The fact that you can tell it to not draw the tile makes it more flexible than GDK, you would have to change the entire DATA block to make it black. That flexibility comes at a price though, execution speed(GDK tile engine does not use select case, it uses pre calc's) and expansion (make the tile sheet 24 * 10 tiles) and then enjoy typing all those cases (all 240 of em!). These are no bad things though as OlDos has clearly stated that simplicity is the aim with VSGE, not functionality.
When i complete GDK2, it will be easier to use than the current version, but not by much

. GDK2 is aimed at SPEED and minmising memory footprint! A real headache so far i can tell ya. On that note, how much of the keyboard have you added to the type and sub OlDos? Any chance you could post your latest version? I will do what left as i need to add it to GDK2.
Keep up the good work gang,
John
