Regarding disk space issues, I managed to test the latest patch from GitHub and now the games install correctly (I’m referring to MK3, Pinball Fantasies, and Simon the Sorcerer). The disk space issue is strange, but the most important thing is that it’s fine now. I also tested Syndicat, and it installs without any problems.
I managed to learn from the Vogon forum that protected floppy disks would need an extension to emulate floppy drives. An extension similar to capsimg.dll, which is used by Winuae standalone, or the PUAE core in Retroarch. Although one user mentioned that DOSBox will never use such extensions. Although this is a rather old post, I don’t think anything has changed regarding emulating protected floppy disks. Sometimes a CP game will install but won’t launch, other times the copied files will be 0 kb, and still other times, installer.exe won’t respond at all.
Instructions aren’t a problem, although many games use this protection. The problem is when the instructions can’t be found anywhere online
