You should do a video lesson about converting Binary code to BCD because Seven Segment Displays use BCD Code not Binary Code. Also do a video lesson on 1's complement and 2's Complement because arcade games use ADDER Chips and Subtractor IC chips which use a CARRY bit that will add or subtract the binary code which uses 1's complement or 2's complement. The ADDER chips and Subtractor chips are mostly in the graphics section that is moving the character in different coordinates XY or H&V lines coordinates.
@@willsarcadeservice4599 Look at a bunch of arcade schematics because they use ADDER IC chips and sometimes Subtractor IC chips for the XY coordination of the characters. I think the color PROM chips started programming code to have this built in that is why you don't see ADDER IC chips or Subtractor IC chips because the Color PROM chips has programmed code to move the character in different coordinates.
@@willsarcadeservice4599 you should make a video lesson about why arcade game boards use "gated logic" , "latched logic" because the ROM data code is "Unlatch logic" but why didn't the ROM data code make it gated logic and latched logic in the game code?
