Description

Current article says only .easyrpg extensions are supported.

They are, but the official docs for this core say that it also supports .ldb and .zip.

I've confirmed .zip files do work, just as long as the RPG_RT.ini and RPG_RT.ldb are in the root folder of the archive.

Correction

Extensions: .zip, .ldb, .easyrpg
