Secondary video window

General information and assistance with DOSBox.

Secondary video window

Postby kalpha » 2010-2-06 @ 19:19

In this posting
viewtopic.php?t=7745
under the video section there is
<<
Secondary video window for DosBox monochrome support. Some games also had the option of outputing monochrome to another monitor for debugging purposes.
>> >>
I interpret this as two SDL windows on a VGA monitor one emulating CGA/EGA/VGA and the other emulating MDA/Hercules monochrome.
Is this implemented, planned, not likely ?

Much effort for the two or three people who would be using it

<<i see no use>>
I translate that as
"I see no particular use to myself or anyone using DosBox in only the ways I believe in."
I think the Wishlist posting made quite clear some practical "uses"

<<Much effort for the two or three people who would be using it>>
ouch

Thanks guys, while I am one of the two or three who could make serious use of such a feature, I appreciate you are not only the ones who know the underlying design and code of DosBox but are also the central navigation system of DosBox.

give my regards to Martin please.

It's not like we'd just write
Code: Select all
VideoAdapter v = new VideoAdapter(MONO);
dosbox.add(v);

Kalpha, There's nothing preventing you from implementing the feature yourself and then submitting it for integration into DOSBox.

Yeah and we got to do better things than implement something which only
2 people want just because they want it.

Apologies up front I think my babel fish is still grumpy.

I would like to, but unfortunately
1. I currently do not have a lot of spare time
2. h-a-l-9000 says that it is much effort (which with #1 kinda rules it out)
3. I once suggested the adding of a (missing) std vesa text mode to the int10_modes.cpp and was greeted with something along lines of NO it will add too much bloat (64bytes), does not sound like it is useful for games, DosBox is for games, ......

So along with all the other negative and terse comments from the core, it is hard to get the motivation to expend "much effort" on something that only two people want and will probably be rejected even if it was submitted.

One day my MDA monitor or card or unit still compatable with it will die, but hopefully my current needs for it will have either evaporated or one of the other possible avenues will be more supportive and I will find the time to spend much effort helping those friendly folk. Sheesh I never said DosBox must or should have, I only asked if an item on the wishlist was ever progressed.

64bytes for some useless vesa textmode is definitely too much.

BYTES wow thats small by todays standard, When say it like that wd it makes you sound ass-holish. i assume there is a need for it but we aren't being led on to what it is it may be pure developmental use, i've seen the more often than not, i don't see why another community shouldn't go up with a different version of DB for dev use.

Yeah.

Whatever you're trying to say with that, you're surely right.

alright i get the point but, may as why is 54 byte to much would it cause significant lag? I was saying maybe i has real need for that he isn't telling us about.

we aren't speaking about lag.
it is something that can influence compatibility aside from being not needed for games.

Well looking at what he posted it must not be that much of a priority so I wouldn't feel too bad. :)

<<64bytes for some useless vesa textmode is definitely too much.>>

the 20+ users who are using for productive work do not think it is useless,
but then most of them are on dosemu which supports it out of the box.
For the others we have had to re-compile DosBox with it in, otherwise DosBox would be useless to them :)


re the dual video, that would be seriously useful for me,
but this does not seem to be the place to be serious or useful :--)

You sure you are in the right forum, you sound far too rational.

Again DOSBox has different goal than DOSemu. DOSBox primary goal is GAMING. DOSemu is for pretty much everything DOS related.


If DOSemu works for you then go use that.
If DOSBox works for you then use that too.

If you want a feature added to DOSBox that the devs won't add because it doesn't fit with DOSBox goals then download the CVS, add the feature and compile. That's the beauty of opensource. The devs don't have to agree as long as you stick to the terms of the license.

Those 20+ people should REALLY think if they need to depend on an emulator
that targets dos GAMES and if they do they are screwed anyways imo.
