GameHack:
http://www.gamehack.com/GameHack is a Windows95 / 98 application that allows you to search for the memory-addresses where your favorite game stores its properties (like money, energy, lives, timers, extras, inventory items or ammo). GameHack gives you access to these found addresses, so you can change or freeze (make it unlimited) the value of these addresses.
GameHack works with all kind of games: you can search in MS DOS-, Windows 3.x- and in Windows95 / 98 games (you just need to be able to start the game in Windows95 / 98).
