MODE &87 doesn't select MODE 7, it is treated as an unknown MODE and selects MODE 0. All other shadow MODEs are correctly selected. The flaw is in
graphsdl.c -> setup_mode() where:
modecopy = mode;
mode = mode & MODEMASK; / Lose 'shadow mode' bit /
needs to be before the first paragraph.
(Can't do an upload from here otherwise I'd fix it.)
