41CL How to install CLUTILS-4H

[Ángel Martin]

This may be a version mismatch, likely since you're mixing modules created at different times (and even years).

The CL_Expanded module id#="XPMM" is meant to be paired with the PowerCl_Extreme, id# = "PWRX". Then the Library#4 revision "R" or higher is also required.

You can get the latest revision ROM images from the CL Site, in the : Other Files" area:
