    I’m just curious, why is GPSP configured as a stand-alone emulator and not a core in RetroArch? I was hoping to configure a shader and overlay for my GBA games…

    because it wasn’t available as a libretro core until recently and hasn’t yet been included.

    It always been available it just that theperformance with the core is terrible compared to the standalone GPSP binary

    Yeah I’ve come to the conclusion that there’s just too many compromises using software shaders on the Pi, I’m going to try a inline scanline generator and see how that does.

    Which scanline generator will you try?

    I’ll be honest even though I’m gonna look like a nut here… I couldn’t decide, so I ordered two πŸ™‚

    T-SLG v1.6 from http://godlikecontrols.com/
    and this one http://www.beharbros.com/#!slr/c4j4

    other choices I found in my research:

    My setup is probably a bit obscure – I’m going from Pi B+ to an HDMI to VGA adaper to a scanline generator to a 19 inch CRT computer monitor in my arcade cabinet.

    Would they work like:

    Pi – HDMI to VGA – Scanline Gen – VGA to HDMI – HD TV

    or is that crazy?
    Or maybe I should just use the VGA in that many TVs have?

    I do have an XRGB mini but cant really bung that in with each Pi setup I do.

    That might work but it does seem kind of crazy huh?

    From my quick research, this XRGB-Mini is the way to go if your source and display are HDMI and you want to add scanlines. I don’t have one myself, so you tell me πŸ™‚ Have you tried it? Does it work well?

    Well its pretty good as well as including a lot of options to tweak the output just as I want it, but I tend to use it with my RGB megadrive rather than a Pi.

    I’ve just ordered an SLG3000 to try out and see if thats good to use with the Pi.

    Thinking about it, how does the sound get carried through the HDMI to VGA cable?

    You should do a video showing how it looks to enable scanlines on the Pi at different resolutions using the XRGB-Mini πŸ™‚

    Thinking about it, how does the sound get carried through the HDMI to VGA cable?

    HDMI carries video and audio. If you look at the adapter I bought, it has an audio jack. So it’s really an “HDMI to VGA/audio adapter”.

    If you use this adapter, make sure you feed it separate power (via the micro USB port on the adapter). From what I understand you can damage the Pi trying to pull the 5VDC from the Pi’s HDMI port.
