Yes. No more auto detection.

Srecko, I believe the question was 'why not' 😉

Because of conflicts. For example I remember a game which quietly detected Tandy and used it instead of EGA which it also supported. I found out about it only when debugging ...
When there is an automatic detection in a game, it does not expect a computer which knows both Tandy and VGA...
I thing that there is also some CGA and VGA issue with colors (for some CGA games CGA must be set anyway to get correct colours).

OK, Thank you.

So this means I must write different conf-Files for VGA and TANDY or is there a way to change machine type while running DosBox ?

You must use different configs.

Mirek

Think you can also give a -machine option on the command line though

And - finally there is this:

1H:\Programmer\DOSBox
2H:> set DOSBOX_DOSBOX_MACHINE=cga
3
4H:\Programmer\DOSBox
5H:> dosbox
6
7H:\Programmer\DOSBox
8H:> set DOSBOX_DOSBOX_MACHINE=hercules
9
10H:\Programmer\DOSBox
11H:> dosbox
12
13H:\Programmer\DOSBox
14H:>

OK, Thank you very much !

But, eg Railroad Tycoon I, worked with VGA graphics and tandy for sound (which sounds way more better than adlib in that game)

now, i can't have goreous graphics and music at the same time 🙁

I propose force tandy sound on tandy system, but leave option to enable it on others systems

i actually use for now:

Although personally I don't agree with this philosophy, the DOSbox developers try to emulate (to a certain extent) a complete PC of a certain type, rather than lose components. They argue that, since there never was Tandy sound in a VGA machine, Tandy sound and VGA are mutually exclusive. However, I'd like to see Tandy as an option for soundcard emulation, like GUS and SB, but in some thread long ago QBix or one of the other developers explained to me why they didn't want to do that.

jal: there was a preson on this forum who said that he have tandy sound card for a normal pc. Read what Qbix said in the other thread: there are conflicts with this sound card with some games.
