Indeed. Some people cringe at games larger than 2 KB, though (even though they have SE calcs). The good part tho now is that the tile data wouldn't use any 8xi file and the game code would most likely be smaller and not split as much into sub-programs.

Crude 160x120 rendering of Reuben battles, missing several elements. Of course this just re-uses old but colored tiles and an extra menu inspired from the papyrus logo in the Reuben 1 readme:



And updated sprite sheet



Now that I think about it, if such game was made it would be a crazy amount of graphic data with all those monsters

Mmh not really. 2^n colors can be stored in n bits. I remember Megaman made by a few sprites. You maybe can outclass color restriction by sampling your sprites in smaller parts (in preference repeatable)

Well I was talking about xLIBC actually (built-in Doors CSE . xLIB only supports 8-bit colors (using its very own palette). I could easily change the color of each monster sprite when I want, but in xLIBC BASIC doing such pixel test through the large sprite would take a minute or so.

Doesn't xLIBC support palette swapping ? That'd be a neat feature to ask tr1p about.

Sadly no it doesnt, it might not be easily achieved either im afraid.

There is however LOADSINGLETILE which enables you to copy HEX data for an 8x8 sprite to a tile slot in TEMPRAM ... I wonder if that could be used?

Lower color modes with custom palettes would definitively be nice, though.

Yeah that's what I was talking about. Color indexing. Like on the NES but less limited.

Thanks. By the way so far most of that graphical content is almost in calc format. The 4 picvars are in 8xv format (basically the sprite sheet split into 4) and the 4 maps forming the big one above are in .asm files (the top part misses the sides because it's 32x32). I'll have to ensure that they were properly converted, though, before anyone can even use them. Also I think I am missing certain important tiles, so what I might do is scrap the black cliff corner tiles to make room for others. I also had two unused tiles on the overworld spritesheet but if I added a floor tile I would definitively need to move some event tiles around.

Wow, that is quite a lot!
Looking good
