Solved Confused Over Dos Games

[voljega]

@rockaddicted It's not related to the emulator, more an Emulation Station problem regarding how it shows folder as a menu item.

Any way, i'll file a bug when 4.1 is released and when there will be a new bug tracking system

[rockaddicted]

ah ok, indeed I miss read. I'll check that on the current master build.

[rockaddicted]

@voljega I tested on 4.1 x86 version with that:

# ls /recalbox/share/roms/dos/test/prince.pc/
CDUNGEON.DAT  DIGISND1.DAT  EDUNGEON.DAT  GUARD.DAT     IBM_SND1.DAT  INSTALL.PDM   MIDISND1.DAT  PRINCE.EXE    SKEL.DAT      VIZIER.DAT
CPALACE.DAT   DIGISND2.DAT  EPALACE.DAT   GUARD1.DAT    IBM_SND2.DAT  KID.DAT       MIDISND2.DAT  PV.DAT        TITLE.DAT     VPALACE.DAT
DESKTOPD.CFG  DIGISND3.DAT  FAT.DAT       GUARD2.DAT    INSTALL.EXE   LEVELS.DAT    PRINCE.DAT    SHADOW.DAT    VDUNGEON.DAT  dosbox.bat

And I have no problem, game boots fine.

@rockaddicted strange.... i wil retry but on my 4.1 ES doesn't show on boot, I tried with a pc game with both dosbox.cfg and dosbox.bat inside he folder

[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.

[voljega]

@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

[cotedeporc]

@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
