0.235GIT

- New games: Paris Dakar (31/03/87, Spanish)
- New Non-Working games: Dracula's Castle (Magnet System)
- New clones: Rafflesia (not encrypted), Rescate Lunar (Spanish bootleg of Lunar Rescue) and 'S.V.G. - Spectral vs Generation / Sheng Mo Shiji (M68k label V101HK) (ARM label V101HK, ROM 06/20/05 S.V.G V100)'
- New devices: f2mc16, mb90610a, mb90611a and mb90641a
- CPU
  . Fujitsu Micro F2MC-16: Emulated various additional instructions and modes. Fixed banking for direct addressing mode. Fixed semantics of CLRB and number of bytes consumed by SETB. Fixed mistake with calculating N and Z flags for SUB and CMP and writing incorrect result for SUB. Use INC(W)(L) A and DEC(W)(L) A pseudo-operations in disassembly. General cleanup: Added helper functions for increment and decrement operations and short direct banking. Rationalize use of temporary variables. Modify only lowest 8 bits of accumulator for XOR A, #imm8. Perform a 16-bit rather than 8-bit write for MOVW @RLx + #disp8, A. Use SSB instead of USB for @RW3 or @RW7 addressing when S flag is set. Fixed numerous flag calculations. Emulated many more opcodes. Added interrupt callback for debugger. Correct disassembly of MOVW io, A. Added "extra" I/O CPU (MB90611A F2MC-16) to Motocross Go! configuration
  . Texas Instruments TMS57002 'DASP': Genearate seaparate DASM header
- DEVICE
  . 3dfx Voodoo Graphics: Address minor coverity complaints
  . CHDMAN: Added a few more hard disk templates (Seagate, Maxtor, Micropolis...)
  . Floppy
    . Fixed segmentation fault saving FM track. Incorrect cell size for FM track results in empty bitstream that ultimately causes data.empty() to seg fault (formats\imd_dsk.cpp).
    . Don't assume string iterators can be indexed (reported by Coverity software) (formats\fsmgr.cpp)
  . SMC91C9x Ethernet Controller: m_loopback_result needs to be a signed into so negative status codes remain negative. FDSE bit was masked out. When full duplex switched internet is active, deferrals and collisions not used. Implemented AUTO_RELEASE.
  . TC0780FPA Polygon Renderer: Fixed texture issues in Operation Tiger (video\tc0780fpa.cpp)
- aleck64.cpp: Fixed handling of 8bpp framebuffer mode. Adjusted how VI scan-out functions. Swapped 'magic matrix' dither pattern axes to match hardware tests (machine\n64.cpp and video\n64.cpp).
- albazc.cpp, albazg.cpp and chanbara.cpp: Made use of object finders and other minor cleanups
- megasys1.cpp
  . Documented different clone 'P-47 - The Freedom Fighter (Japan)' ROM board configurations
  . Correction to the audio CPU memory map and verified that clone 'E.D.F. : Earth Defense Force (bootleg)' has an undumped PIC. Verified XTAL and clock.
  . Dumped Peek A Boo Japan 1.1, matches peekaboo set.
  . Standardized PROM locations for games running on 1A board.
- mermaid.cpp
  . Added missing items to state saving
  . Updated to use measured clock and marked Mermaid and clone as imperfect graphics. Note: Incomplete GFX emulation in Mermaid (see MT07985 and MT08000).
- namcofl.cpp: Fixed network status error, this also fixes the paralyzed flagman in Final Lap R (ID 08042).
- ssfindo.cpp: Preliminary QS1000 hook up. There seems to be a bug in the ARM_VIDC20 device that causes static/bad sounds. Just set the related volume sliders to 0 to hear the QS1000.
- timelimt.cpp: Halve maincpu NMI rate and fixed spriteram out of bounds access (ID 08046). Note: PCB output video confirms that the enemies in Progress move too fast in MAME (https://youtu.be/3MX_qCf_no0).
- 4nin-uchi Mahjong Jantotsu: Updated to use finders and other small cleanups
- AGEMAME: Added missing sound roms for 'James Bond (Maygay) (M1A/B) (set 1)'
- Motocross Go!: Added "extra" I/O CPU (MB90611A F2MC-16) to configuration
- Operation Tiger: Fixed lockup issues and improved tilemap emulation in TaitoPJC driver. Fixed texture issues in Operation Tiger (video\tc0780fpa.cpp).
- Royal King Jang Oh 2: Added banking. Almost playable, but bad colors.
- Description changes of Peek-a-Boo! (Japan, ver. 1.1)
- MAME
  . VIDEO RENDERING SYSTEM
    . Fixed automatic sizing of snapshots/recordings (emu\render.cpp). This fixes bad scaling on snapshots and recording when using -uesx and forced scale factors.
  . INPUT: Slightly cleaned up OSD input modules. Removed support for DirectInput 7 and earlier. It hasn't been tested in years, and it's not relevant on any supported OS. DirectInput is effectively finalised at version 8 and is unlikely to get an API update in the future. Use more string[_view] and fewer C strings and tightened up scope of a few things.
- Compiling
  . Fixed OSD=mac compile (osd\mac\window.cpp and osd\modules\render\drawogl.cpp)
- Debugger: Allow the bpset/wpset/rpset & map commands to act on any cpu, by prefixing the index or name with a # and passing as the first parameter (debug\debugcmd.cpp).

In our lab, theory and practice are combined: Nothing works and no one knows why."
