Cth/Z monsters - How to mod 'vanilla' to get them back?

[nerolis]

I've been finding myself wanting to play with the Cth/Z monsters, but the option to pick them no longer exists. However, I have read that the data is still in the files. Is there any way I can modify 'vanilla' ToME to play it exactly as DarkGod intended it, except add in these monsters? Basically, I want to hack it to either let me choose the option of Cth/Z, or else force it to always use them, whichever is easier. I've been playing 2.34 for awhile, and am just switching to 2.35 today, so I'll want to do this to 2.35.

You might want to talk to the Module makers about this...

In the birth options you can allow the use of 'joke' monsters, which will allow some of what you want.

For wholesale importation you may be better off making your own module.

[Edit] Looks like Nerdanel and Bucketman have beaten me to it!
