Demo compatibility for Boom and MBF?

[grendelw]

I know there's the -vanilla parameter for vanilla, but I was wondering what the best way was for ensuring demo compatibility with Boom and MBF? What settings should I use under compatibility options?

[Edward850]

Currently, Eternity is not equipped to record Boom or MBF compatible demos.

That's too bad. Thanks for the heads up.

 

Is it a lack of compatibility for the demo format, I guess?

[Edward850]

Well it can play them back to some degree of success, but it's currently not intentional. As such, it could record one right now (though I don't know if the demo manager can set up the header), but even with the right compatibility flags, it's not guaranteed to be a playable demo outside of Eternity (as in it would desync in actual Boom/MBF), and thus not worthwhile or ideal. Especially if the compatibility improves, the demo would be effectively orphaned.

Interesting. I guess I'm still juggling source ports, then lol. Thanks.

Wait. Currently the support for playing BOOM and MBF demos is proven to work by extensive testing. There are a few notable exceptions caused by PrBoom's failure to fully mean -complevel 11 = MBF in some very specific cases (e.g. BLOCKMAP building), and people actually using PrBoom+ or whatever to record BOOM and MBF demos nowadays (due to the lack of advantage of running the originals on DOSBox; it's not even like vanilla DOOM due to crap music quality).

 

Recording however is only supported to vanilla DOOM yet. We haven't got around to adding such support for BOOM or MBF but technically it will be doable. The added complexity is that the ports, unlike vanilla, let you configure the game extensively.

Pardon going off-topic here, but are you referring to BOOM/allegro handling OPL music here, or to DosBOX playing MIDI via MS Software Synthesizer out of the box for most people, or something else? I am very curious. 

[printz]

The BOOM/Allegro instruments which get heard through DOSBox, which now is the way to play the old executables.

 

Also other glitches, such as the reversed stereo.
