Q: Do I need Afterbirth for this to work?
A: No. Inside the folder, you can see there is a "Rebirth only" folder.

Q: Where's Toriel, Asgore and Chara?
A: You installed the Special version. Re-install the mod, but only Install the Basic version, not the Special one, and you'll get those characters.

Q: My game Crashes!
A: Install the mod, then delete Costumes2.xml. Be aware that this might cause characters to change appearence
when collecting some items.

Q: I'm in Snowy/Waterfall and the screen is pitch black!
How to fix:
Go inside resources/gfx/Background and delete the "Black" images. Those being: 8bitclouds_64,8bitclouds_64_black,8bitclouds_642,8bitclouds_643,blue_overlay and orange_overlay.

Q: I see a credits page, but not the Challenge page! Where is it?
A: If you want to see the challenges, just go inside gfx/ui/main menu and delete challengeph.png


Q: Is this compatible with Mac/Linux?
A: As far as we know, it's compatible with mac. It's super buggy with Linux and we plan on fixing of it later.

Q: I found a bug! Where can I report it?
A: Either Private Message me through Steam or the mod's blog.

Q: Can I suggest/submit stuff?
A: Yes! Either go to the mod's blog or post a comment in this comment section.



- The mod can be very glitchy on Linux and Mac.

- Rebirth modding is janky, so expect glitches in the Rebirth-only version.

_ In Snowy Rivershore and Waterfall, the screen might go black, but you can still hear the sound. Read the FAQ, you can find the answer there.

-Bugfix for Mac:

-More reskins. (Taking Suggestions!)

Hi, the link doesn't work well I think cause the site does not work.

ive been wanting to play this for about 6 years now

im using linux,and all the stages are completely blank (the scenario are totally white)what do i do?
adn the items reskins dont work too
Hiii just curious about the new isaac coming (repentance), are you gonna make a mod of undertale on it ? But very good work on the mod, i played like 400h with it !
I will probably update it, but only on the Steam workshop. However I won't add any new content.
I downloaded the mode and applied it, but only the Muppet, Monster Kid, and Songs appear, but other characters are not applied.
Hey good mod man, it´s really cool. But i have a question and i will be very glad that someane could answer me. This mod add or change items or it's only visual?

very good mod, but the sprites doesnt change when we get items, the sprites of the coins are broken, and I dont have the starting items (ex: chara's knife)
anyone have a idea for fixing this?
Welp looks like im going to have a bad time
