"The problem" is that the filesystem image needs to be present in the SRAM before the filesystem initializes itself.

Possibly better ways to accomplish it, but I ended up invoking ALTERA_RO_ZIPFS_INIT() myself after the contents had been copied into SRAM.

e.g. 

#include "altera_ro_zipfs.h"
# include "system.h"
...
...
main() {
...
  memcpy();
  ALTERA_RO_ZIPFS_INIT( ALTERA_RO_ZIPFS, altera_ro_zipfs );
...
  fh = fopen();
...
}
