Important update about Duke Caribbean and other faulty addons
@elhobbs , I think I found why some addons are not working.
1) First of all, I tested all maps of Caribbean via user map option: only the sixth one is loaded, less than 200kb in size (verified through GrpStudio).
To get confirmation I tested 4 more user mini-episodes, again via user map option:
2) MSSP: the third map does not load because it is greater than 200kb, the first two (smaller ones) work:
3) One4All: already the first one does not work because greater than 200kb;
4) Orbital2: All are not loaded except the last one, which is the only one less than 200kb;
5) Vermin: none of the maps work since they are all much larger than 200kb.
In my country they say that, in criminal law, 5 clues make a proof, and then I don't feel like trying any others.
So I don't think I am wrong.
I do not know exactly what is the maximum size allowed, above which the software returns to the initial menu, stating "*.map not found" (as it is not loaded).
Is it perhaps a RAM problem?: at this point only the true expert on the subject can confirm or deny this assumption of mine and find a solution.
P.S. as a last confirmation I tried SlayDuke, an old addon of no less than 4 episodes, with maps of size more or less 100kb each: they all work!
