There's two types of VC titles: regular VC titles, and dedicated GBA VC titles.
Regular VC
Regular VC titles: an emulator application + VC ROM in the NCCH RomFS(among other things in the RomFS). The emulator build includes support for all supported VC platforms, not specific to just the included ROM platform.
This emulator includes GBA support, however the GBA emulation for this this is somewhat slow. This was presumably implemented before AGB_FIRM was.
Unlike Wii VC, the 3DS VC ROMs for NES use the "TNES" header.
RomFS
- "rom:/rom/" This directory contains the ROM file(s). Filenames used under here don't matter: the filename is determined by the emulator app by doing a directory read.
- "rom:/shaders/" This directory contains GPU shaders used by the emulator app: .shbin, .csdr, and .obj.
- "rom:/VCM/" This directory contains graphics, audio, and text used by the emulator app.
- "rom:/agb.bin" GBA BIOS.
- "rom:/buildtime.txt" Emulator app build timestamp.
- "rom:/config.ini" Emulator configuration .ini, contains sections for all supported 3DS VC platforms.
- "rom:/<rom_name>.patch" rom_name = filename from the rom directory. This .ini contains patches for the ROM.
- "rom:/shader.shbin" GPU shader.
GBA VC
GBA VC is run by AGB_FIRM. RomFS isn't used for GBA VC titles. The NCCH ExeFS contains the same files as a normal application. The ExeFS:/.code contains the GBA VC ROM.
