Major toaplan2.c updates [Alex Jackson]
- Some sets reparented and renamed as well as a cleanup of source comments: grindstm (parent), vfive (clone) kingdmgp (parent), shippumd (clone) The set formerly known as "sstrikera" is now "sstriker" and is now the parent of mahoudai (clone). Reverted batrid to batrider and bkraid to bbakraid. - Put common init code into MACHINE_START, leaving DRIVER_INITs only for games that actually need unique initialization. - Dead code cleanup: Removed old hacks and some no-longer-used used member variables from the driver class. - ROM banking cleanup: Added a device address map for the OKI in fixeightbl. Stopped misusing the bank system for memory that isn't actually bankswitched (fixeightbl again) Simplified the Z80 ROM banking (and loading) in the Raizing games. - Address map cleanup: Unified 8-bit shared RAM handling between the Z80-based and the V25-based games. Replaced lots of pointless READ_HANDLERs with AM_RAM_WRITE. Moved fixeight EEPROM handling into the input ports instead of using READ/WRITE_HANDLERs. Incidentally, this makes toaplan2.c the very first MAME driver to use the AM_READWRITE_PORT macro. - Removed IPT_VBLANK input ports (no longer used since the video rewrite) - Removed Truxton 2 player 2 "button 4" (after confirming that the game never reads it) and changed player 1 "button 4" to an IPT_OTHER not bound to any key by default, since it's clearly some kind of test/debug input not meant to be hooked up in a regular cabinet (for one thing, it works whether you're actually playing or in attract mode) - Added button 3 to Batsugun Special Version. It's a full auto fire button like Cave games have. The service mode input test doesn't show it, presumably because Toaplan didn't bother to update the service mode code from the original version of the game. - Fixed region jumpers and dipswitches in many sets, based on analysis of the program code and strings in the ROMs. - Added a #define to optionally make Truxton 2 stereo (commented out by default). See the comments at the top of the driver and in the MACHINE_CONFIG. - Corrected kbash ROM names, thanks to information from Charles MacDonald. Also fixed inconsistent ROM naming between some of the batrider clones. - Loaded bbakraid default EEPROM as a ROM rather than hardcoding the contents into the driver. - Completely removed audio/toaplan2.c, which isn't needed any more now that all the V25s are decrypted and hooked up.

|

The Toaplan 2 hardware with V25 secondary CPU controls the sound through
|
||||
to a YM2151 and OKI M6295 on some boards. Here we just interpret some of
|
||||
commands sent to the V25, directly onto the OKI M6295
|
||||
|
||||
These tables convert commands sent from the main CPU, into sample numbers
|
||||
played back by the sound processor.
|
||||
The ADPCM ROMs contain intrument samples which are sequenced by the
|
||||
sound processor to create some of the backing tracks. This is beyond the
|
||||
scope of this playback file. Time would be better spent elsewhere.
