I play O2Jam on the V3 server. This game has not been updated in over 10 years, the developer has been bankrupt sine 2009, and there is no way this program will be modernized for Windows 10. This uses old DirectX and Direct Draw features that have been unsupported since Windows 8.
How can I force Windows 10 to run Direct Draw versions from 11 years ago in order to make this game even start correctly? It is unplayable on Windows 10 with the current graphics libraries.
