Not sure why you're being so hostile :) Drive c is mounted as whatever dfend defaults it to, which is something something /.VirtualHD/ or whatever. Drive d is mounted as the cd image ISO, which I set up using d fend. So both drives are mounted properly. I've added about 50 cd games through d fend …

Hmm well I'm actually trying to run it without even mounting a directory for the cd drive. I launch dosbox. Mount the cd drive as d: and install the game and run it and get that error. So just simulating an old machine, then I tried mounting d: as the cd image of the Return to Zork cd and have the …

I've been adding a bunch of my old DOS games into DOSBOX, trying both to run straight from DOSBOX and using the D-FEND front end. For the purpose of this issue, I've tried both and get the same error. I've installed dozens of DOS game CDs and havent had any problems yet. This is the first game to …

Can some kind soul help me? I used to use D-Fend Reloaded to run my games. But I switched PCs and am trying to get back into it but I can not get it working as well as I used to. I used to create images of my original CDs and mount them as a drive, install the game, run the game and it all worked …

Sigh.. okay I solved it. Apparently Mission Critical is very fussy about the directory and normally I just associate C with the game directory but it didn't like that, it wants to be associated with the root, which is understandable. Works fine now that I made that change. I'm dumb. Carry on 😀

I'm using DOSBOX to run Mission Critical. Very modern machine and I use DOSBOX to run a bunch of other stuff flawlessly but Mission Critical is giving me an issue. I'm using DFEND Reloaded as a front end but I even tried just doing it via DOSBOX and manually mounting drives etc and same issue. It …

the conf as I showed there WORKS, because the output is changed to surface. scaler seems to have no effect. My question is, how can I play in in either surface and make the window larger without changing Windows resolution, is it possible?

Okay, you were on to something. I tried changing the scaler first back to none and it didn't have an effect. Then I changed output from ddraw to surface and it worked. However, because of that the "windowresolution" isn't changed so it plays in a very small screen. I guess I could change my desktop …

I'd be really surprised if I was the only one to ever have this problem but maybe so. As I said, it has happened on games that appear to use interlaced video. Namely: Gabriel KNight 2 before using the deinterlace patch. Angel Devoid Zork Nemesis intro Lighthouse Intro Around the middle of the screen …

Ah okay.. so basically you don't know of any of the DosBox mount cdrom parameters that might fix/help the issue?

I've had near 100% compatibility with every game I have tried with DosBox .72 but I have a persistent CD problem. Every so often the CD has to spin up, which pauses gameplay slightly (such as voices or animations). This doesn't happen with normal games I play outside DosBox, just every thing I try …

For some of my adventure games that have interlaced FMV, such as Angel Devoid, Gabriel Knight 2, Zork Nemesis, the intro to Lighthouse, etc, when I play them in DosBox there's a big black line in the middle of the video, horizontal. It's like it's a double interlace at that spot. I fixed the Gabriel …
