Solved Confused Over Dos Games

[Dragu]

@voljega

I read the aspect story back in the dosbox Wiki, as I found that it has only an effect on some games.
"
aspect = true | false
Do aspect correction. It only affects non-square pixel modes like VGA Mode 13h, which has a resolution of 320x200 pixels and is used by many DOS games (DOOM, etc). Recommended as such games were designed for 4:3 displays, and without aspect correction will look distorted and not as the developer intended.
Default is false.
"
So, if you have 640x480 or bigger resolution, no need.

@dragu cool to know but then better leave it to true as it will no effect on games with bigger resolution ?

[Dragu]

@voljega
I am not sure, because it is also written :

aspect: Do aspect correction, if your output method doesn't support scaling this can slow things down!.

So, it seems to have perhaps negative effect on speed. This could be an issue in more recent games.

@substring ah ah ok, so @rockaddicted maybe ?

Sorry dude I didn't have time to test this emulator, can't help you.

[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.

[voljega]

@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

@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!
