Yes.  The 32k RAM can be mapped to all memory blocks ($0400-$0fff,
$2000-$7fff and $a000-$bfff).  There are no mechanic switches, but if you
hold down stop, 3 or 8 during reset (or press one of these keys in the
menu program), the computer will enter BASIC with 0, 3 or 24 kilobytes of
expansion memory.

The Flash ROM is in-system programmable, so you can select the games
yourself.  I'll probably make a special version of prlink with which the
ROM image can be transferred.  All cartridge games a bit less than 1
megabyte.  All machine-language games and cartridges are about 1.5
megabytes when compressed to a ROM image.  You could add some BASIC games
to fill the entire ROM.
