VGM max file size?

[SSNTails]

What's the maximum file size that VGMs can be? (and is that while LZSS compressed, or uncompressed?)

I know the SegaCD cache size is 128kb, but are pieces of the VGM just buffered if it exceeds that?

For ZGMs stored in ROM, there's no explicit file size limit. On the other hand, ZGMs stored in the WORD RAM have a limit of about 100KBi.
