Differences to the published Master System run.
* Batman uses a black palette and not a purple one.
* Batarangs can be adjusted by sacrificing range for extra power and vice versa.
* You can use a special full-screen attack. The strength of this move is equivalent to 2 regular hits from Powerful mode.
* You don't need to use the grapple just before landing on the ground to cancel out the mini-land stun.
* You cannot cheese bosses 1, 3 and 5 by standing on the far right side.
* Powerups are only extra HP (2, 4 drops) and extra Specials.
* Regular enemies can no longer die in a single hit. Unless you use Powerful and even then some may take 2-3 hits.
* Batman now has an HP bar and not an arcade-style touch something and suddenly he dies.
* Because of this, dying will respawn Batman back to the start of a section and not where he just lost a life. Dying against a boss will restart the entire fight.
* Framerate was dropped from smooth 60 down to a cinematic 30.
* Oswald truck/bus doesn't have any collision and there is no accidental wrong warp to the final section of Stage 5. The good news is that the
no wrong warp route of this can be done in under 7 minutes.
*Number of sections before a boss battle has been increased:
Stages 1-4 (2 Sections in Master System, but 3 for Game Gear)
Stage 5 (4 Sections in Master System, but 5 for Game Gear)
* The grapple can attach to side walls and with creative execution, you can jump out from it, grapple attach it to the same wall to function like a pseudo wall jump.
Route:
Stage 1 - Route 1
Stage 2 - Route 1
Stage 3 - Route 1
Stage 4 - Route 1
Stage 5
For TAS timing, a full screen special should be used on the final hit on Penguin phase 3.
One thing you have to be cautious about is boss battle's HP.
For example, the first boss may die after taking 7 hits, sometimes after 8 hits. Some memory research is required on why some fights are longer than others.
