They are not. The base decorate is just a dump of base ZDoom functionality. Helion only supports the functions underneath that are required to support vanilla and boom features.

It's an ogg file. Helion currently only supports mid/mus formats.

It's out of scope. Helion depends on hardware rendering. Software rendering requires the BSP.

The library Helion uses for pngs is very spotty and has some bugs. Unfortunately, they rewrote the API making it a breaking change and everything would have to be rewritten. It will happen eventually, just hasn't become a priority yet. Any modding using decorate is unlikely to function because it's far from feature complete. This is why Helion will parse dehacked over decorate by default if both are provided like in the case of Eviternity 2. You should use DECOHack so you can write decorate like code that will be translated into dehacked. As a bonus your mod will work in the majority of ports including Helion, instead of only ports that support decorate.

This is because Helion doesn't support changing the viewport on the fullsize HUD yet. There is an issue here that describes it and what you can do to mitigate it. I noticed the perforator issue and have a fix on the dev build. This comes from the fact that Helion will parse dehacked over decorate by default because it's stable and feature complete. However, the weapons are defined in gameinfo with different weapon names causing it to break. The fix is to match dehacked behavior and ignore weapons defined in gameinfo so that the perforator replaces the chainsaw as it does in dsda.

Yes for sure. While technically a separate standard I think it’s assumed to be supported if a port supports mbf21.

Thank you @Redneckerz for the very wonderful wiki article!

In the sound options you can change the pitch. Make sure pitch scale is 1 and randomize pitch is off. There seems to be an issue with how the key binding is reading the characters. The keys should show correctly when typing in the console. I will have to investigate what is going on with that.

There is a Linux build that doesn't require anything to be installed. If you want to build it yourself there are build instructions on the main GitHub page. Glad you are enjoying :)

Helion has the resurrect command like ZDoom (which I admittedly use a lot). You can also give yourself items through the console using inventory.add command. Examples would be inventory.add bfg9000 or inventory.add bluearmor. The same names should be the same from ZDoom decorate. You can bind them to keys too for fun by doing something like: bind F9 "inventory.add bfg9000".

In Windows it’s using exclusive fullscreen to get around the double buffer that Windows started using on all windows since Windows 10. Running the game windowed will get around this but may also create a noticeable lag from the double buffering.

I think someone else asked about this, and yes it is something we would like to add. Autosave writes the save at the start of the next level like ZDoom. Sure, I can add an inverse mouse axis option for the next release :)

Forgot to answer this before. In the hud settings there is a hud scale value that will scale all text. You will also likely want to turn off autoscale hud that calculates the scaling if you ever change resolutions.

Hmm yeah something happened with the Windows package where just these fixes weren't in. I repackaged the Windows builds and verified those fixes are in now.

Helion 0.9.2.5 Patch release to fix issues found in Eviternity 2 and the episode selection missing for Doom 2 when running Sigil 2. Was also able to fix the issue @TheSwordman reported for this one.
