Subject says it all. Specifically, I'm looking for 32-bit _signed_ multiplication and division: 32-bit * 32-bit = 64-bit (or 32-bit ignoring overflow) 32-bit / 32-bit = 32-bit (plus remainder) I've found 16-bit routines but was wondering if anyone had 32-bit routines in 6502 assembly handy. Any help appreciated! - Ron Kneusel rkneusel@post.its.mcw.edu
