This may be possible if you code your own O/S interface layer. See the following link:- http://www.sqlite.org/arch.html And look at the following source files that come with SQLite:- os_win.c os_unix.c We are using SQLite on an embedded device with the DB stored on Flash (ROM). However we use a 3rd party filing system libray to read and write files to it as if it were a disk. We had to write our own interface layer however to call the filing system library funcs, we called it os_flash.c. If you could write a os_nintendo.c (or whatever) file that would be able to perform the reads from ROM then it should work. In this way you would not use an in memory database but a normal file based database.
