North to the Future. The next big thing is SNESdev.

But the tools I have become used to don’t exist… so I am making my own. In place of NES screen tool, I have made 2 similar apps for the SNES.

M1TE (mode 1 tile editor) for backgrounds and SPEZ for sprites. *** THESE ARE NOT ROM HACKING TOOLS, THEY WILL NOT WORK WELL AT MODIFYING EXISTING SNES / SFC GAMES ***

M1TE

 

SPEZ

And instead of neslib for cc65, I have made easySNES library for ca65 (assembly only).

See all these projects here…

(example code with easySNES)

Other projects that are worth looking into… Optiroc.

https://github.com/Optiroc/SuperFamiconv

(converts images to SNES tile and map and palette format)

https://github.com/Optiroc/libSFX

(another SNES development library)

https://github.com/SourMesen/Mesen-S

(the ultimate debugging SNES emulator)

My projects will likely improve over time, so keep an eye out for updates.

I plan to write some examples, and eventually make an SNES homebrew game. Stay tuned.
