Frequently asked questions

Server

Can I host a public instance?

Yes. There is no function limitation, but keep this in mind: you may encounter scalability or security issues which I probably won't focus on.

Can I use other port for endpoints?

No. It's hardcoded inside a game and server can do nothing about it.

Can I disable billing endpoint?

Yes. There will be no major consequences even without it.

What ports does Aqua use?

  • 80: ALL.Net, game endpoints and Aquaviewer
  • 8443: Billing
  • 22345: Aime

How can I host this behind a reverse proxy?

Here are some tips:

  • ALL.Net and game endpoints can be proxied
  • Billing endpoint can be proxied but with extra steps: enable deprecated TLS_RSA_* cipher and use self-signed ib.naominet.jp TLS certificate - or simply disable it
  • DO NOT proxy Aime endpoint: it's TCP traffic, not HTTP
  • DO NOT compress traffic: proxy as-is if you can
  • DO NOT use CDN proxy: e.g. Cloudflare
  • Set allnet.server.host in application.properties with your public IP or hostname
  • You may change endpoint ports for internally (aqua <-> proxy), but external ports that are exposed needs to be the same as default (proxy <-> game)

java.lang.ClassNotFoundException occurs when I try to start a server!

Delete exclamation mark character(!) in your directory name.

I want to add custom content data in Aqua database

You can add database entry by hand or your handmade tools. Currently Aqua doesn't have a way to do this automatically. I don't have timeframe for this either.

How can I update to a newer version?

Read the changelog to check breaking changes before updating. Then follow one of these options:

  • Take jar file (aqua.jar) from newer release and replace it
  • Copy your current DB file (data/db.sqlite) and config file (application.properties) to newer release folder

Port 80 was already in use occurs when I try to start a server!

Identity which process is using 80 port then terminate it. Game won't connect to Aqua server if port is different then 80 port, so it is necessary.

Game

Can I use unmodified cabinets or games with this server?

No. This is due to hardened security measures which SEGA made.

Will you add [your wanted game name] support?

It'll be case by case basis. Open an issue if you want to suggest something.

Will you add support for intl version?

I won't work on it myself, but merge request is welcome.

Is the server update is mandatory with every new game content updates?

No, games will still work. However, new content probably not appear in game without so-called "force unlock" and Web UI will not work as intended when displaying new content.

Will this server work with newer version of supported games?

Probably not without update, but who knows?

Game passes connection test but networking is not working

Some game have kill switch for prevent early run before release date (a.k.a "Flying Get"). In this case, BOTH client and server need to handle networking enable flag for avoid this problem. For client part, consult with your source. For server, wait for future Aqua update with new version support.

Team or/and place name showed as garbled characters in game when using non-latin text

Convert application.properties text encoding to UTF-8 without BOM.

Misc

Can I use latest version of Java instead of 17?

Yes.

Can I use OpenJ9 JVM?

While it may work, I can't give any support with it.

Will you share game or update files?

No.

Where I can find game patches or get one?

I won't give any help on this repository.

Why the file size of compiled jar is so huge?

It is because Aqua is using Spring Boot as a base. It's a upstream issue, not something that can be fixed on this project side.

I have a problem with the online aqua server

I, the fork maintainer, am not affiliated with any public hosted instance. Contact to your server maintainer instead.

Can I request developer access to this repository?

Please don't. I'm not hiding anything in the repository and currently no plan to give direct write access to anyone. However, merge request is always welcome.
