[Feature Request] [Bounty] Add custom sprite/texture dumping/injection support #71

Open snekz4 opened 3 years ago

snekz4 commented 3 years ago

Bounty Requirements:

Ability to dump sprites/textures from VRAM

Ability to replace sprites/textures with full-color, high-resolution images that the SNES cannot support natively

Should preferably support use of custom sprites/textures of any size. Must at least support injection of textures up to 2k resolution .

Support for loading texture packs

Random notes for anyone looking into implementing this:

I have this planned (mid-long term) for Mode 7 "textures".
bsnes-hd is already entirely true color.
Backgrounds und objects (sprites) are not handled in HD, yet, but that can be added easily enough.
Performance will be a key issue.
I would not support lossy formats like JPG.

I just threw $30 at it for now. Hope to see this happen!

Would dds files provide good performance?

Added "bounty" label.

The image format is likely irrelevant for performance in the beginning. Doing the replacement mappings every frame will be most significant, I'd guess.
