Bad idea.  Use RES to *allocate* memory instead of just picking arbitrary
RAM locations to use.  The details have been explained many times before, so
I won't reiterate them here.

That's obviously a software bug.  Some obvious possibilities is that the
proper bank isn't selected, or that the same RAM is used by other parts of
the code since it isn't being properly allocated.  Speculating further is
pointless until these issues are dealt with.

It isn't.
