Fix up the background and road graphical layers game now playable
MAME WIP
15th March 2004: Charles MacDonald made various Hang-On fixes: Fixed sprite, tile and shared RAM (2nd 68000) size in hangon - RAM test works, fixed visibility of 2nd 68000 ROM to 1st 68000, passes ROM test, fixed access to road RAM and shared RAM by both CPUs - road layer works again and added proper emulation of the I/O hardware in hangon: Cleaned up input management, now entering test mode does not crash MAME, there are no specific control hacks for the name entry screen, and the ROM patches are no longer needed.
