Custom/OG Launchers?

[DaraAmadyura]

The Erupe Simple Launcher works fine for me, but I was wondering if there would be a way to implement custom or the OG launchers for Erupe? The archive site with the OG launchers (this link https://archive.org/details/mhfz-original-launcher ) said it works with Erupe, but didn't go into too much detail for setting it up, besides putting the whole thing into a folder. Is that all there is too it, or do I need to replace everything in the Erupe www folder with the folder of the desired launcher?
