| ~~Game preset~~ ID? (varies for each game). ~~Incremental, started with 0x10XX values in old releases, newest ones have 0x11XX~~ (~~with XX being back to low values~~).

| Preset ID (varies for each game). A full list of know Preset IDs (shared by WiiU/SNESC/Switch SNES emulators) can be found [https://docs.google.com/spreadsheets/d/1PbIPVA4NpFEXs1zk249aR3FSuBTY3r-ajpTq3dP3GnQ here]

The ROM is then optionally followed by the PCM audio files, by the SDD-1 decompressed graphics data (presumably the emulator doesn't properly emulate the chip because of hardware constraints) and by a footer which appears to be an index for the PCM audio data.

There are no setting fields for specific cart features, and it appears that the emulator has "game presets" stored in its own code, which determine the cart expansion chip and probably more game-specific settings. Each official VC release has a different preset ID in the header.

A similar structure can be found on Wii U, SNES Classic and Switch Mini emulator [https://gist.github.com/anpage/c1085055db0242ea3c7558dab56712a5]
