The latter. I support this, but it does no good when no one uses the format. The most prominent databasing effort will not include any additional files. Not even metadata, they're missing the coprocessor firmware required to play games. I wrote about this a few years back here ( https://higan.byuu.org/firmware https://higan.byuu.org/firmware ), but fair warning it's a bit rantier than my recent articles ^^; I've just taken a shotgun approach recently: supporting games split into multiple pieces inside folders, games inside ZIP archives, games in merged files to a single ROM, games with external firmware in a separate subfolder, games played by an internal database, games that have an external manifest to describe the PCBs, games played by heuristic detection, and games that fall back on less accurate high-level emulation instead of not booting at all.
