It makes sense if he has a csync or luma SNES cable, but his console only outputs composite video.

It’s true that 1CHIP-01 revision is expected to have RGB output natively (1CHIP-03 is known to not have it). But depending who you got it from, who knows, it could have a broken RGB encoder, maybe someone tried to mod it but failed, or some rare board variant etc…

You should be able to confirm it by continuity tests with multimeter from RGB encoder to multiout pins, as well as continuity on the input and output of the RGB encoder itself.
