I am planning a DOS/Windows 98SE build. Okay so i could use compatibility patches or DOS Box/virtual machine but i am interested for the fun of doing a build and also the true experience. I've got a bunch of old games like Sonic CD PC, Command and Conquer, X Wing vs Tie Fighter, Quake II ect that i am interested in playing again (yes i can stomach ye old graphics if the gameplay is good). The choice of Windows 98SE is because it has MS-DOS 7, plug and play, compatibility with Windows 95 software, larger ram and storage compatibility than 95, overall to me is better. I heard some old DOS games do not like certain CPU speeds, literally they run too fast on more powerful cpu. There is the possibility i could get an i486 system later or use slowdown programs. I need at least a Pentium to run Sonic CD, i reckon some of the later 90s games would be too slow on an i486 anyway. Windows 98 requires a floating point unit to run so id need at least a Pentium MMX. Ive listed the hardware ive settled on.
