Changes

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 (the emulator doesn't properly emulate the chip, presumably 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, with the exception of Special Chip, and it appears that the emulator has "game presets" stored in its own code, which determines more game-specific settings. The Special Chip can also be enabled by the game Preset ID. Each official VC release has [https://docs.google.com/spreadsheets/d/1PbIPVA4NpFEXs1zk249aR3FSuBTY3r-ajpTq3dP3GnQ/edit#gid=490971147 a different preset ID] in the header. The supported Special Chips are: DSP1, C4 and DSP2.   

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.

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]
