Technical Q&A AMTPE08
Bit Depths and Device Drivers under Windows


The Apple Media Tool and Apple Media Tool Programming Environment products have been discontinued. For more information check out: AMT/PE Discontinued.

Q: Can our 256-color AMT title work on a Windows machine with 65,000 colors? When we try to run it, we get the error message:

"This machine doesn't support 256 colors."

A: Unfortunately, applications created with AMT insist on a 256-color video driver, and Windows does not allow applications to change video drivers on the fly. So if your title is already pressed and running off a CD, you need to manually load a 256-color video driver before running your title. Go into Windows Setup (in the Main program group), choose Change system settings from the Options menu, and pick a display driver that supports 256 colors. Restart Windows for the new driver to be loaded.

If you are using the AMT/Programming Environment and Microsoft Visual C and don't mind rebuilding your project one more time, you can also use a modified version of APPLICA_.C that eases the 256-color requirement to 256 or more colors. Send email to Kate Adams (kate.adams@applelink.apple.com) to get a copy of this file.

Note: A future version of AMT and AMT/PE will address this restriction.
