CRT Emudriver is a patched version of Catalyst 6.5/9.3/13.1 ATI Drivers, for ATI Radeon cards and Windows XP 32/64-bit and Windows 7-64-bit operating systems. Its purpose is to improve some features related to low resolution video modes and their use in emulation on CRT screens, TV and arcade monitors.

These drivers will allow you to obtain the best of GroovyMAME and other emulators. They come with a table of pre-installed video modes that GroovyMAME expects to find and use. After installing, you can use VMMaker to better adjust the mode list in order to fit your particular monitor type.

CRT Emudriver's main features as compared to regular drivers are:

  - Support for dynamic modeline reprogramming without the need to restart the system.

  - The number of video modes supported is double that of regular Catalyst drivers, which are limited to 60 custom video modes you can define and have available simultaneously. The total number of  modelines supported by each driver version is:

      - CRT Emudriver, based on Catalyst 6.5 XP-32:      200 modes
      - CRT Emudriver, based on Catalyst 6.5 XP-64:      120 modes
      - CRT Emudriver, based on Catalyst 9.3 XP-32/64: 120 modes
      - CRT Emudriver, based on Catalyst 13.1 W7-64:    120 modes

  - Fixed support for real 320x and 400x resolutions, that with regular Catalyst drivers are hardcoded as doublescanned modes.

There are several versions of CRT Emudriver. You must select the one that fits your operating system and video card:

Older cards are supported by the version based on Catalyst 6.5. Newer cards are supported by the one based on Catalyst 9.3. Some cards are supported by both 6.5 and 9.3 versions, in this case it's recommended to use the 9.3.

Video cards marked in red are supported, but they don't support low pixel clocks. For these cards, you will need to use the DotClockMin = 8.0 option in vmmaker.ini in order to scale low resolutions horizontally.

After restart, you will need to manually select one of the 15 kHz modes from Arcade OSD.

When installing CRT Emudriver in Windows 7, some extra caution must be taken:

1.- Run the Setup program with ADMIN RIGHTS enabled.
2.- DO NOT restart the system when W7 prompts you to do so, let the Setup program finish, allow it to set TEST mode on.
3.- CRT Emudriver for W7 doesn't boot in 15 kHz automatically after restart. You need to manually enable a 15 kHz mode from Arcade OSD.
4.- Remind to always run VMMaker with ADMIN RIGHTS.
5.- Windows 7 does not support "magic" resolutions. Use "super" resolutions instead.
