Did any of the Metagaming Concepts’ games make it to the PC

Modern CPUs usually change their clock speed based on CPU load in the default setting. You might be able to use the Power item in the Windows Control Panel to switch the power scheme from the default Balanced scheme to Energy Saver. That should lock your CPU to its lowest clock speed.

You can use something like CPU-Z to monitor the clock speed to see if your CPU actually clockspeed changes when you change the powerscheme.

I have actually used this technique to play Commandos. Normally my CPU would switch into performance mode (all 4 cores at 3.2GHz) and the game would run too fast, making it hard to play. After setting the Windows Powerscheme to Energy Saver (all 4 cores on 800Mhz - 1 quarter of full speed) the game would run at the correct speed.

Edit: About using a Virtual Machine:

Virtualbox has the ability to limit the virtual CPU to a percentage of the host CPU, see CPU execution cap in the Processor Settings section. The manual does note that limiting the CPU this way may induce timing problems in the guest, which isn't what you want for older games obviously. Another problem with virtual machines is that hardware acceleration for graphics is still not very well supported, so that limits the usage of VMs for games quite a bit.

I have tried this with Commandos for instance, but the result was not playable. That's when I switched to the technique above to limit the speed of my CPU via Windows Powerscheme.

Old games that are in excellent condition can potentially be worth a lot of money, so it is not surprising that you have found Archon I sell for a lot of money on eBay. If you are adamant about obtaining this game, you need to research how much the game has been selling for over the last year or two and be prepared to pay approximately the same amount for the game. It will require patience and self restraint, but you should eventually be able to purchase that game you so desire.

Racketboy.com is my favorite community driven retro games website out there. They have some great guides to help you get informed on the best way to proceed with retro game purchases:

• How To Find The Best Gaming Deals on eBay
• Comparing Massive Markups For Pristine Retro Games
• Learn How Much Your Video Games Are Worth

They also have a thriving forum with several members that are avid retro gamers and game collectors (some of them even own video game stores), and many of them have channels that they can call upon to find rare games for a fair price.
