Change palette mid-scanline

I've noticed that changing the palette anywhere in the middle of a scanline does not have an effect until the next line. Is this a limitation in the emulator or a hardware limitation?

It's the emulator, which pre-renders entire scanlines with a snapshot of the VERA state - mid-line changes don't take effect on the emulator, but they do on real HW.

Right, that's what I thought. So no beam-racing experiments for me right now ?. Thanks!

If you're interested in beam-racing, you might look into Yazwho's BitMagic emulator.

I'll have a look, thanks. Also trying to find details on VERA's video timings, without much luck so far.

Damn yeah phpBB! That old forum software really SUCKED!

It depends on what you're looking for, but this might help. I think some of it is a bit out of date, but it should give you a good overview.

Additionally I'm sure any questions (or clarifications) you may have would be answered either here or on Discord.
