Just a quick follow up, and a question for the list: The original character ROM contains two sets of capital letters, and on set of lower case. Does anyone know why there are two sets of cap letters? Presently I have replaced the lowercase letter set with the new Japanese fonts. Hopefully this was the correct thing to do. A poke 59468,14 should activate them. However you do lose the lowercase characters of course. If you believe I have made a mistake, please let me know. I have uploaded to my iDisk server a binary listing of both the original ROM and the new Japanese version so you can visually see the difference between the two (0's and 1's have been replaced with # and _ to increase the visual contrast) Thanks On Nov 24, 2009, at 5:18 PM, Philip Lord wrote: > Hopefully Ethan can extract something from my Japanese character > ROM, but in the mean time I had a few spare hours and decided to > make one of my own. > > I haven't tested it as I don't have anything to test it on, but I'm > 95% sure it will work.
