/* Tecmo System
 Driver by Farfetch & David Haywood

can't do anything with this, its protected and expects to read back 68k code :-(

T.Slanina 20040530 :
 - preliminary gfx decode,
 - Angel Eyes - patched interrupt level1 vector
 - EEPROM r/w
 - txt layer
 - added hacks to see more gfx (press Z or X)
 - palette (press X in angel eyes to see 'color bar chack'(!))
 - watchdog (?) simulation
