HOT DOG Linux uses a custom lightweight Objective-C foundation on top of the GCC Objective-C runtime. The style of Objective-C is completely different from the one Apple uses, everything is basically id.

By design, Unicode is not supported.

Low DPI displays are preferred, since the graphics are bitmapped and fixed in size. The preferred aspect ratio for HOT DOG Linux is 5:4 in landscape, and 3:4 in portrait.
