I'm looking for information on some specific file types from Nintendo's past, particularly CGX, COL, and OBJ. Back in the 1990s, Nintendo used these file types for small, quick animations, but they aren't widely documented. A few of these files leaked online around 2020, and I've discovered some tools like HyperCG-CAD-Viewer and OBJ-Viewer that can help view them, but I'd love to learn more. CGX files are used for tilesets that pull colors from COL palette files, and OBJ files are for positioning CGX tiles in short animations. I've had some success using HxD to figure out the OBJ format on my own, but it's tough without proper documentation or a community to connect with. If anyone knows where I can find resources or any community to discuss this further, I'd really appreciate it!

I recommend looking into vintage gaming websites or archives. There are sometimes dedicated sections for Nintendo's development tools and file types. Additionally, joining a Discord server that focuses on game modding or retro game development can connect you with people who might have worked with these files.
You might want to check out places like GitHub or forums dedicated to retro gaming. They sometimes have hidden gems like project documentation or user-created guides that could provide insights into CGX, COL, and OBJ files. Also, don't overlook YouTube tutorials; some creators delve into programming and file structure analysis that could be really enlightening.

Thanks for the tips! I’ll definitely check those out. Discord sounds like a good place to start for discussions too. Appreciate the help!
