some help with math

as a test i reversed high to low byte in the font structure

unfortunately it worked , and this is supported by the data dumps as shown in previous posts , so to make the font common routine work i would have to reverse all the data stucture for each font chr - which if i dont have abetter option will need to be done

        ' Code for "0"  Asci 48    90 real values _   
@ dw      0x0000,0x0000,0x00FF,0xFF03,0x0FC0,0xF0FF,0xFF1F,0x1FF8,0xF8FF,0xC33F,0x3FFC,0xFC81;,0x3F

If you can write to that area your program could swap the data and write it back,
then set a flag somewhere in a spare EEPROM bit to flag not to do it again.
That’s if you can’t write something to spit it out a serial terminal in the format you want it.
If the pic can read that and also has a serial terminal, you should be able to get it to format the lines as code you have above.
