Heh, it works perfectly in 0.73. I should have tried different versions of dosbox before posting. Thanks so much for your help, I appreciate you taking the time to walk me through this.

Now that it's patched, I can't use the alt and F1-F5 keys to input the GPS authentication, which I don't have since the manual is years lost.

The game is installed in the real C:\dos\gs2000. The downloaded patch is in the real C:\downloads\gs2v85 folder. I mount the patch folder as the c drive and try to install it to c:\dos\gs2000. I have also tried mounting the game directory as C, like I would if I were going to play; then I mount the …

Changed the directory name to gs2000, but the same error still persists.

I'm running the installer through Dosbox, giving it the C:\dos\gunship2000 directory in which I have the game files. I'm inputting the information correctly, but the given error is "Invalid drive and/or directory specified".

I'm also trying to install the update in hopes of that helping, but I can't get the updater to accept the directory I have gunship in. Any ideas?

Ok, now it's just acting out at random. Computer voice informs of target front, everything's fine. "Incoming front" just crashed the game.

I think its because I did loadfix -32 while I was still in Z:\ the first time it played without the crash. The second, I mounted, went to C:\, then did "loadfix -32 gs2000". Could that explain it? I did accidentally do what you mentioned before that though, and the 64 total allocation crashed it …

Ok, tried it again with 32kb and it runs perfectly. Got primary with no crash, and was able to use map view. I'm not sure why it didn't work the first time around, but no complaints here. Thanks for your help...after hours of googling I was beginning to think I'd never find a fix for this.

The only version info I can find is in the Setup, which lists version 469.07 Allocating 32kb runs fine except I can't load the map view. 36 and 32 both crash or lock up. I'm thankful for all of your help, but it's really starting to look like this is just one game that can't be run without some sort …

Loadfix and loadfix -54 both cause a crash due to low memory in dosbox. Are there other loadfix values that might work?

System is Windows Vista 64 bit Intel Core2 E7200 @2.53GHz Intel GMA 3100 with 286 MB available memory, updated to latest drivers 5GB DDR2 RAM Game is Gunship2000, using Dosbox 0.74; issue is game crash due to DMA segbound error upon game voice saying "Got Primary" when primary objective is achieved. …

I tried it with an ISO made from the actual disc, and it works. Thank you very much for solving this for me. How did you overcome the choppy framerate?

Hello, it's me again with the Star Crusader issue. I now have an original copy of the game, thanks to the wonders of ebay. I'm still encountering the same issues, though, namely being unable to install it through dosbox or any other method I've come across. If anyone can help me, I would be very …

I just put up a bid for the CD on Ebay, I'll post again once I get it.

I'm hoping someone can help me with this as I'm horribly uneducated in DOS. I'm trying to install an abandonware game, Star Crusader, using Dosbox on a Windows Vista 64-bit system. I've been told this is impossible, but from what I've read on the Dosbox site, it is possible. I've tried two methods: …
