A racing mod for The Binding of Isaac: Afterbirth

speed-mod v1.2

NOTE: Now that The Binding of Isaac: Afterbirth+ DLC has been released, this mod is not needed anymore and should be considered abandonware. Please see the Racing+ racing platform for all your speedrunning needs.

This is a racing mod for The Binding of Isaac: Afterbirth that removes cutscenes and some useless animations. Since it is only a "graphics" mod, it influences the game in only very minor ways, so you can combine it with whatever other mods you want.

How It Impacts The Game

From a strategic standpoint, hardly anything is changed. Here's a small list of things that are:

• Betrayal is now a take. You can also use it to lock in devil deals if needed.
• Dry Baby is now always a take.
• You might not want to bomb out of certain boss rooms that you normally do. For example, Monstro II has a long death animation and most racers bomb out of his room on The Cathedral. But now, if you have high DPS, you might not want to waste the bomb.

Full List of Changes

• Adds a small logo to the title screen (titlemenu.png)
• Removes the intro cutscene (cutscenes.xml)
• Removes all of the ending cutscenes, including the credits (cutscenes.xml)
• Removes all of the boss introduction cutscenes (versusscreen.anm2)
• Removes all of the floor transition cutscenes (nightmare1.anm2 to nightmare13.anm2)
• Removes the fetal position animation at the beginning of every floor (001.000_player.anm2)
• Reduces the jumping in the hole to the next floor animation from 16 to 2 frames (001.000_player.anm2)
• Removes the beam of light animation when going to the Cathedral (001.000_player.anm2)
• Removes the chest entering animation when going to The Chest or beating the game (005.340_big chest.anm2)
• Sets the "shake" animation to 0 frames, which is the animation responsible for Book of Revelations, rainbow poop, black heart depletion, and so forth (giantbook.anm2 + giantbook_eternalheart.anm2)
• Sets boss death animations that are longer than 1 frame to 1 frame (except for Krampus, Uriel, and Gabriel)

Other Notes

• The lowest frame count that the jumping in the hole animation can be set to is 2. Otherwise, the game will soft-lock when the player jumps into a big chest.
• There is around 1 frame of lag whenever the shake animation is supposed to play (with the exception of entering or exiting Curse Rooms). I'm not sure how to fix this without the Afterbirth+ API. However, this isn't really a major issue.
