The question probably speaks for itself. I know that they're Windows-based games, so inherently a copy of Windows must be available. That precludes using DOSBox, but would any of the following solutions (or others) work?
- Boot Camp with Windows 7?
- VMWare with a Windows version of the appropriate vintage?
- WINE? (Is WINE even available for Mac?)
- Profit! (Oh, wait ... Um ... Fill in #4 for me?)
Details of the machine in question: MacBook 13", integrated 256M graphics, 4GB of RAM, 2GHz Intel Core Duo.
