Hello.
I need to use a codepage 1250, but I see that in DOSBox for PL language I can choose only 852. However in manual I've learned that I can load other code pages from some external file :

[codepagefile] can be used to load codepages that are yet not compiled
into DOSBox. This is only needed when DOSBox does not find the codepage.
If no codepagefile is specified, but you place all ten ega.cpx files
(from FreeDOS) in the DOSBox program folder, an appropriate codepagefile
for the requested layout/codepage is chosen automatically.

but here I'm stuck. I've downloaded FreeDOS just for those .cpx files, put them in DOSBox folder, but I have no idea how to use keyb command to find my desired codepage.
