Hey guys,
Our friends over at cdiemu.org have a guide for adding a 210/220 switch... Link below.
I am not so much into specific hardware differences. Could someone explain to me what would be the actual result of having such a switch? Does it add functionality, compatibility, ...?

Thanks,

I'd say for developing purposes it's a good way to test both output formats. It appears there are actually specific NTSC CD-i discs (some professional discs and like the japanese CD-i titles.
You can read more about this here: https://cdii.blogspot.com/2007/11/cd-i-is-not-really-palntsc-region-free.html
cdifan gives a nice explanation of the differences.

Hi Bas, I don't quite understand as I don't think there was a difference in output format between 210 and 220. Both are PAL players. Any idea?

There are actually two switches. The 210/220 switch tells the MMC if a CDI210 or CDI220 display panel is connected. The second switch is for 50/60 Hz. It doesn't actually change PAL to NTSC (wrong crystal oscillator and further components missing). However, it generates a bastard PAL60 video output that removes the black borders.

This operation was motivated by the discussion in the following CDinteractive forum thread: http://www.cdinteractive.co.uk/forums/cdinteractive/viewtopic.php?t=2817
In short: it was an experiment, good for some testing but like people above said, not actually fully changing a 210 into a 220 or a PAL into an NTSC player.
