# Overview of Encryption Requirements

When you submit a title for encryption, 3DO CD Operations checks that all requirements are met before starting the encryption process. This document summarizes the requirements, providing references to more detailed information as appropriate.

Warning: 3DO CD Operations will not encrypt titles that don't meet the requirements outlined here.

## Minimum memory testing

3DO Quality Assurance tests each title in both in the minimum memory environment, and in the nonrestricted full-memory environment. Each title is briefly tested before encryption, then for seven days after encryption.

You can run the minmem utility in one of two ways:

- Type `minmem` at the Debugger prompt after running the boot script but before launching your application.

- Include `minmem` in the AppStartup script.

See Testing Your Title in the Minimum Memory Configuration for more information.

## Low memory access

Your title must be low memory clean. See Checking for Low Memory Pointers for more information.

## Three-Second 3DO licensed product symbol

Each application is required to display the 3DO licensed product symbol, in at least quarter-screen height, for a minimum of three seconds when the title boots up.

Use the files containing the 3DO licensed product symbol which are included on the installation CD-ROM at top level in the "Approved 3DO Logo Art" folder.

The three-second 3DO licensed product symbol is not required if the title uses a banner screen (see Preparing and Using a Banner Screen).

## CD packaging and artwork

CD artwork and CD packaging artwork are inspected for adherence to 3DO guidelines. Artwork within the application is not censored in any way; only the CD surface and CD packaging artwork must conform to certain guidelines.

The approval process is described in the Essentials Kit.

Files you have to deliver

3DO Developer Services needs to see the /takeme directory of your title to verify that you created your cdrom.image file with the appropriate 3DO system files.

When you submit your title for encryption, include

- the cdrom.image file

- the /takeme directory (without executable and data files).

Deliver these files in HFS format on CD-ROM. Send at least two copies. See the Disc Processing Form for detail; a copy of that form is required for encryption.
