Nice demo of what can be done in pure BASIC. It's a fairly brutal time limitation, 40 seconds to do the warm up level

This is fantastic, I love me some Boulderdash!

Thanks. Well, I only built 5 levels so I had to make them hard so the game doesn't finish too fast

Thank you, I am glad you like it.

@DusanStrakl I'm trying to figure out how you are displaying the graphics in this game. I can't find the place where the color palette is set, how do you do this?

If you look in the Commander X16 docs in the github, there are some registers you poke with RGB values to set the palette.

Yeah I was searching for those in the source code of the game, but couldn't find them!  https://github.com/Dooshco/X16-CrazyBoulders/blob/main/CRAZYBOULDERS.BAS

I am using default palette and 256 color mode for tiles. It is a luxury but since I only use 10 different tiles the whole TILESHEET.BIN is only 10*16*16+2 = 2,562 bytes so not a problem to fit into VRAM.

Well, that didn't even occur to me that you could be using the default palette!  Thanks for explaining.

I suspect the default palette was designed around the limitations of NTSC, it always seemed to be very wishy-washy.

I think that for any kind of real application a custom palette is almost a must mostly because how colors are organized not because of the selection of available tones as such. If you have a tile set or sprites with 16 colors the available colors within one group (16 colors in sequence) would almost never work. But for short demos where 256 color mode can be used it is not bad at all.
