Boat Race improvements... [Roberto Fresca]
- Changed the game name to "The Boat". - Added year and manufacturer. - Improved the PPIs. - Fixed the VRAM size. - Added bookkeeping, coin, key in and key out for both players. - Added bets, start, big, small and others, but are still multiplexed. - Added coinage and test mode DIP switches. - Added specs and technical notes.
