Interlace is tbh not the A1's strong suit, it just line doubles the input - so depending a bit on the source, it will look wobbly. My XRGB2 combines the fields and displays the resulting 480 frame very nicely, but you need a framebuffer to do that.fernan1234 wrote:I'd really like to check out one of these scalers. I know it was designed primarily for arcade boards, but it lists support for 480i/576i, so I'm wondering how interlaced 15khz looks like scan converted to the 31khz output. Does it look like the well-regarded de-interlaced output of the Micomsoft scalers, or maybe even better? And are in-game resolution changes (especially 480i<-->240p) handled without sync drops by this scaler?
240p test suite on dreamcast looks good though.
As the line-count changes when it switches from 480i to 240p, it will resync. I haven't tested it with instruments - but with a CRT and the 240p test suite, it's about 1 second - you can see it in the video I posted a while back, https://youtu.be/MUx4QuohGdg?t=179
