Recipe for installing additional NV memory for game saves on CD32:

[F0LLETT]

Amigakit offers a Flash/RAM card that can have bigger NV (directed to flash memory) and it comes with a modified nonvolatile.ibrary.

So the support is there already, what do you think?

It also works in a CD32, with A1200 <> CD32 adapter. To use both CDROM and IDE, you need to remove ide header and put it underneath, of course you then need to use a twisted IDE cable as pins are reversed. It works though. It also allows you to create multi configs, which can be switched on the fly.
4MB Flash, plenty for updated kickstart modules / roms and NV files.

However, this is a pretty cool idea. I'm sure I have spoken to fuseoppl on CD32 FB group regarding this.

I don't want to turn my CD32 into an Amiga 1200, otherwise I would buy an A1200, I want my CD32 to remain a regular console, just a little improved

Agreed, but you can disable everything and just use NV Flash if you wanted. Like I said its configurable.
As I also said, your way works and it looks decent, little switch on front. Looks cool.
