« on: 2020.October.03. 19:16:53 »There is a Rom function that returns the value of a character given certain coordinates. A workaround is used: the rows of bytes that are found on the coordinates(on text boundaries) are compared with all the ones on the character set until a match is found.
Which is of course not exactly blazingly fast.... That ROM function needs to scan through the whole character set worst case.
