Reborn Core Mod for Minecraft 1.19.3, 1.19.2, 1.19.1 and 1.19, is a necessary and essential add-on to make use of certain Minecraft mods. That is, if it is not installed, certain features, as well as some mods will not be able to be executed (in any way).
As usual, complements such as Reborn Core do not add content, since their use is limited to the execution of certain Minecraft mods, and therefore, will require another mod to be functional. Its only function is really to reduce the time to create mods, as well as to make it easier to update them.
The installation is quite simple and basic, and as in all other cases, the downloaded Reborn Core file (the link is at the bottom of this page) will have to be placed in the “mods” folder. In some cases, this folder may not be present, so it would have to be created manually.
As it is logical, Reborn Core is essential for the correct execution of certain mods, and therefore, if it is not located in the “mods” folder, some mods will not be usable.
