Concerning overwriting the *.csv files... Maybe add support for custom *.csv files? For example "units-custom.csv". The custom entries are appended to those of the regular csv. In case of duplicates, the custom files gets preference. This way you can safely overwrite the regular csv files without risk of losing the custom entries.

Just an idea. It might need to be thought out better before implementing.

The performance is already a concern.

Truth to be told, the CSV file is here to help people understand the format. You don't need any of them, since the values in there are the same as found in the firmware itself (except for units.csv, where I added some transient monetary units and a cycle configuration).

At some point later, as we get near 1.0, these configuration files will be reduced to the bare minimum, and the ShowBuiltinUnits, ShowBuiltinConstants and ShowBuiltinCharacters will be flipped to be true by default. When that happens, the CSV files will only be there for "extra" stuff, not for basic stuff, which is better for performance.

In short, what I am saying is that your idea is good, but that the configuration files are the "custom" part that you are describing, the non-custom part being the builtin ones in the firmware.

Does that make sense?

I'm curious about something regarding these .csv files:

Does the calc actually read from the FAT disk during operation, or does it access them once (at startup) to read them in, and then close the FAT disk?
