Racing Green,
Direct X is not an issue with Win98. All games that run on Win98 need Direct X.
You could try:
DirectX 8.1b Runtime for Windows 98 and Me
If you do not want to run:
DirectX 9.0c End-User Runtime
But I would not worry about running Direct X 9.0c since it says:
System Requirements

Take Care,
