- Button mappings completely reworked: grey bidding/suit selection buttons classified as keypad inputs and put in correct order, and other buttons as console-standard Start, Select, Button 1-2
- Inputs now read through PIO instead of RAM addresses, making them less hypersensitive
- Manufacturer/publisher is Unicard, as manuals and system/cartridge labels clearly state
- Added release years for some common cartridges
- (nw) Link bbcbc in its own library rather than the unrelated libacorn ("make clean" strongly recommended)
