This product is developed with 8-bit (256 colors) environment with Macromedia Director. For playback performance, it looks much more better with any high color mode (eg. 16-bit -64K colors or more). For any 486-33MHz or lower system with only 8 MB RAM and with windows 3.1 installed, the following change should be made in your autoexec.bat file: C:\DOS\SMARTDRV.EXE /X 2024 256 For any 486 system with windows 95 installed, 16 bits version of QuickTime for windows has to be installed before running our titles. If your system has 32-bit QuickTime for windows already installed, our setup program will automatically re-install the 16-bit QuickTime for windows into your system. For any pentium system with windows 95 installed, our setup program will install the 32-bit QuickTime for windows into your system. Best wishes, hope you enjoy our new DC Super Hero titles.
