VGA blues :(

[Dr.FrankenCast]

i got them vga blues, sure vga give out a whoping thrust to
the sound and truly amazing graphics that a DC can truly
pump, but not all games are VGA compatible, so whenever i
pop in a disc and that non vga compatible screen pops up, i
cant play the game, is there anyway to bypass this and
still play on your PC monitor?

1. Switch off the Dreamcast and monitor, and set the VGA box switch
to the TV position. Turn the volume down on your speakers, to
allow you to hear the Dreamcast's drive spinning.
2. Put in the game disk and turn on the Dreamcast.
3. Listen to the drive. You will hear it start spinning at slow speed
to check the disk. After a couple of seconds you will hear the
drive speed up. At this point, flip the VGA box switch to the
VGA position.
4. Wait about 10 secs as the game continues to load. Turn the monitor
back on, and hopefully the game will now be running in VGA mode.

You can leave your monitor on the whole time if you like. It's
just that some older VGA monitors go haywire whilst the VGA box
is in TV position, because there is no VGA signal present. Most
newish digital monitors will quietly go into a standby mode when
there's no VGA signal present, in which case you can just leave
it on the whole time.

This trick has been found to be successful on SOME non VGA compatible
games, but not all. Therefore there is no guarantee that this trick
will work with the game you're trying.
