True!
I corrected this without any result...

I forgot to mentionned I installed CM2 from dosbox after mounting the drives. (in C:\Oldies physical folder)

Hi!

Here is the stdout file written by dosbox when started in "no console" mode and crashes (maybe 7 sec after i launch CM2.exe)

DOSBox version 0.72
Copyright 2002-2007 DOSBox Team, published under GNU GPL.
---
CONFIG:Loading primary settings from config file C:\Programs\DOSBox-0.72\dosbox.conf
MIDI:Opened device:win32
Exit to error: DynCore: illegal option in opcode 0xff

NB: (Wanted to add also I configured sound in CM2 installation process)

I did a memcheck 6000000 and got the following:
"Requested memory is available"

Nice bug report. Short, concise, and with all the required information.

CM2 is difficult. I think I remember a lot of threads here about it. Did you search for CM2?

Did you check the compatibility database?

Also, try a different core setting in dosbox.conf.

I would recommend core=normal as well.

Thanks i tried 😀

I actually found some threads about CM2 and followed them all, but it looks like players who managed to make it work didn't know how (JJJJLLL whatever 😀) or didnt post the information (thanks Cantona)...

The compatibility database says its compatible with 7.1 and an earlier, but I tried 7.1 with same result.

Also tried all 4 settings for core section with no change...

---------------------

have you tried loadfix ?
(e.g

1loadfix
2cm2.exe

i just tried:

launched dosbox, went to c: and typed loadfix
then typed cm2.exe, same consequence 🙁

mount C "C:\Oldies\CM2"

How do you start it if you got that c-mounting? How did the mounting look
like when you installed it?

Good remark. The initial mounting was

"mount c c:\Oldies"

to be able to execute "Install", which is at the root of the CDRom, then i mounted down to CM2 folder so that i dont have to type the cd cm2 each time it crashes 😀

In CM2 folder, there are 2 files u can execute to start the game:
Go.bat and CM2.exe. I use CM2.exe cause Go.bat launches the Intro and the game (cm2.exe) and i've watched the intro too many times now 😉, and the result is the same.

thats the content of the GO.BAT file fyi:
-------------------
@echo off
cls
memcheck 6000000

if errorlevel 1 goto end

intro
cm2

goto stop

:end
echo Not Enough memory
echo -
echo Read HELP.TXT for more information
echo -

:stop
---------------

However the game still thinks it was installed in c:\cm2 and by your wrong mounting it thinks it's in c:\oldies\cm2\cm2.

Nah read up 😉

CDRom: at the root:
CM2 folder
LASERLOK folder
Install.exe

Inside CM2:
Go.bat
cm2.exe

after verification, in my "Oldies" folder (in explorer), theres only 1 CM2 folder with no 2nd level CM2....

Changing the mount-point(s) after installing is a VERY bad idea. Better add the necessary CD \CM2 command to the autoexec-part of dosbox.conf if you are afraid of wearing down your keyboard.

Ok, let me do the whme install again, ill update this post in 2 minutes 😀

Ok, no change at all, the config.dat generated by the Install is the same, so is the behaviour 🙁

Any idea?

I don't think we support laserlock.

you could try replacing dos4gw.exe with one found in this topic DOS Memory Extenders - by Snover and DosFreak

I dont have a problem with laserlock and the game is in the compatibility list, plus i've read some guys saying it works with dosbox (they never say how though...) , saying thanks , bisous, and all the stuff 😉
So i want to be the guy who will finally says to the world:

"it works and here is how...."
and i'll do all the bisous thing as well ^^

I looked at this recently. I think that the CM2.exe wants to read something directly from the CD into the memory occupied by the .exe file, which it then executes eventually. The missing content causes the CM2.exe to run some invalid instructions which causes DOSBox to close.
The Laserlok protection check is inside the CM2.exe, not DOS4GW.exe. CM2.exe runs for a while because of a heavy anti-debugging technique - decrypt one instruction, run with single-step flag set, discard instruction, repeat. Hundreds of instructions, several loops that wait for the timer interrupt, ...

EasyJohn, I'm with you on this mate, need to get this working, need a fix of the first CM game I played. My copy just arrived from eBay today, 🤣
