1. There is bad link for Hoyle Casino 2000. As it's obvious by checking readme on disc, it's Hoyle Casino '99. And entry for '99 on site is missing altogether.
2. There is different Hoyle Casino '99 disc on Archive.org too. Seems, it's earlier version. It have Win95/3.1 installer, while disk above is Win95, but Win32s compatible.
3. True Hoyle Casino 2000 seems is this disc. It named "Hoyle Casino 4" inside, it's Win95 only, and it's definitely different from supposed 2000 disc on site.
