Single CPU Loader is a portable freeware app that allows you to play older games that won't work correctly on multi-core processors.

Single CPU Loader is as simple to use as you would hope. Click on Start program and browse to the executable with File Explorer.

If you play your games using command-line switches, you can enter them in the bottom box and then start your app. Change your mind or make a mistake with your switches, and you click on Clear path to start over.

Single CPU Loader is so simple to use; we only needed one screenshot for our review, which you can see below. Single CPU Loader should be in any retro gamers collection.
