Typical to a lot of later Taito published SNES games, this game contains an SRAM integrity check to ensure that the SRAM size is exactly 8KB. If the SRAM size detected is 2KB or less, the game hangs on a black screen before or after the Taito logo due to an infinite loop from SRAM region mismatches with the APUIO registers.
