As my first foray into ROM hacking (and 6502 source code dissection), I've been working up a number of hacks on Trog! for the NES. Some of these became game genie codes, some became IPS patches. I've also posted up the (partially) disassembled sources in the Documents area, but at the time of writing it's still in the queue.
Anyway here's a playlist of five videos
showcasing the various small hacks I've worked up.
The latest hack, fixing PvP within the game so that it's actually fair (and fun), has been posted to the ROM hacks area
. It also includes all the others (and the list of ~ a dozen game genie codes), excepting the very latest patch, "Blaze It!", providing for faster/more challenging gameplay.
Hope you enjoy!
