To begin, launch xemu and load your game of choice. Once you’re at a screen where a numerical value is visible—like your health, gold, or ammo—alt-tab and open Cheat Engine. Click the computer icon to open the process list and select xemu.exe.

But history is rarely experienced "as it was." It is viewed through the lens of the present.

Suddenly, a game that was once a frustrating slog becomes a museum exhibit we can walk through at our own pace. We can give ourselves infinite ammo in Halo: Combat Evolved not to break the game, but to feel the power of the Assault Rifle without the anxiety of reload timers. We become tourists in our own nostalgia, unburdened by the punishing mechanics of yesteryear.

Now when you scan for 100 (health), Cheat Engine will only look inside the virtual Xbox’s memory.
