I know that it can't be changed, I just forgot to say that... 😀
I am starting this topic only because I can't run natively on a Linux box. I put it on the subject and on the message trying to make it clear. 😐
In a few words, I want to know if there's any workaround. If it's a source tweak, I change to the dev forum. BTW, I have changed DOS_FILES value in dosbox sources, but I guess this is offtopic and it didn't worked. 😁
More details about the problem:
The clipper program fails with a "DOS Error 4". I know that it's the "Too many file opens" error. In a windows xp box, it's easy to solve with personalized 'config.nt'.
The real problem is that it was found and solved on a friend's xp box, but now I need to run it on my linux box. 😵
