There is another repository called 7800tools. It contains sprites7800 subdirectory.

I did see this repo, but the only yaml example I could find was about a single sprite, not a series of tiles.

No, unfortunately the doc is still missing. I'm currently refactoring the examples. In the process, I'll try to add some docs and explanation. In the meantime, don't hesitate to ask for help.

Thanks. I've been trying to modify the example_tiled2.c example to use my own 8x16 square tiles (160P mode), but trying to add my own tiles gives some unexpected results. And I'm not sure I exported my tiles properly using sprites7800. Or did I take the wrong approach? Note that I am not interested in sparse tiling, regular tiling works well for me.

OK, I've finally been able to figure out how to generate the proper tiles and get a proper tiling system. It took me a while to realize the tilemap needs to contain the tile ID times two.

My next question would be around sprites: what's the best way to dynamically determine the sprite to draw when calling multisprite_display_sprite (e.g. use different versions of the sprite when a character walks)? I looked at the include files and found a bunch of sprite functions (BTW what's the downside of multisprite_display_sprite_fast vs multisprite_display_sprite?) but nothing which takes an offset inside the sprite sheet.

I tried declaring an array of pointers containing my_sprite, my_sprite+32, my_sprite+64, etc. but the compiler doesn't seem to like this.
