Atari Lynx tests

These are just a couple of tests for the Atari Lynx. The blitter seems to be quickest when drawing the full screen width of 160 pixels. In the Galaga test, the background stars are a series of 160x8 pixel sprites. In the Pac-man test, the maze/dots are held as a 160x102 sprite. In both cases it enables the background to be redrawn quickly. By default resource monitoring is on. The first background colour represents the blitter time, the second the CPU processing time. When the background returns to normal it is idle, waiting for the next vertical blank. Option 1 will toggle resource monitoring. For accurate results you need to use real h/w rather than an emulator. On the Pac-man test, option 2 will toggle between 4, 50 and 100 green monsters.
