@vanderZwan I'd love to read, but I don't think I'll do more than use nametables as compression.

@neauoire Nametables as in nesdev.org/wiki/PPU_nametables? So tile maps, basically?

My ideas involve a few LZ77 variants, which should complement that quite easily

Devil Lu Linvega

@vanderZwan yeah, just indexes to tiles in a spritesheet, and to use Varvara's color byte to handle duplicate tiles that are found in memory but that are flipped x/y.

Job

@neauoire Ok, I'll try and write out the ideas I had in a coherent fashion and then you can tell me if I succeeded at the coherent bit (whether or not you have a use for them is an entirely different concern)

Devil Lu Linvega

@vanderZwan in any case, maybe someone else can make use of them.

In this case, I think you'd have to be somewhat familiar with the uxn sprite format.

Job

@neauoire That's true :)

wiki.xxiivv.com/site/formats.h right? I've read through the docs before, just haven't written something in uxn myself yet.

I don't see a reason why LZ77 based compression wouldn't likely help here. There's a reason LZSS-variants are common on NES and GB/GBA/DS devices nesdev.org/wiki/Tile_compressi

@vanderZwan I can't really load pages right now, but I'll have a look when our connection gets a bit more stable.
