The issue is that on such small resolution, the way some of the sprites were redone, making the game 4-lv grayscale barely even adds any much improvement to graphics. In fact, in some cases, it actually makes them worse, because of how hard it is to see light gray on the 84+. It would definitively help in some cases, though.

Personally, I've never had an issue seeing light gray on calc with 4 levels. If you go above 4, it becomes progressively worse though.

Do make sure you're ready to deal with all the problems that 4-level greyscale brings, however! You might have to adjust your drawing routines to fit, but it certainly won't look any worse.

Isn't it just DispGraphrr

Well, i use 6MHz anyways, and i plan on letting the user set contrast and interrupt speed to make it look epic, the grey scale

Well, I can let him do everything like thepenguins asmchess, so contrast and the interrupt speed

And I see, Sorunome. I was wondering because before I swear I saw that Axe only supported 2 interrupt speeds, meaning 2 grayscale quality modes.
