Landing Gear
Taito, 1995

This is a flight simulator game running on Taito JC System hardware.
The system comprises two boards plugged together back-to-back via five high density connectors.
The top board contains the main CPU, all RAMs, graphics and sound hardware and the bottom
board contains the game ROMs, communication devices and a MC68HC11 MCU. Landing Gear
is a single player game so the board does not contain any communication hardware.
This hardware seems to be the earliest revision of the JC board. This is the only JC game that
had a 28-way edge connector, which is actually almost JAMMA. The power/GND, video and
most buttons (test/service/coin/start etc) work fine using any standard JAMMA cab. However the
analog controls are wired to another connector on the bottom PCB via an interface board.
When other JC bottom boards are swapped to this top board, they will run fine, but some of the
graphics are messed up. This is probably due to the different PALs and their changed locations.
This seems to mostly affect the texture mapping (tested with swapping Side By Side 2) as the title
and most of the background graphics are ok but the car textures are just a mess of pixels.

      All 3K files are PALs type PALCE 16V8 and saved in Jedec format.
      6264: 8K x8 SRAM
      SMC_COM20020I: Network communmication IC
      MC68HC11: Microcontroller with 64k internal ROM capability (not read but probably protected anyway ;-)
      ROMs .36-.39 are 27C4001, main program.
      ROMs .5-.12, .18-.25 are 16M MASK, graphics.
      ROMs .32-.35 are 16M MASK, sound data.
      ROMs .30-.31 are 27C2001, sound program.
      ROM  .65 is 27C512, linked to 68HC11 MCU
      *    Unpopulated socket.



    TODO:
        - dendeg2 hangs on init step 10.
        - The analog controls don't seem to work in landgear. They work in test mode though.
        - landgear has some weird crashes (after playing one round, after a couple of loops in attract mode)
        - dendeg2x usually crashes when starting the game (lots of read and writes to invalid addresses)
        - All dendeg games have random wrong textures/palettes
        - Train board (external sound board with OKI6295) is not emulated
