    Son wants SNES, but that doesn't seem to work at all.
    Think clock freq is too high for the SWaP module... At least, this particular one...

    @Wuerfel_21 Did you try any of the other emulators with your Stamp? Or, was it just Megayume?

    Miso didn't exist back then, we only had Mega and Neo. So that wasn't tested at the time and I don't think I've bothered since. What kind of "doesn't work" symptom are you getting?

    blank screen...

  • Black or white?
    Immediately (menu) or after ROM load?

    White screen on menu -> bad config or failed to boot (bad power? -> try burn-in RAM test)
    Black screen on menu -> shouldn't happen, crashed somewhere
    Black screen after ROM load -> bad config
    White screen after ROM load -> shouldn't happen, crashed out super hard

    Put it in the freezer for a while and now it works...

    Well, lasted about 15 seconds...

    Guess one could boost the SWaP module Vdd supply from 1.8 to 2.0 V and see if that helps.
    Or, maybe adding a fan...

    But, not liking the odds...
    Think he's going to have to learn to love Genesis...

    On the other hand, do like how can get 100 resistors to give 2.0V on Vdd for 41 cents...
    Might be worth a shot...

    I'd be doing modes with much more blanking, but it should be able to handle that. Might configure for /12 pixel clock divider and then adjust the H timings on that basis.

    Tried a couple of quick tests with changing the config file's HDMI pixelclock to both 24.2MHz with 768 total pixels/line and then 25.2MHz with 800 total pixels/line (standard VGA timing @60Hz), but the LCD didn't seem to work with either. I think I had the format correct. Will have to test out in more detail with the P2 attached so I can vary things finely and see what range of values will work and how fussy this LCD really is.
