Game cleared! PCM Test (voice samples) unlocked in Sound menu. Trace (video replay) data available for all 17 stages!
STELLAR_DAT.bin should be loaded into Internal Backup.
STELLAR_T01.bin, etc, should be loaded into External Backup.
Note there is no "stage select" function. Loading stage data simply loads Trace (video replay) data into the Sega Saturn's internal memory temporarily. The game must be played from the beginning and cleared in one sitting.
