NOTE THE DEFAULT SETTINGS OF MAME WILL NOT GIVE GOOD RESULTS. YOU NEED TO DO THIS STEP:
You will need to check/edit the MAME.INI file, which should reside in the Mame folder. If this file does not exist, you will need to run from the command-line:
MAME -CREATECONFIG
After the INI file is created, open with Notepad and set: Hardware Stretch OFF. In general, other settings can be left at the defaults.
Windows XP, 2000 and 98.
Install the card into the AGP slot. The card must be installed and connected to an arcade monitor to install the drivers.
If your PC has previously had any ATI card installed, you will need to remove the existing ATI drivers. Do this by downloading and running this utility:
Start (or restart) Windows. The Windows screen should be displayed at 640 X 480 interlaced, 16 colours. To use the ArcadeVGA built-in modes the ATI driver needs installing. Insert the Ultimarc CD. Run the driver Setup program in the correct folder (98 or XP or 2K). Reboot as prompted. Windows may ask if you want to replace newer files with old. You MUST choose to replace all the files. After re-boot, install the ATI control panel by running Setup in the "Cpanel" folder on the CD.
Right-click on the desktop, select "properties" and set the colour depth to "32 bit colour".
Blue Screens in XP/2000 Windows XP may try to invoke the built-in Microsoft ATI driver and this will not work with the ArcadeVGA card, and causes a blue-screen error. If you see this, re-start and hold down "F8" and choose to start in Safe Mode, then install the ATI driver from the ArcadeVGA CD. To do this, you will need to enter device manager, right click on the expanded video card listing under 'Display Adapters' (or, the undesignated option, if the device has not been recognized at all, and has a yellow X next to it), click on properties, go to driver tab, and click on 'update driver'. This is the only way to install the driver in safe mode, as attempting to install via ATI's setup utility will produce error messages and result in a failure to install the driver. You will need to point the driver install to the correct location on the CD as mentioned in "Forcing a driver install", further down this page.
