Anyone ever use yy chr for MD graphics?

It has a graphics mode for just about every game system up to the GBA including the master system, game gear, and genesis/md. I'm trying to figure out how you would go about getting the graphics from it to a G/MD rom. There isn't much documentation though because the author was Japanese and most people use it for sprite editing SNES games. If I could figure out how to use it for MD games it would be a great sprite editor. Anyone who wants to take a look can get it here:

Just scroll down to the bottom of the page. There are two versions. You'll want the yychr99 download.

Hey, that editor looks pretty good. I've never heard of it before, but it seems to do a pretty good job. To set it up to work with uncompressed Mega Drive tiles, do the following:
1. Set "Graphic format" to "4BPP MSX(/Genesys/MSC)"
2. Set "Pattern" to "Normal"
3. Set "Zoom" to "x16"

Yeah, it's pretty easy to use. I just wish I knew how to use the save output. It looks like it saves it as a .rom file, but I'm not sure how this relates to genesis roms if at all.

It would make a great graphics editor if there was a way to convert the file to a resource to be added during compiling.

What YY-CHR does as an editor in regard to the Genesis graphics that general purpose graphics editors aren't capable?

I mean, for me it seems way much easier to make a 16-color bitmap, and convert it with a command line tool during build process.

If it would support multipalette (and/or two layer) images with nametable generation, that would make sense - that's what is not very easy to achieve with general purpose graphics editors.

I like the layout of the editor, and the way you can use palettes with it. The more I play with it though the more it's limitations become apparent. You don't have as much control over the palettes as it seems you do. It would be nice to have a graphics editor like Graphics Gale that would let you build and manage MD/Genesis specific graphics. I think yy chr was originally intended for editing NES chr rom files, and that's the output it works in.

It seems like it would be a headache managing palettes for a large game without some kind of editor.

Graphics in genesis game are often compressed so it's difficult to see it in an graphics editor.

With YY-CHR, you can save/load a bitmap file (take/paste snapshot) if you prefer used better editor (like photoshop, gimp...).
