Here a bonus that I never shared before, a video of the custom NES tool I've written to generate game data.

It was designed to create an MMC3 ROM and the code was assembled using ca65.

I'll explain each individual tool in the thread.

The animation tool. For whole animation, you can set in which CHR ROM slot in RAM it will be set.

You can also group smaller animation together so they go into the same CHR 1K Bank, reducing CHR bank change.

You can change the algorithm to chop up the sprites into tiles with color separation.

For individual images, you can specify in the metadata if you want to optimize the tiles. For fonts for instance you don't want optimization.

It supported metatile importation as well

The palette editor with a popup to select the color from the color available on the NES

And last the CHR bank editor. Allow to specify banks of CHR data of 1K, 2K and 4K size and specify the source of graphics data to put into that bank.

You could specify an offset so it added tile padding for you.

And the result. We did this project at Tribute from 2016 as a spare project until I left in 2018. Before leaving I had stop working on that NES project to work on a new graphics backend during that spare project for the C++ engine they have at the time.
