Once you increase your DOSBox cycles beyond your computer's maximum

While the 0.60 release has added support for "protected mode" allowing for more complex and recent programs,
but note that this support is early in development and nowhere near as complete as the support for 386 real\-mode
games (or earlier). Also note that "protected mode" games need substantially more resources and may
