256x224 D3D fullscreen on CRT issues (1/4 screen visible)

Post by inafking »

Hi, I've been trying to set the resolution of Snes9X to 256x224 at fullscreen to be watched on a CRT TV with the proper native (hardware) scanlines.

The furthest I got was setting the resolution correctly with the mentioned native scanlines with Direct3D and a 256x224 mode but unfortunately, the game is reduced to a quarter of the screen located at the upper-right corner scaled-down.

I've tried messing with the Simple1X filter but to no avail. Switching to OpenGL doesn't solve the issue since there's another issue with that: It doens't change the mode when choosing fullscreen. It just blinks and reverts back to the windowed mode. It only changes the mode when set to a resolution greater than 640x480.

This are my PC specs:

OS: Windows 10 Pro
Gfx card: Radeon HD 5450
Video driver: CRT Emu driver V2.0 (which can be downloaded in this thread and can change the resolutions with ArcadeOSD and input resolutions with VMMaker in the same thread)

The steps to install the resolutions (modelines) as as follows:
  1. Create a text file with this line
    Modeline "256x224@60,0Hz 15,7KHz (60Hz)" 5.408 256 278 303 344 224 243 246 262 -hsync -vsync
  2. Run the VMMaker app and choose Edit Settings -> Video Card tab -> Import modes from file -> Choose the text file you created -> Ok button
  3. Run Snes9x and disable emulate fullscreen, stretch image, bilinear filtering (optionally enable vsync), and choose the fullscreen resolution you created (256x224)
  4. You'll see that hitting Alt+Enter would make Snes9X behave like told above.

    Here are the steps graphically

    I hope you can shed me some light why doesn this happen and a solution for it.
    Thanks in advance!

    Greets!

Sorry if it's late, but I got it working with the latest test build (snes9x_testbuild_29012015.zip)
