Looking for Habbo expert

Hello.
I would like to open a retro server for my region and I have some questions:

- There are many released in the Habbo release section. What I need to download in order to make my own habbo retro server with the best version (in your opinion)?

- What are the requirments of server to open a retro hotel in it?

Thanks in advance

- Phoenix is the most stable but Swift/Plus are the most updated. The safest choice is Phoenix.

- Depends on the emulator and your userbase.
