Afterbirth Custom Challenge Launcher
Make your own challenge runs!
Created 9 years ago
This is my custom challenge launcher for Afterbirth.
You can create your own challenge runs and share them with friends.

FEATURE LIST:

-Customize starting HP and consumables
-Choose starting trinket and card/pill/rune
-Choose starting items
-Enemy and boss health multiplicator
-Simple item pool editor
-Load/save challenge runs and share them through codes or files
-Random run generator

The item pool editor is a very simple tool which let's you change/combine item pools. For example you could make treasure rooms contain angel room items instead of treasure room items or you could make shops sell devil items AND shop items.

If you find any bugs or you have any suggestions feel free to post them and they might be fixed/included in the next version. Also I'm not a native english speaker, so if you find any GUI text which is bad english feel free to correct me.

INSTALL INSTRUCTIONS:

Just download the binary and start the .exe file. The tool should automatically detect your rebirth folder. If it doesn't it will prompt you to enter the root path of your Binding of Isaac - Rebirth installation.

Modify anything you want and hit the "Play" Button to start the run.

Using this tool may override following files. So it may collide with other mods which are using the same files:

players.xml
entities2.xml
itempools.xml
gfx/ui/minimap1.png
gfx/ui/minimap2.png

After i deleted this Mod it would still function and that's very odd.
Since it changes the like uhh code of the game or adds files, try finding any of these files in the binding of isaac files
or just try finding any of these codes inside your game

Hey? My game doesn't want to open after i installed it. Crashes everytime. I used it on rebirth, maybe that's why. Help please.
This mod didn't function for me.
Eu dou "play", o jogo abre mas o mod nao funciona, o que faço?
Bruh this is so cool! I love it, keep up the good work!
Thank you for this! this helped me beat the game more easily!
This needs to be updated for Afterbirth+
dont download this this glitches your game and you cant open it
for what version of TBoI it is rebirth? afterbirth? afterbirth+?
the binding of rebirth++?
the binding of rebirth++??

what?
it wont let the game open. it crashes every time. but it is nice
Its says that is for afterbirht,but later says that is for rebirth, but anyway, don't load it if you have rebirth or afterbirth+, I almost lost my game because of this mod
How do you revert it??? I lost my game too because of this i need help
i cant delete a item i put in???
How can I have a custom challenge in challenge from normal isaac after click tab?
And I forgot how to play this mods beacose they do not work.
don't download. this mode ruined my game, i can't open rebirth and afterbirth without my game crashing. 89141 fix your mod
How do i install it i'ts not clear enaugh sry if i'ts just me being dumb ;c
am I doing something wrong? I select my items, but when I start a new run, it loads start game stats, not custom
DO NOT INSTALL!!! I tries to play it, and my Rebirth stopped working!!
If Rebirth does not work, go to the folder with the game then to the resources folder and delete the file named players
I did it and its still not working. well fricc, there goes my OP isaac run .
How do i unistall? I want to download another mod but this one collides with it
it doesn't work game opens then suddenly closes
The challenge does not appear in the challenges or custom challenges pls help
It's not supposed to - it begins when you start a new run
it's glitched, when i tell it to start a new run, it still gives me the items that i had before starting the last run, also, how do i uninstall?
Is there a port for mac?
If so, then where?
I CAN BELIVE IT THIS MOD IS INCREDIBLE
tbh you're probably either using afterbirth+ or rebirth, think this needs afterbirth but not afterbirth+.
This used to be very fun, now it won't load any of the challenges. I assume it is because this mod hasn't been updated since 2015?
Why can't I set a spacebar item?
I tried giving myself Blank card, but that failed.
I was left with an empty space.
You have to have it unlocked I think.
Active items like any of the books, razor blade, etc. don't appear. Everything else works fine but it's kind of a bummer I can't do stuff like razor blade / Isaac's heart
so i cant really start up the challenge so like ill go into the custom challenge of my own but then it wont show up when i start the game? anybody who knows how to fix this heres my discord https://discord.gg/Qy894yV


it keeps crashing for me is it because i dont own afterbirth i own rebirth
only opens binding of isaac and does NOT run my challenge. plz reply if theres an answer for this
no because it is for regular afterbirth, not plus
Your comment contains too many emoticon
mine doesn't work. Why does it keep crashing
How do you get the challenge off if you want to play normally again? And I don't know if reverting will mess up my save files or not.
fwoop don't you love how this can help you unlock characters easily?
Why can't I use this with afterbirth+?
I Just Use this To Unlock Characters and Items
Any chance that this will be able to change the starting stats anytime soon?
My game wont work now how to fix it keeps crashing
When I try to launch the challenge, my game crashes instantly...
Any idea why and how to fix it?
The blank card isn't appearing when I put it in my space bar item slot or just my item slot. PLZ HELP!
.-. idc about coins steal all the coins u want
ay hush
HAY. LOOK OUT
ur ded hush XDDDDDDDDDD
So Its a day for a good day
TIME TO UNLOCK MORE BOSSES
Mega satan or the hush
OR MAYBE I WILL UNLOCK THE CHEST - Mega Satan
Just open ur folder and something might be there and then u turn it on.
next you have to make ur own challenge
save (yes
Revert to game (yes
Then play the game
when im clicking play and then new run choosing the character and then is it just the orginal game
Just Download - SAVE - OPEN
Press OPEN At the corner somewhere
Then Do The thing u want to do
Save game and click save (do a name if u don't have one)
Then click Yes (if it wont show click X)
Then click revert to game - YES
Click Play and u get the game working
(not on ur computer. on CCL)
HAY. LOOK OUT
THE GAME CAN CRASH STILL (only if 1001 items like I do)
Afterbirth and Rebirth only can use this
Does not work for me at all... unless intention is to launch vanilla afterbirth
use afterbirth to download it currectly
I AM CREATING ONE CHALLENGE THAT IS CALLED TRIREMENOPHOBIA
you just need to search "RebirthCClauncher
a lot of people seem to be asking how to launch the challenge so this is how i did it. 1. make a challenge, i set a character as i was not sure if it work with the "any character" setting. 2. press play. 3. get onto a save file make a new run, then choose the character that you set the challenge launcher to.

Sorry if that was a bit confusing
P.S don't make the run to ridiculous e.g 50 sworn protecters as that will crash the game

P.P.S English is my second language so don't judge
So, I was going to download this on mah MACBOOK, but now I realize that I FUCKING CAN'T DO THAT! SHIT!
Haha, this was me on a different computer a few minutes ago. Meh.
Was gonna download the mod, then saw a good little number of comments, some asking how to play their challenge, one saying they keep crashing, a russian person, and other person saying they crashed, yeah, most likely not going to download.
Look back at the top it will give you my advice to get you on the game
WARNING - Only for AFTERBIRTH
So they were on REBIRTH MOTHA FUCKA
How do I actually play the challenge I made?
тиджой спасибо
This is perfect for challenging challenges
Where do i find my root path to my rebirth folder?
i was wanting this a long time ago and i finnaly found it
Great to do real challenges and mostly dumbs runs!
Maybe because you made your run a bit ridiculous? i don't know but thats what happens to me...
the game just crashes even with one item


ok,i create a run,i click "play" and TBOI antibirth opens.
what i i have to do to use my custom run??
The run is your next run, so you just have to start a game and it will be using the items and health and all that in that run.
