I'm a n00b when it comes to assembly, but I was reading the 3d VE lookup tables in the $a1 hac, and it appears to me that if the RPM <800, it gets multiplied by 2, and 400rpm is subtracted. Wouldn't that mean the last cell would be 400 rpm? Someone check me... If so I need to change my definition file.
(there's no way this is going to come out formatted right...)
B893 LB893:cmpa #0x20 ;800 RPM
B895 bhi LB89F ;BRANCH IF > 800 RPM, ELSE
B897 lsla ;MULT * 2
B898 suba #0x30 ;(RPM*2)-48
B89A bcc LB89D ;BRANCH IF NO UNDERFLOW, ELSE
