Status: BAD [6502SP version]

Name: BAD [Show more] Type: Subroutine Category: Status Summary: Calculate how bad we have been
Context: See this subroutine in context in the source code References: This subroutine is called as follows: * Main game loop (Part 3 of 6) calls BAD * TT110 calls BAD

Work out how bad we are from the amount of contraband in our hold. The formula is: (slaves + narcotics) * 2 + firearms so slaves and narcotics are twice as illegal as firearms. The value in FIST (our legal status) is set to at least this value whenever we launch from a space station, and a FIST of 50 or more gives us fugitive status, so leaving a station carrying 25 tonnes of slaves/narcotics, or 50 tonnes of firearms across multiple trips, is enough to make us a fugitive. Returns: A A value that determines how bad we are from the amount of contraband in our hold
.BAD LDA QQ20+3 \ Set A to the number of tonnes of slaves in the hold CLC \ Clear the C flag so we can do addition without the \ C flag affecting the result ADC QQ20+6 \ Add the number of tonnes of narcotics in the hold ASL A \ Double the result and add the number of tonnes of ADC QQ20+10 \ firearms in the hold RTS \ Return from the subroutine
