STARMASTER
• 2 versions exist with both NTSC and PAL. The original versions have a bug in the code that causes the screen to roll. See the bug entry below.
• Pressing LEFT+RIGHT or UP+RIGHT allows you to quickly “warp” in the sector you’re in (helps to either find or avoid enemy objects).
• The Difficulty switches act the same as the TV Type switch. The manual simply says not to use them during a game.
• BUG: If you manage to save all 4 stations on the highest level (StarMaster mode), you’ll end up with a score below 100 (instead of closer to 10,000)! This is the result of a carry overflow error in the score calculation routine.
• BUG: The original releases of the NTSC and PAL carts exhibit a scrolling picture, due to the VSYNC pulse lasting for only 2 scanlines instead of 3.
