Thanks, you and Laurent have made my day! I definitely can. Probably on the weekend.
Is it possible for me to run a true 4:3 version without the side borders? I'm using a workaround of a weird screen mode but I can't fill the monitor this way.
I also tried editing the embed page..
<div data-height="448" class="game_frame game_loaded" style="width: 796px; height: 448px" data-width="796"> <button title="Enter fullscreen" class="fullscreen_btn">
..to a width of 640 (and also tried 320x224) but it didn't make a difference.
Oddly if I run it at a screen resolution of 640x480i then correct centering kicks in, but then I have interlacing and soft scaling. It doesn't look anywhere near as nice as it does in 224p.
I don't know if I'm doing a very good job of explaining this. 🤔
