About this Mod

ModTitle

So, Cor's Hardcore Additions Mods is the downport and rework of my original 1.21.10 Hardcore Challenge Mod! The inital 1.21.10 mod was based off an early version of the WaterBailey-Discs Mod, just with a different catalog of discs! Otherwise, it was pretty much the same as the early versions of the WaterBailey Mod

Due to the 1.21.10 iteration being so out-of-date compared to v1.0.6 of the WaterBailey Mod (and with that crashing server) i opted to rework and rewrite each mod from scratch! Talking merging the original disc list from 1.21.10, combined with all the features of WaterBailey v1.0.6, and made to NOT crash servers when the block menu is opened!

I decided to work out the Hardcore Mod first since I could always get the logic side crossed over between mods, but it did let me adjust the look and feel visually to match what I had in mind for this iteration!

The Disc Creator Menu uses roughly the same texture as the WaterBailey v1.0.6's Menu, but expanded to feel less cluttered! But with the added features of an expandable categories tab to the left, and the lyrics button now poping from the bottom of the screen!

These 2 screenshots are of what v1.0.1 has to offer! More to come in later versions!

This mod was made to be used in a custom modpack that my friend Evil has made for me! Fortunately, I was able to have it see the other mods that is featured in the modpack that offers discs! These discs are stored in different categories, of which there is so many of them, that I had to make the tab contain multiple pages!

The Category Tab and Lyrics Button are both inspired by Undertale's style! I was a bit obsessed back in the day lmao
