@folly Ah well, I guess I will just have to deal with it. There was some issue like this on DosBox before I changed something in the config file.

Mine is definitely not like yours, it is very off centre really. I am annoyed it didn't work when I changed the RunCommand screen size.

Melt Down works on lr-quasi88, you are right. I was just trying all the movement options, left off the fire button... I think in quasi88, the fire button doesn't work either. So I tried that there, and then didn't bother trying it in lr-quasi88.

Did you ever experiment with lr-dosbox ?

I did, and it seems to work quite good, you know.
Just run .exe or make .bat files. and run this. just like a .cmd or .m3u

@folly I was actually wondering how to use lr-dosbox, since you can't easily use DOS launching games seems quite haphazard.

I've always been able to do what I wanted with dosbox, so didn't feel the need to try the libretro version.

lr-dosbox :
Here I have an example of Lemming 3 :

This is in directory 3D Lemmings Winterland (1995) (eXoDOS) :
lemmi3d -> containing the hd files (no images)
lm3d.cd ->directory containing just 2 nessesary files (no images)
lemmi3d.BAT
setup.BAT

lemmi3d.BAT :

mount D LM3D.CD
cd lemmi3d
L3D

setup.BAT:

mount D LM3D.CD
cd lemmi3d
SETUP

@folly So then you select the .bat files in ES and the game runs?

Yes.

Above example is not the best.
I have a better one.

@folly If anything I'd be more interested in something like System Shock, which uses a CD.

Folly

lr-dosbox:
file structure :

RAYMAN.BAT
cd/RAYMAN.bin
cd/RAYMAN.cue
RAYMAN/<harddrive files>(no image file)

RAYMAN.BAT:

@echo off
imgmount D cd/RAYMAN.cue -t iso
C:
cd C:\RAYMAN
rayman.exe save=C:\RAYMAN

Zering

@folly Are your bin and cue in a separate directory inside the main folder in this instance?

Folly

Yes
And hd files are also in a seperate RAYMAN directory.

Zering

@folly So essentially you're putting the commands in the .bat file you'd normally input into DOS?

So if I created a blood.bat file it would be :

cd blood
blood.exe

Right?

Yes that should work.
You can remove .exe

cd C:\RAYMAN
rayman.exe save=C:\RAYMAN

So I'm trying to figure out what's going on here.
Imgmount is mounting the CD image.
C: is indicating to DOS where to look for RAYMAN?
I can't tell what echo off and save=C:\RAYMAN are meant to do.

Yep

Yep (EDIT: tip from adambegood -> not necessary in this example)

"echo off" -> you don't see the commands while loading (not necessary)
"save=" -> game specific, I think

I also run Philips P2000 on lr-dosbox :

@folly I did not even know the P2000 existed.
You keep giving me things to tinker with! ^^

Cool, isn't it ?

Seems that cas support is now added in lr-mess for Philips P2000.
So I have to try.
But I think display is still monochrome.

DOSBOX mounts /home/pi/RetroPie/roms/pc as the C:\ drive by default.

Dosbox (standalone):
This is also a nice example on how to run, for example, Philips P2000 with a game :

Lazy-Bugs.sh :

#!/bin/bash
/opt/retropie/emulators/dosbox/bin/dosbox -fullscreen -scaler normal3x -c "@echo off" -c "mount c: ~/RetroPie/roms/EmuOnDos/Philips_P2000T" -c "cls" -c "c:" -c "m2000 -verbose 0 -boot 1 -tape games/Lazy-Bug.cas" -c "exit"

Batch (.bat) commands are integrated in the .sh script with [-c "etc...."].
