Neo Geo ROMs are usually bundled in a zip file. Unzip a game and you'll find a bunch of files. You are interested in S files or C files.
How to get an S ROM file
- Unzip a Neo Geo game
- There will usually be one S file, such as
201-s1.s1in Metal Slug or019-s1.romin League Bowling - Choose that file in the file dialog above
How to get a C ROM file pair
- Unzip a Neo Geo game
- There will be at least two C ROM files, such as
019-c1.romand019-c2.romfor League Bowling, orRBFF1_C1.romandRBFF1_C2.romfor Real Bout Fatal Fury. - Choose those two files in the file dialog above
Bigger games will have more C ROM file pairs. Real Bout Fatal Fury has C1, C2, C3, C4, C5, C6, C7 and C8 ROMs. You can grab any pair, as long as they go together. C1 and C2 go together, C3 and C4 go together, and so on.
What is the difference between C and S?
The data inside C ROMs is for the main sprites of the game: the characters, backgrounds, bullets, etc. The data inside the S ROMs is for the fix layer. This layer is drawn above all sprites and it never scrolls. So S data is for things like the current score, number of lives, etc. The 'HUD' if you will.

Why are the colors so weird?

The sprites are stored separate from the color palettes. There's no good way to get the color data from a ROM without running the game. So an alternating blue/yellow palette was chosen as it allows the different colors to stand out.
