* Autoshot : repeatedly press the FIRING button for a couple of seconds, then, hold the button.

* If you defeat the giant tank boss with only the default single shot weapon, you will get the lazer powerup. Lose your existing weapons by, carefully, allowing them to be hit by enemies; you must do this before the tank boss enters the screen. Note : Bomb strikes must not be used to defeat the tank boss, or the lazer powerup will not appear.

* By using your Bomb attack when the score reads 777,000-odd, a 7UP powerup will appear, giving you seven extra lives.

- 21st December 2007: Guru - A huge box arrived today. That 19.75kg box looks mighty impressive, although I'm not sure that all of it is going to be useful. Some could be alt. versions but most don't work so I'll need to dump all of these before I can tell exactly what they are. It contains Thundercade (Taito, Romstar USA License, original) and others. Thanks to Tingoes for sending these out.
