Oh my god, this is the anti-nostalgia I'd totally forgotten about. Brossentia's streaming FF5 in ZSNES for DOS, one of the old versions where sound is still totally fucked. This rules.
pay close attention to the shadow rendering on all the UI elements (menus, mouse cursor, dialogs):
every element in the UI has a depth and the shadows fall on each thing in the stack appropriate to how deep they are in the screen!
this is all in tightly-optimized handwritten x86 ASM pixel drawing code running on DOS-era hardware from the 90s, just to add a detail that makes the interface subconsciously more pleasant and intuitive but won't be noticed by 99%+ of people.
your brain usually processes and filters out shadows automatically for you unless you're really paying attention to what you're looking at.
there's so much about how we as living creatures intuit and understand what we're looking at just sitting there in our brains.
the concept of "3D" user-interface elements (even the buttons and such in Windows 9x that have light/dark borders on the upper-right/lower-left to give the illusion of being slightly raised count in this) seems to be largely falling out of favor; despite the fact that we all have powerful GPUs in devices of all sizes, they're all wasted on a design landscape that's a flat, solid-color, sea of low-contrast nothing.
(but yeah, nobody should use zsnes for emulation in current year, btw - not only is it horrendously inaccurate, there's also a VM escape vulnerability kicking around in it. but it's got some lovely stuff in its GUI!)
