+/* This is derived from toaplan2.cpp, but there are enough hardware
+ differences to keep it separate
+
+ TODO:
+ - verify audio CPU opcodes (see toaplan_v25_tables.h)
+ - correctly hook up interrupts (especially V25)
+ - correctly hook up inputs (there's a steering wheel test? is the game switchable)
+ - serial comms (needs support in V25 core?) for linked units
+ - verify frequencies on chips
+ - verify alt titles, some regions have 'Car Fighting' as a subtitle, region comes from EEPROM?
+ - verify text layer palettes
+ - service mode doesn't display properly
+ - currently only coins up with service button
+ - sound dies after one stage?
