I've fixed the whip because it was acting very weird. It's not an important part of 100RTBD but I still took a few hours making that whole #igavania special thing. Just so you know, you'll need to get to 5-10-5 and then - usually by arriving from the top entrance and killing the enemy to your right without moving - you input the konami code in reverse (Enter, A, B, Right, Left, Right, Left, Down, Down, Up, Up) and the barrier to the right should break, allowing you to fight a teleporting, fireball launching boss. Then you get the Whip Module that turns your gun into a whip-like attack.
But now that it's done, I'm moving on with the rest of the program, mainly collecting the infopacks in State-5 and all that!
Time spent on the project so far: 429 hours
