Reicast Libretro has now gained modem and PPP support. It leverages which makes it possible to still play these games while their original servers are down. Grab the latest core from the buildbot in order to use this! It should work on Windows, Linux, Android, and potentially even macOS seamlessly without having to input an IP address, thanks to true zero-configuration multiplayer! To our knowledge, this is the first time a Dreamcast emulator offers true zero-configuration multiplayer support like this. Demul requires a complicated TAP driver/OpenVPN configuration, and modem support was not implemented yet since the last time we checked.

How to configure online

In this video, I will boot up one of the games that allows you to set your ISP network information. You will need to do this before online multiplayer will work in Dreamcast games such as Phantasy Star Online.

One of the games that lets you do this is Quake III Arena. Other games that allow you to do this include (but are not limited to) Ooga-Booga and Toy Racer.

Input any username and password combo you want, and only input a local phone number. It can be completely bogus, it can be 666 or 888, whatever you want.

After that, you press Dial. These details will now be saved to your NVRAM, and from there, this same ISP info will be used for every subsequent multiplayer game onwards, such as Phantasy Star Online.

BTW – if you are on Windows, you might get a warning at some point from Windows Firewall if you want to allow a connection – select ‘Yes'.

Phantasy Star Online gameplay footage

In this session, you see me and flyinghead meeting up in a lobby in Phantasy Star Online and doing some hunts together! We are both using the same version of Reicast Libretro inside RetroArch.

As you can see, online works surprisingly well! All kudos to flyinghead for implementing the code necessary to be able to emulate this!

Hopefully in the near future we will have keyboard and mouse support to complement all this! It is already in flyinghead's own branch of reicast right now.

Awesome, I loved Reicast back when it was new and impressed that I could play PSO on my ouya at like 90% speed, giving it online access is great!

I was going to write a manifesto of where I think Dreamcast emulation should head towards, and this was number one on the list.

Next on the list was to integrate wii remote and dolphin bar support to emulate motion controllers like the fishing rod and samba de amigo maraccas.

With a little work, you can already get the wii remote and dolphin bar working as a light gun substitute for HotD2 and Confidential Mission.
