Some more info...

It looks like the game uses "Photomotion P8.exe" to play the video.

Here's the game's CFG file:

DEVICE=C:\BACKROAD\SYSTEM\SBPDD.SYS 1 1 5 220

Well, that's an odd one.

SBPDD.SYS has come up once before at Pilgrim Quest - CD Install . Perhaps the suggestions there will help?

DEVICE.COM appears to be available in Can I use a device in DOSBox? .

Hmm I tried loading SPBDD.SYS with DEVICE.COM but it tells me "device driver installation failed". Thanks for the suggestion though. Maybe booting to Dos in Dosbox would work but that seems like a lot of trouble.

Funny thing is the installation program warns you that FMV audio is disabled on SB16(other SB versions have sound). I've tried forcing SBPro2 in the Dosbox cfg but it didn't help.

It's fairly straightforward. There are some instructions at Install DOS in DOSBox .

You can try some of the other alterantives to DEVICE.COM, such as devload (mentioned in that other thread) or perhaps ddloader or loadsys (available at http://www.hiren.info/downloads/dos-files ).

Before you go the route of booting DOS, consider that DOSBox does not support mounted cdrom drives or images after booting. You can use SHSUCDHD to create a virtual cdrom drive inside the booted DOS environment, but it only works with ISOs. If the game in question has audio tracks then that might be a problem if the game insists on having them, because ISOs can't contain audio tracks.

Hello all,

I am new here. Thank you for this nice forum.
I experience exactly the same problems like you Zalth. The game Revell Backroad Racers (Build & Race) runs in Dosbox very good except the sound in ingame videos is missig.
I tried to copy some FLI an MM videos from the CD-Rom to the game install directory \PROG
You can use FLICPLAY.EXE for FLI animations and P8.EXE for MM videos.

The videos are playing fine directly under dos (Dosbox) but here is the same problem - no audio for the videos.

There is a switch /n for the p8.exe player for choosing an audio driver but I did'nt find out how to activate different audio drivers with that p8.exe player.
For example: p8 /nsbpdd.sys cop210a.mm doesn't activate the audio track in the mm video.

I noticed too that the installer informs you that you wont have audio in FMV sequences with the Sound Blaster 16. With every other sound card it should work. I think I remeber I had full sound on my 486 DX4 100 with ISA Sound Blaster Pro back in the days... 😀

Maybe some one has contact to one of these guys?

I think the problem is the missing config.sys option in Dosbox.
You cannot add a config.sys entry like "DEVICE=C:\SPIELE\BACKROAD\SYSTEM\SBPDD.SYS 1 1 7 220" to the dosbox.conf [autoexec] section.
config.sys entries in [autoexec] will not work.
[autoexec] is only for autoexec.bat entries.

Thank you and best regards from Austria,
Reini

you can run mm videos directly from the cd.
example: (E: is my cdrom drive)
E:\BACKROAD\GAME\ENDGAME>e:\backroad\prog\p8.exe e:\backroad\game\endgame\chr440f.mm

EDIT:
okay it seems we really need a full working MS-Dos installation inside Dosbox to get the config.sys audio device running.

I will try this tutorial:
http://www.transmissionzero.co.uk/computing/i … sdos-in-dosbox/

MS-Dos 6.22 installation for Dosbox done but now I need a CD-Rom (MSCDEX.exe?), mouse, soundcard driver which is working with my real hardware in dosbox. Phew.... any suggestions?

Thank you and sorry for my broken English!

It's a bit unusual to see a two-year-old thread getting bumped, but at least you seem to know what you're doing. 😀

As per the above:

In the two years since this thread was posted, experimental support has been introduced for emulated CD-ROM drives when booting DOS. But SHSUCDHD is probably easier for now, assuming the game does not use CD audio tracks.

You are right Jorpho, the Revell Backroad Racers Game doesn't have audio tracks.
Thank you for your hint. I will try this SHSUCDHD MSCEDEX replacement. 😀
Is this the correct download site? http://www.oocities.org/jadoxa/shsucdx/

Cheers,

with newer dosbox builds you can mount an iso (with imgmount) and use oakcdrom.sys and mscdex.exe in config.sys and autoexec.bat as usual.

The only thing is, you can't change CD without restarting dosbox.

I suppose, but http://www.oocities.org seems to be down at the moment.

I haven't built the Mustang yet, but I played it. 😀
