Solved Confused Over Dos Games

[rockaddicted]

@voljega maybe a bug fixed between last unstable and current master.
Please test again on next stable release once available.
If problem, we'll check that.

@rockaddicted I don't remember where the log is maybe there will be something in there regarding the crash of ES ?

@voljega said in Confused Over Dos Games:

@voljega Tested Tyrian, joystick works but there is a deadzone problem, the ship goes toward the right by itself, is that configurable in the mapper file ?

Ok it was more a sensibility/calibrate problem with the joystick drifting by itself.
So to fix that you just need to edit dosbox.conf, go into [joystick] part and modify timed=true to timed=false

[rockaddicted]

you can restart ES on ssh a check the error message.

[voljega]

@rockaddicted ok worked for me too the real bug seems to be when you have the same *.pc game in /recalbox/share/ros/dos AND in a subfolder of that too, but it isn't very important then

[rockaddicted]

@voljega thanks for feedback

@voljega said in Confused Over Dos Games:

imgmount d .\cd\wackywheels.iso -t cdrom directly mount the iso located there /recalbox/share/roms/dos/WackyWe.pc/cd/wackywheels.iso

Well I was a little kick because it works with 'real' dos name for the iso but not with full name when the command is accessed from dosbox.bat, I saw by adding the pause command at the end of the command.bat, really usefull.

• if i change the line to imgmount d .\cd\wackyw~1.iso -t cdrom it works
• if i rename the iso to waky.iso imgmount d .\cd\wacky.iso -t cdrom it works
• if i leave like imgmount d .\cd\wackywheels.iso -t cdrom I get the error image is not found
• if i try imgmount d ".\cd\wackywheels.iso" -t cdrom, image is not found either

The game launched nonetheless but this is a bother for automatic converting.

Do you have an idea to adress directly more-than-8-characters names from dosbox.bat ?
Didn't try to put it back in [autoexec] part yet

[Dragu]

@voljega
Dosbox is always a 8.3 file naming system, not like DRDOS later. It has just the Microsoft standard.

[voljega]

@dragu so impossible to get more than 8 characters and forced to use ~1 and such ?

(I have seen examples like imgmount d ".\cd\wackywheels.iso" -t cdrom in some dosbox.cfg [autoexec] but I don't think I tested them)

[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

[Dragu]

@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

@voljega

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!

[rockaddicted]

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.

[voljega]

@rockaddicted

@Dragu @Cthulhus feel free to complete it

[rockaddicted]

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

[voljega]

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

[voljega]

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 :))

[voljega]

@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 ?
