Itchy and Scratchy's sprites are uncompressed, but reuse a lot of tiles in their assembly. Changing their weapons (via the addresses below) helps, and I just ripped from gameplay (with a few RAM tweaks to change their position or weapon, etc), trying to match the tile data as a reference. The title demo helps a lot! You can change the current animation frame for their playing animation, but you can't force animations. These addresses are useful as the first frame for most non-looping animations doesn't display properly, and will only show if the animation frame is set to "255" (or "FF"). Level maps can be found in the ROM at the addresses below, stored as 16x16 'rooms'. Overwriting one with 00 to FF, then going there in-game would net me a tileset, and then it's just a matter of applying that to the map data and piecing the rooms together the right way. I couldn't find a quirk-free method of level warping, often Itchy would end up out of bounds. The most reliable method seems to be reducing Scratchy's HP (found at 172C) to 0 to skip the current level. bizhawk ram address 16c0 itchy x-pos 16c2 itchy y-pos 16CB animation frame 16cc animation animations seem to be tied to 'states' idle (9) can't be moved at all hurt (40) renders you invincible but freezing to animations doesn't seem to freeze animations... just the state. hrmph! 16CA itchy tile arrangement 16f3 itchy weapon 16f4 itchy weapon type? numbers based on title screen, in DECIMAL both numbers need to be set, otherwise the game is prone to crashing (finding weapons: numbers increase by 23) (by default they shoot cannonballs, probably another address needs set) 37 weapons!!
