Hello all. This is my first post on this board.
I am trying to set up Fullscreen atari 2600 emulation on my 50" Panasonic DLP HDTV for my wife as a Christmas present.
I have a computer running Windows XP Pro with a GeForce Ti4600 graphics card that connects to the TV via a VGA port. Using the TV's VGA port, I can only display 1024x768 at 60Hz. The TV is very particular that the video signal be formatted as such, otherwise all it displays is a black screen. The display is in standard non-widescreen format with vertical bars on either side of the computer display.
Here is the problem: I can't get an emulator to work that will properly display in fullscreen mode on the TV.
I have tried the latest binaries of Stella and z26 (as of 12/2005) and each emulator has its own problem.
Stella (using StellaX) displays a beautiful fullscreen picture in OpenGL mode as long as the "Maximize OpenGL FS" option is selected. Problem is that with certain games, the refresh rate of the TV isn't synced with the refresh rate of the game. Because of this, certain sprites that share processing time with other sprites become invisible. For example, on Space Invaders I can not see both my own shots and the aliens' shots at the same time. Sometimes I only see my shots, and sometimes I only see theirs.
On z26, I was able to fix this by tweaking the phosphorescence effect. The problem with z26 is, I can't get the fullscren mode to work on my TV. My screen goes black as if receiving a signal out of its expected range. Stella does the same thing without the "Maximize OpenGL FS" option.
I have read all documentation on both emulators and tried all video modes and settings, but I can't fix either problem on either emulator. If I could get just one emulator working in fullscreen mode with the correct refresh rate, I would be happy.
If someone could help me set this up before Christmas, I would really appreciate it!
One more thing. I need whichever emulator I use to work with the Stelladapter. That's why I've only tried those two emulators so far.
