The 0x60 header is followed by the SNES ROM, often altered to replace audio samples with pointers to external PCM audio files converted from the game, presumably to speed up emulation (these pointers can be found by looking for "PCMF" in the ROM, as seen on [https://github.com/Plombo/vcromclaim/blob/master/snesrestore.py Wii VC]).

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.
There are no separate setting fields for individual cart features, and it appears that the emulator has "game presets" stored in its own code, which determine the game-specific settings (such as the expansion chip, and presumably the presence of SRAM), selectable via the preset ID in the header. Each official VC release has [https://docs.google.com/spreadsheets/d/1PbIPVA4NpFEXs1zk249aR3FSuBTY3r-ajpTq3dP3GnQ/edit#gid=490971147 a different preset ID]. The supported SNES expansion chips are: DSP1, C4 and DSP2.
A similar structure can be found on Wii U, SNES Classic and Switch Mini emulator [https://gist.github.com/anpage/c1085055db0242ea3c7558dab56712a5]
