When I watched Richy Cream's Slap Fight recording (nice work by the way Richy :)), there appears to be a 'secret' way to powerup in that game as too which I never knew about when I used to play it in the pub. Although it requires a bit of skill to do you just hold fire for a while at the beginning of the game then when you die, you warp ahead and get full powerup.(posted 9099 days ago)And what about Gaplus where you can let the whole first wave get into formation, shoot the 2nd from the left on the bottom row, then ram the special ship as it dives down the left in order to get a better ship for the rest of the game. Ok, you can probably take that one for granted that it's allowed but there could be hundreds of games where the programmer has built in a 'back-door' which we will never know about.
