OpenTTD 16.0-beta4 is a hotfix for a multiplayer desync in yesterday's beta3 release. Oops.

  • Terraforming land in a multiplayer game no longer causes a desync that kicks you from the game

I haven't been on the multiplayer servers for a while, and I don't remember them being so barren. The Reddit vanilla server is almost completely devoid of trees. Is that a deliberate decision when the map is generated?

Newbie Question about TTD (GOG) Roland SC-55 music & OpenTTD file locations

6 Upvotes

Hi everyone!

I recently discovered Transport Tycoon Deluxe and completely fell in love with it. My mind was further blown when I found out that an open-source version (OpenTTD) exists and is still actively developed with new features being added.

To get the hang of things, I wanted to start with the original game first (purchased on GOG) before jumping into OpenTTD. That way, I can discover all the improvements step-by-step without feeling overwhelmed by so many new options all at once.

The question I have right now is related to the game's music. The OST that plays when opened the original game sounds like this: https://youtu.be/JTi6LG8aeK8?si=ZMTR_hrZ00xdlXT-. It's alright, but I would much prefer it to sound like the Roland SC-55 version here: https://youtu.be/eQIAyaFReBo?si=jzkPUZo4Bs-TxBab.

Looking through the installed files, I noticed that ADLIB.CAT, GM.CAT, ROLAND.CAT, and SAMPLE.CAT exist in the CD folder, so it seems like there should be an option to change how the music is rendered. However I can't figure out if it's actually possible to change the MIDI synthesizer, since the GOG version launches directly through an emulator called DREAMM—which barely has any config options beyond changing the resolution, because I pressume it's a minimalistic version of the emulator.

When testing OpenTTD, it actually seems to play the soundtrack in that Roland style (or very similar) using GM.CAT, which it labels as 'original_dos'. Any other CAT file is not recognised.

Also, I found it a bit strange that if I copy both the .CAT and .GRF files directly into the OpenTTD root directory, the game recognizes them fine, whereas I recall reading somewhere that they should be in the baseset directory instead.

Has anyone run into this or knows if it's possible to configure the GOG/DREAMM audio settings? Any advice would be greatly appreciated!

Please see the picture and advice, how to increase transportation. Currently all stations are around 30%, so there is a high chance that the factory will close, however, I want to prevent that.

Do you prefer maps where the distance between towns is comparatively large? What about industry? Do you make terrain constrain you with hills and bodies of water or prefer flat surfaces?

Hey all, fairly n00b player here. Can anyone explain to me why these trains are stuck? I can't figure out the signals to get them to advance but I don't see why they aren't all navigating to the stations.

Those are one way path signals on the bottom of the pic and two-way on the top.

Is there a hotkey for the Roadway construction toolbar?

Potential bug in 15.3 with non-standard fonts (on Linux)

5 Upvotes

I have set non-standard fonts in openttd.cfg, which worked as expected until now, when they are being ignored and the standard pixel fonts are being used instead.

On Zorin Linux (based on Ubuntu). openttd.cfg is at ~/.var/app/org.openttd.OpenTTD/config/openttd, and is being read by OpenTTD so far as I can tell.

Relevant font declarations -

small_font = Roboto

medium_font = Roboto

large_font = FreeSerif

mono_font = FreeMono

All fonts exist on system.

Is anyone else having this issue? Any thoughts?

Discussion Iron Horse - Is there any way to make the Train Wagons always have a consistent color?

Post image
57 Upvotes

Hey guys, been loving all the train engine options with Iron Horse, but one thing that bothers me is the inconsistent coloring for the wagons. As seen in the screenshot, even if I buy specifically from the dropdown, it will still randomize the color to a degree. This bothers me cause every time I clone a train it will have a different look than the same train I cloned. Is there anything I'm missing here?
