Mondial Relay is the most terrible shipping company! Now that that’s out of the way: I finally managed to receive my line voltage simulator so my #SEGA #Dreamcast is finally online again! Installed #Dreampi on my old first gen B model #RaspberryPi, found the required USB modem and bought the line voltage simulator from Dragoncity in France. First try and it worked straight away!
This is so cool to finally be able to play online again with the DC.

Success! We are officially online in Phantasy Star Online on the Dreamcast with my mutant patched version of the DreamPi gateway.
Definitely think there's gonna have to be a stream or two [re-]exploring this game <3

CW: lots of nerd talk about dreamcast and phone lines with dubious delivery
In the service of totally overdoing some #Dreamcast #RetroGaming, I've successfully patched the #DreamPi gateway to be less useful. Buckle up, because this is a kinda long post with little in the way of delivery. :bec_smug:
Normally the DreamPi throws its modem into voice mode, plays a dial tone to fake out the dreamcast, listens to the digits dialed, and then switches to data mode and kicks off a handshake. Stays off-hook the entire time.
This makes sense if you're using an electrically-simple Line Voltage Inducer and a straight connection between the Dreamcast and the modem for minimum part count get-up-and-go. It's actually a really clever workaround.
My tweak adjusts the modem behavior such that it stays on-hook until it detects an incoming ring, then answers and jumps straight into data mode.
This change was made because presently we're using a Valcom DLE-200B phone line simulator which does provide 'local' tone, ringing voltage, and ringdown.
This necessarily means that we lose out on capturing the dialed digits, but it turns out we don't need those at all for pretty much any of the PPP-based games with central servers, and I'm not interested in playing anything outside of that scope.
So now we have a dreampi that can only work in PPP mode and it requires a line simulator to work correctly. Why?
All, ultimately, so that we can hook the DreamPi and two dreamcasts up to a TDM-based #PBX instead of the line simulator, wherein either of the latter can dial the former, thinking they're dialing Dreamcast Online Services. It goes through the whole ring-in process, which terminates at DreamPi, handshakes, and tunnels to Dreamcast Live -- getting us the goods.
And there's lots of Friday left to go :3

There's a new way to play Dreamcast games online: with a taisen cable! It's thanks to eaudunord's new tunnelling script — find out how to set it up for yourself in Gregori's story:

@thorsten Doch, aber die Community hat sich angeschaut, wie die Onlinefunktionen der Spiele funktionieren, sie nachgebaut und eigene Server wieder online gestellt (https://dreamcastlive.net). Mehr zum #DreamPi gibt es hier: https://blog.kazade.co.uk/p/dreampi.html

@HenkGoth Die Community hat einige Server für die DC Spiele wieder bereit gestellt (https://dreamcastlive.net), bei einigen funktioniert dann auch der BBA. Die meisten funktionieren aber über #DreamPi (https://blog.kazade.co.uk/p/dreampi.html), eine spezielle #RaspberryPi Distribution, die mit einem USB Modem an die DC angeschlossen wird und dann die Einwahl der DC ermöglicht.

@thorsten Ich habe mir jetzt einen Broadband Adapter geleistet. Zwar ziemlich teuer, aber man kann ja noch online spielen (notfalls auch per #DreamPi und Modem), aber ich versuche auch ein wenig damit zu programmieren.
Ansonsten hat meine Dreamcast schon ein GD-Emu samt DreamPSU und den Noctua Lüfter Mod drin. Den Akku kann ich mittlerweile auch leicht auswechseln. HDMI könnte in Zukunft noch dazu kommen 🙂 -
Things I wish I had time for:
- #Dreamcast accessory that makes the system think it’s talking to a modem but it’s actually a UART to IP bridge, but without the analog phone bits that are required with #DreamPi. Make this accessory have an expansion header for someone to also attach a BBA emulator to the bus.
- hardware hack for the #PCjr to make #EGA modes that are feature compatible work by mapping memory and implementing registers (and also redefinable characters with shadow RAM)
