01-30

This has been released quickly after 0.91 due to a bug left in the Memory System. I consider core bugs critical and prefer to see them fixed in official updates as soon as possible.

--

• Compiler Warning fixes for non-GCC compiles [Bryan McPhail]

cpuintrf.h

• Duplicate enum

cpu/mh68hc11/hc11ops.c

• C99 variable fix & warning fix

sound/streams.c

• C99 variable fix

vidhrdw/pacman.c

• C99 variable fix

vidhrdw/model3.c

• C99 variable fix, unused variable fix
• macro redefinition fix

vidhrdw/namcona1.c

• Fixed unused variable warning

vidhrdw/taitoic.c

• Fixed unused variable warning

vidhrdw/wgp.c

• Fixed unused variable warning

windows/debugwin.c

• Missing #include

• More compiler fixes [Lawrence Gold]

src/cpu/arm7/arm7core.h

src/cpu/powerpc/ppc.h

• Trailing comma at the end of an enum.

src/cpu/mc68hc11/hc11ops.c

src/cpu/mc68hc11/mc68hc11.c

• ANSI C89 unfortunately doesn't allow unnamed structs or unions, so I had to uglify this code a bit. A cleaner solution is welcome.

src/drivers/segaorun.c

• Returning a value from a void function

• Even more compiler fixes [Lawrence Gold]

• Fixed SFTM on 64-bit builds/systems [R.Belmont]

• Changes to Lethal Enforces [R.Belmont]

• Implemented 48xx bankswitch region, which can toggle between custom chip registers and RAM (evil!).
• Removed hack to pass POST since we now do it the right way
• Corrected 56832 RAM interface, added preliminary support for external linescroll RAM on the 56832. This helps with the garbage tilemaps a bit since linescroll data is no longer getting sprayed all over VRAM.

(note, with this update the driver was just crashing when I tested it, so maybe something is wrong)

• NEC disassembler update [Bryan McPhail]

• Added support for encrypted opcodes in i386 disassembler (for Irem games).
• Added some of the NEC V series instructions into i386 disassembler

• external volume control and stereo support [Derrick Renaud]

• Fixed garbage around life-bars in rabiolep (rabiolep37b1gre) [David Haywood]

• Fixed? blanking out of levels at certain scores in Solomons Key (solomon36b10yel)

This appears to be some basic protection, needs further investigation [David Haywood]

Main purpose of this update is to clean up the compile warnings

--

• Warning Cleanups [Nathan Woods, David Haywood]

• Added a kludge for Astra Super Stars to let it run past a nasty code, nasty because I highly suspect it's a sh-2 bug,will be worked out in the future.
• Added some new vdp2 registers,for example the DISP one for avoid transitions draws.
• Re-added the layer disable/enable code that I sent in the past which was lost,and removed the possibility to disable layers with non-debug builds
• Started to add default eeproms for the various games,for now I've hooked up the one in Shienryu to let it run already with Vertical Switch.
• Added the dynamic clocks,hopefully now 100% working.

• TNZS driver update [Nicola Salmoria]

• fixed crash due to code execution across bank cboundary (tnzs36b16yel)
• removed kludges which were required to run Arkanoid 2 (they were just mirror addresses)
• added sprite banking (same as seta.c). Insecotr X and other were obvoisly running at 30fps before, now they are ok. Also fixes insectx13b16gre and insectx236b16gre.
