On a bad copy, the following appears at the beginning of the game:
"And yet you have not seen it all !"
It is impossible to play.

On the original game (or a good copy ...), it is possible to pick up the items found on the coffee table (wallet, agenda) and start the game.

If there is a problem loading on emulator, it is a technical problem that I can not answer. Sorry.

My only personal problem with this game that I bought in 1986 is that I still have not seen the end. No magazine gives a complete solution, and to my knowledge, nobody has done, whatever the translated version. Crying

I would check if there any STOP FDD subroutine called twice. I have an issue with machine hanging because of it. Usually it looks something like that:

It hangs in the following DISKROM loop, not shure if he has to be there in the first place,
maybe due to a bad jump ?

7801:
        ld a,(#7ff8)
        rra
        jr c,#7801

@walter, I'm actually allso curious about the end of l'Affaire.

There is a guide in the this topic, but unfortunately is not complete.

This code looks like protection check to me. I would just replace it with NOPs or remove JR C,..

I was never able to finish the game, because long ago I had only German version of it ;)

Very strange, because it works on the following machines/emulators with the same DSK file and ROM's

Real MSX Philips 8250 OK
BlueMSX with MSX Philips 8250 Rom's OK
F-MSX Dos (Yay found my old DoSBoX '\o/ OK

No, strangely enough it does not work in openmsx, any idea what the problem could be ?

I just booted up to see what is the issue and on BlueMSX Philips 8250 game works fine... So issue probably is in the disk image. To see what may be hapening, I put a break-point at 7801 and in my version code never executed from this address.

It would be good to know we're all using the exact same disk image.. Please tell us the sha1sum of your copy.
