Subject: BBC B+ 128 question.

Hello,

I have BBC B+ with 128k of ram, OS 2.0
DFS 1770 2.22
Also I have ADFS rom but by some reasons
it does not work with the floppy disk drives.
It looks like it can only work with the winchester
drive. I do not know what this edition  of ADFS is so I puled it out
and now I  only have two ROMs 32k - Basic and OS and 16k - DFS.
My problem is I can not start most of the games on this machine.
Sometimes it even says " you need the original acorn hardware" or
something like that. Most of the times the games just hang and the
machine freze. You have to do the hard reset after that. I tried
the same game titles in the emulator ( beebem ) they work fine.
I know that the memory alocation is different for B and B+
And it has the special registers to manage sideways RAMs and
64K of main and shadow ram but I can not find complete manual
describing the memory issues anywhere on BBC lives or 8BS.
May be you can tell me where I can read more about the memory
on B+ 128.  For now my goal is at least to find the way to
turn B+ into B with 32k for starting all the games with no
problems.
I would really appreciate if you can help me with that.
What is the trick? Do I need to change something in hardware?

Thank you.
Best Regards.

Victor.
