I don’t know how to do that.

Have a look at the YFNZ or YFNX manuals, I believe it's all explained in there.

You'd need a way to transfer the ROM file to the CL. There are a couple of approaches, one based on a java script (Sylvain's the author) and another using a DOS Command prompt utility - CLWRITER.

You can start with a RAM-based setup, and once you're comfortable commit it to flash.

There are no planned updates for the standard PowerCL module - which was superseded by the PowerCL Extreme.

It is highly recommended that you make the move to PWRX (using YFNX).

I’m using YFNP with PWRX. The reason being that if I use YFNX, the TURBO(n) function returns “NON-EXISTENT”.

Well, the combination YFNP-PWRX is not meant to work, different FAT arrangment and also different function set!

The NONEXISTENT glitch was also fixed in the latest revision of PWREXT.
Once you manage do the update you'll have this one solved as well.
