7E0CB0 - Round: 00=Slum 01=Subway 02=West Side 03=Industrial Area 04=Bay Area 05=Up Town 06=Break Car 07=Break Glass
7E0CB1 - Area (Round-Max): 00-02, 01-03, 02-02, 03-01, 04-00, 05-03, 06-00, 07-00

7E0CCA - Platform height in Round (verify if 8 or 16-bit)
7E0CCC - counter for number of continues used
7E0CCE - Platform height of wall or object (drum can, tire, etc.) player is standing next to
7E0CD0 - Value is #00 during normal gameplay, writing #01 forces current level's end (gameplay pauses and HUD floats away) but will get stuck if boss isn't dead, and GO! will continue flashing.
Is #FF while loading new level and screen is black.
7E0CD1 - Value is #00 during normal gameplay, is set to #01 when level ends or during new level map or bonus stage announcement text.
If set to #01 during normal gameplay the timer will stop and the game cannot be paused, but the player can still walk around.
7E0CD2 = #00 until certain bosses die (all except Sodom?) and it changes to #01. This causes all on-screen normal enemies to immediately die, ends the level script and disables the player's hitbox.
Forcing it to #01 during normal gameplay also triggers these effects. Force back to #00 to resume normal gameplay.
7E0CD7 - When GO! -> is flashing, this = #01. Changing it from 00 to 01 manually prevents GO!-> from appearing.
7E0CE1 - Status byte for Sodom's audience. Only matters on level 01-03. Default is #00.
As soon as Sodom activates his code writes #01 to this address, triggering the audience to cheer.
Overwriting it with #01 at any time while on level 01-03 before reaching Sodom will cause the audience to begin cheering.
7E0D00 - Player 1 status 00=not active 01=active. Also the player's direct page index.
7E0D01 - Player 1 status bits? - bit 04=holding weapon
