There is minor willy demo program about that runs on a 48K and relies on analog effects to display different brightness on the screen -- this sort of thing is not going to display properly on the Next.
That sounds interesting to try on old hardware, which demo is that?

Maybe this is a demo of Walking Manic Miner

Well, you can also check the correct four squares on old equipment

Not yet. It's on the list of things to look at when the CPU is revisited, along with MEMPTR and SCF/CCF. That'll happen after a few other things get finished. The fixes already done in the MISTer can't just be copied verbatim because they don't deal with the expansion bus or hardware signals for attached devices. So it'll need some extra work too.

We mentioned this a couple of times before, here are all the programs that demonstrate this ULA effects:

Apart from the real hardware, currently only the ZX Spin emulator can display all these examples correctly.
Unfortunately, SpecEmu with newer versions (from the last year and a half) does not display the "stripes" demo correctly.
I hope Woody corrects this in future versions.
