And this is the subroutine I write to put on big display characters on screen. Too bad I can't fit it in into one screen.
I trust you know what line to change in upper screen in order to have this, by now. ;)
Computer programming is not a sprint. It's a journey. Take your time, do a little bit at a time. You'll get there eventually, having fun along the way.
Here is the third or coloring code screen. The way it's done, it causes jittery screen, but it was done this way so that I can code it one screen at a time. Very useful coding technique for a busy person. :)
The top screen holds your computations. The stripes moves up with the numbers, making it easier to see. It took me quite a bit of trial and error to get it. I'm sure somebody who is good at math can do it easy. Who says you need to be good at math? :p
MPMODEM.PRG is done. It has two parts, and if you want to transfer to a new 3DS, you can just type the MPFILEREC part. Here's the first screen MPFILESEND
MPFILEREC
It's short, so you can just type it in quickly. Transferring Calc84 SpookyMaze (20Kb) takes about 7 minutes. Can it be faster? Probably. I put in built-in delay as to not overwhelm the buffer. YMMV.
