    Arkanoid driver (Preliminary)


    Japanese version support cocktail mode (DSW #7), the others don't.

    Here are the versions we have:

    arkanoid    World version, probably an earlier revision
    arknoidu    USA version, probably a later revision; There has been code
                inserted, NOT patched, so I don't think it's a bootleg
                The 68705 code for this one was not available; I made it up from
                the World version changing the level data pointer table.
    arknoiuo    USA version, probably an earlier revision
                ROM a75-10.bin should be identical to the real World one.
                (It only differs in the country byte from A75-11.ROM)
                This version works fine with the real MCU ROM
    arkatour    Tournament version
                The 68705 code for this one was not available; I made it up from
                the World version changing the level data pointer table.
    arknoidj    Japanese version with level selector.
                The 68705 code for this one was not available; I made it up from
                the World version changing the level data pointer table.
    arkbl2      Bootleg of the early Japanese version.
                The only difference is that the warning text has been replaced
                by "WAIT"
                ROM E2.6F should be identical to the real Japanese one.
                (It only differs in the country byte from A75-11.ROM)
                This version works fine with the real MCU ROM
    arkatayt    Another bootleg of the early Japanese one, more heavily modified
    arkblock    Another bootleg of the early Japanese one, more heavily modified
    arkbloc2    Another bootleg
    arkbl3      Another bootleg of the early Japanese one, more heavily modified
    paddle2     Another bootleg of the early Japanese one, more heavily modified
    arkangc     Game Corporation bootleg with level selector


    Most if not all Arkanoid sets have a bug in their game code. It occurs on the
    final level where the player has to dodge falling objects. The bug resides in
    the collision detection routine which sometimes reads from unmapped addresses
    above $F000. For these addresses it is vital to read zero values, or else the
    player will die for no reason.
