Apparently it is 32bit-only and doesn't support mds+mdf while I still have some and some games on Archive.org come in this format. As long as I install a virtual CD driver I would like it to support this format as well. But I am hesitating to install Alcohol 120% (which I used in the past) because it appears 32bit-only and comes with a cryptominer (openly) and a DRM of its own nowadays. I also used DaemonTools during the Windows 2000 days but stopped as I read they were first to integrate some shady bullshit in the free version too (now its free version apparently is adware). Another alternative seems to be WinCDEmu but it somehow seems to be 32bit-only too. Installing a 32bit driver on a 64bit system doesn't sound great.
