The SuperCharger, it's RAM, yah see?

 

Why not declare a chunk of RAM/ROM to be used as a pseudo wall segment which then you can then use as a mini bitmap frame buffer and draw the falling tile in. Or have an double height wall segment with the "falling tile" in the middle. Then you just adjust the top/bottom pointer to make the tile "fall".

 

Then you just need "tile on floor" and "tile on switch" floor bitmaps.

Thanks for the suggestion - it might just work The walls are a different colour from the floor tiles, but it shouldn't be too noticable on a rapidly falling tile. The pointer shifting trick is already used to open and close the doors. I know that the Supercharger is all RAM, but it isn't very convenient to use and 6K doesn't seem to go very far for a game like this!

Will the falling tiles be at the same horizontal level as the player and other objects? When they aren't, you might be able to use a missile for the falling tile and have its color be "correct". If the code didn't get too outrageous, you could have the game use a missile when a good one was available, and playfield when it wasn't.

In the original game it is possible to knock a tile from underneath, causing it to fall on the players head. This could be treated as a special case, and the player0/missile0 sprite used, but I would have to change the kernel for this. The PF method also has problems as the wall position under a falling tile may not be empty, meaning that it is non-trivial to use wall tiles to represent falling tiles. I am still thinking about the best way to do this ...
