[Àû¿ë´ë»ó: 0.74_SVN_new, DOSBox-x]

Whether or not to emulate a Sierra or compatible RAMDAC at port 3C6h-3C9h.

Some DOS games expect to access port 3C6h to enable highcolor/truecolor SVGA modes on older chipsets.

Disable if you wish to emulate SVGA hardware that lacks a RAMDAC or (depending on the chipset) does not emulate a RAMDAC that is accessible through port 3C6h.

This option has no effect for non-VGA video hardware.
