KB122490 - Macintosh The Ultimate Haunted House

MORE INFORMATION

Here are some general guidelines to follow when configuring your machine:

Run only one application at a time. If other applications are running, close them before restarting The Ultimate Haunted House.
Check the amount of memory being used by your system software. To do this, return to the Finder, select the Apple menu at top left of the menu bar, and choose the first menu item, About This Macintosh. The Largest Unused Block needs to be greater than 5120K to run The Ultimate Haunted House. If System Software is the only item listed in the About This Macintosh dialog box, and your Largest Unused Block is less than 5120K, you need to reduce the amount of memory consumed by your system software.

You should refer to your Macintosh documentation to perform the above procedure. However, here are some suggestions to follow:

Open the Memory Control panel and check the Disk Cache setting. For best performance with The Ultimate Haunted House, set the cache to 32K.
Large numbers of fonts and sounds consume system memory. Removing those you aren't using will make more memory available.
Third-party system extensions such as screen savers, fax software, desktop pictures, menu-modifying utilities, and other system enhancements increase the amount of memory consumed by your system. Removing some or all of these extensions will increase the amount of memory available to applications. Be sure that you save anything you remove from your System folder in a separate folder on your disk so that you can restore it later.

If you receive a memory error while running Byron Preiss Catalog, first try setting your monitor to 256 colors using the Monitors Control panel.
