How can I change the creature ID by adding it as an NCF file?

Thank you very much, I'll give it a try. I'll post the result here. It would be good to post a list of occupied NCF creature slots. Many slots are occupied; is there a way to expand it from 999 to... 2000? kovt_av ported many creatures from Hannik and others, but they take up space that belongs to the Megapacks.

If you really start filling in the slots (a slot is an ID that, by default, contains a peasant) from 999 to 2000, I'll tell you which bytes in the game's .exe file need to be changed, and I'll also provide an .exe editor, but it's better to look for the version from the respected comrade dredknight – he fixed the bug that caused the game to crash when generating a random map. It's better to expand the range on that version, otherwise, it will be double the work!
