Hi there,
I hope that's the right place for that info.
I remember that one game I had years ago had a stupid "copy protection system" : it does a check if a particular cluster in the floppy was marked as a bad one or not. It should have been marked as bad.
I went here on this website and I found it in your list: it's "Captain Blood" and it says it's "broken". So I gave a look into the DOSBox 0.63 source code and I see that the BIOS function "verify" (of INT 13h) isn't still implemented.
Unfortunatly I can't check myself because I no longer have that floppy with the game but I think that game and maybe some other will run ok if you add that real function... and have the original floppy 😀
Bye

Isn't there an utility to create fake bad sectors in floppy images?

verify has hothing to do with it.

copied:
Captain Blood requires int13-support, so it won't work unless
you use the image support (tried it, seems to work). It uses
int13 implicitly, which made tracing much more complicated.

Ok, it seems to me there are different versions of the game and those I found on the Net don't work with DOSBox 0.63...
... so yesterday evening I phoned an old friend and asked him to see if he could find his copy of the game. I was lucky.
The game is runnig, actually. Here are some screenshots 😀
So I guess "Stargazer" can also update the details in the game page.

Anyway a copy protection is really present in the game so if other copies don't work it could be because of that, uh? 😕
