I was specifically asking about the TILT function with or without the arcade display.
Yeah the secret boss is not a big deal for me anymore, apparently it was an Master System exclusive that somehow got ported to the X68000 ( duh I guess ), and later the PS2 version, also includes this.
You know what I don't like about this game, the BONUS CAT, that appears in the middle of a stage, from time to time, that reminds me of "falcor" ( if that is his name ) from Never Ending Story. I was just wondering if SEGA ripped that from NES, and then reused it in, Phantasy Star. While I also know PS, basically uses references from various sci-fi element series, such as "Heavy Metal" and the flying chicken. Seeing that BONUS CAT, appear out of nowhere for the first time, is what amazed me about this game, next to the super fast robot bosses you see the first time around
