Well, I started this little activity in 2006. I have a pretty good working "hardware scroll patch" now running in virtual T!
Recall- * the M100 LCD drivers have a hardware scroll mode * M100 does not take advantage of it to speed things up. * I previously made a patch to the M100 rom that frees up 150 bytes. * I've used most of that free space now to implement a patch that uses hardware scroll. The only condition that this patch corrects is the condition when an entire 8 lines of screen is being scrolled either up or down. Other speed ups are imaginable but are much more complex to implement. I have one last bug that I know of to fix, and when I get that done I will share it so others can give it a try! Steve
