Trog: Trog! NES - Fair PvP hack

A patch that equalizes/balances PvP brawling in multiplayer games (without this patch, player 1 has an extreme advantage).

Also included is my previous patch enabling player two to join on Famicom controllers, and a couple of patches that do not enhance gameplay, but rather modify it in a manner suitable for testing PvP :)

ROM patches included:
famicom2p: A patch that lets the 2nd player use the A button for
joining (permitting use via Everdrive on a Famicom)

fair-pvp: A patch that equalizes/balances PvP fighting in multiplayer
games (without this patch, player 1 has a _very_ heavy
advantage)

nerfed: A patch that removes... basically everything from the game.
Not useful for playing the game, useful for testing PvP :)

mirror2p: A patch that mirrors player 1 controller to player 2
movement, reversing left/right. There is a bug which can
cause player 2 not to stop punching player 1 once punching
is started; this behavior does not appear if combined with
the fair-pvp patch. This patch was designed to facilitate
testing, and not to enhance gameplay.


During the course of developing these patches, the following Game Genie
cheat codes were also discovered:

ZEUAIAPA - Infinite t-rex (1 of 2)
SUXPZKVS - Infinite t-rex (2 of 2)
ATVPTTXZ - Removes all enemies (trogs) from the game. Kinda eerie!
EYSAUTEI - Players only fall if they are invincible
AEKEZAGP - Players don't spawn with invincibility
AAXOAXPZ - Prevents players from picking up powerup items
GAOOGXTE - Prevents players from picking up eggs
PXOKUSPE - Prevents powerups and tarpits - and exits! - from spawning
EOOTSAAP - Enables player 2 to join/continue with the A button
(game genie equivalent to famicom2p patch)
