To set tile sizes and format
On the graphics inspector toolbar, enter values (in pixels) for the desired tile size.
Press Enter to apply the changes.
Tip
Some games may use pre-shifted sprites, so you may need to set the tile size 8 pixels wider to account for this.
You may need to play with the tile format to get sprites for certain games to display correctly.
Note
Widths are always in multiple of 8 pixels (1 byte).
However, heights can be in increments of 1 pixel.
The maximum title size is 256x256 pixels.
