Solved Confused Over Dos Games

[voljega]

@dragu well even more confusing, @Cthulhus discovered that you can even put some dosbox.cfg parameters into dosbox.bat
So the following dosbox.bat:

aspect=true
mapperfile=lba1.map

imgmount d .\cd\wackyw~1.iso -t cdrom
c: 
cd WACKY
pause
WW.EXE

will rightly set the display to 4/3 but the mapper file won't be used if dosbox.cfg is not present with the same parameters
@Cthulhus managed to set some parameters for the cpu and for graphics too

Well maybe it's better to separate the two anyway

On a side note, to finish with iso names having more than 8 characters : it seems to work to specify them in dosbox.cfg [autoexec] with the full name but then you also have to use the full path

And in the mapper with an xbox360 I can configure dpad directions with the internal mapper but the keys are then not working in game

@voljega
Yes, you can make alot of operations in the bat file. And create other batch files.
I also find something concerning your relative path story, perhaps it can help you :

[voljega]

@dragu nice but I don't have any trouble any more with the relative path, only with long names

I'll keep it on the side, though

Do you still have dead-zone problems with your joystick?
I try to play on Captain Dynamo and the joystick (which is auto-detected) generate some ghost movements.

Thanks!

Never used this emulator. If you could create a basic wiki to help users to use dosbox, could be awesome

[voljega]

@cotedeporc did yo try to modify timed=true to timed=false in the [joystick] part of your custom dosbox.cfg ? This solved my problem !

But apparentlybthere is no easy way to configure deadzone in dosbox...

@rockaddicted ok i will as son as i'll have tested a little more game, twenty or so (only 4-5 for now !)

[rockaddicted]

@voljega no problem, take your time Thank you.

@Dragu @Cthulhus feel free to complete it

@voljega great thank, I'll read that this weekend

J'ai rajouté un nouveau 'bug' : si on monte un cd en cue avec le bin associé dont le nom n'est pas dos-compatible le cd n'est pas détecté, il faut renommer cue,bin et intérieur du bin et c'est putain de strict, même les majuscules il n'aime pas alors qu'il devrait s'en foutre....

'bug' dans le sens où oui MSDOS pur ne sait pas gérer ce genre de nom mais ça marche sous Windows avec la même version de DOsbox, la 0.74.
Après elle est ptet modifiée manuellement cette version DOSBOX pour gérer ça je sais pas

Feels weird playing old games like Colonization or One Must Fall 2097 with music and sounds as my old 486 SX didn't have any card sound :))

@Dragu @Cthulhus (continued in english to be readable by the greater number)

So I've now tested around 500 games of the ExoDOS Collection (which not be as complete as I thought because Judge Dredd Pinball sure as hell ain't in it !) and I would say around 15% have troubles or are not working.

By far the most common problem (70-80% of all games with problem) is the special mounting of directory as floppy or cd.

In dosbox.bat any command like the following lines , despite path beeing correct always raises a "Directory not found error"

mount a .\floppy\ -t floppy

or

mount d .\cd\ -t cdrom

I didn't try in dosbox.cfg to see if it was working and trying with imgmount returns a "Use mount instead" error
Those commands come straight from ExoDOS collection and works under windows with the same dosbox version (embedded in exodos)

Any idea ?

[Dragu]

@voljega
Its silly question and I dont know if something will change, but do you already tried with slash instead of backslash ?

[voljega]

@dragu no lol i'll try next time i encounter one

[Dragu]

@voljega
I just tried it out on my files, and imgmount was not working with backslash as he expect linux notifcations.

[voljega]

@dragu hmmm whaaaat ? All my imgmount use backlashes ( \ right ?) without problems

[Dragu]

@voljega
I used
imgmount d "\recalbox\share\roms\dos\judgepb.pc\JUDGEPB.CUE" -t iso
instead of
imgmount d "/recalbox/share/roms/dos/judgepb.pc/JUDGEPB.CUE" -t iso
and he didnt found the CD.
Still some mistery for me behind dosbox.

[voljega]

@dragu oh yeah but you're using full path so that seems logical at least.

Was it in dosbox.bat or dosbox.cfg ?

[Dragu]

@voljega
In dosbox.cfg

[voljega]

@dragu ok well dosbox.cfg seems less picky anyway than dosbox.bat which only accept true dos filenames
