I want to run a game compatible with Windows 95.
Literal
Windows 95 [compatible-対応] [genitive-の] game [object-を] run [want-たい] [explanatory-のです].
対応 ('compatible with, supporting') is a common tech word. Used as [system]対応 without particle = 'compatible with [system],' 'supporting [system].' の connects 対応 to ゲーム ('game'). The transitive verb 動かす ('to move, run, operate') is the causative pair of 動く ('to move' intrans.), used here in its tech meaning 'to run/execute (software).'
