-// Resolution: between 256x224 and 512x448. Most games used 256x224 pixels since
-// higher resolutions caused slowdown, flicker, and/or had increased limitations
-// on layers and colors (due to memory bandwidth constraints); the higher
-// resolutions were used for less processor-intensive games, in-game menus,
-// text, and high resolution images.
-
-// Maximum onscreen objects (sprites): 128 (32 per line, up to 34 8x8 tiles per
-// line).
-
-// Maximum number of sprite pixels on one scanline: 256. The renderer was
-// designed such that it would drop the frontmost sprites instead of the
-// rearmost sprites if a scanline exceeded the limit, allowing for creative
-// clipping effects.
-
-// Most common display modes: Pixel-to-pixel text mode 1 (16 colors per tile; 3
-// scrolling layers) and affine mapped text mode 7 (256 colors per tile; one
-// rotating/scaling layer).
