if in WB-ASS2 I type
>page 2,3,0,6
>bload "stars.bin"
Geladen tot: $ABAF
>page 2,3,0,4

then this means that I have loaded the file stars.bin
into page 2, bank 6.
And after that I switch to bank 4 in that page.


Now my question is, how do I make an assembly file
that does the same?
I'm using a load routine to load .bin files into ram

Should i do something like:

ld a,6
out ($fe),a ;switch page 2 to bank 6
call loadfile ;this routine bloads "stars.bin"
ld a,4
out ($fe),a ;switch page 2 to bank 4

???is this the right way to switch those banks, because
i tried it and it sort of worked (but it gives me some
bugs now and then....)

That should do it. If it has bugs, then the loader probably has one. And I assume the code is not in page 2 of course. Also, if you start using DOS2 at some point, you should use the DOS2 functions for mapper access.

Note that bank 6 is not really related to page 2, but just to the mapper in slot 3-0. You can bring up the same bank in page 1 for instance.
