how is this done? im guessing sprite overlaying but is there a quicker/easier way? i.e in software? as overlaying more than 1 sprite with 4 colours would involve multiplexing, no?
like on the nes where it uses tile to draw the lines and circles, etc for elite. had a look on google but nothing. i need a program that allows me to store the numbers as data statements, etc and it just does it.
ive had a look online and have found one site but there are no gerber files for it.
