Thanks for the link. I'll try those.
I think that there has been some really cool work done on making these devices more versatile and user friendly. The PRS+ is a great addition with some of the EAXACT things I wanted on it. Then I saw some talk on the sudoku puzzle and tried to make it work and failed. It seems as though some folks that are very smart with programming have figured it out and was trying to follow along and add the function to mine and couldn't, as I have no experience in programming.
I read through
https://www.mobileread.com/forums/sho...ghlight=sudoku and here
https://www.mobileread.com/forums/sho...=sudoku&page=3 and don't know how to make it work. Maybe it's something simple that I am missing, but I couldn't find enough info for me to make a useable card for my 600. Any help would be appreciated. Thanks
