Why don’t they instead invest the money to make a pro CRT filter in that device? Games from that era look so much better on CRT TVs

The N64 in particular had the big advancement of hardware-backed anti-aliasing, but also the unfortunate characteristic of forcing it quite strongly on every scene. Games look way less blocky than their PS1 counterparts, but unless you’re emulating on a really high resolution or playing on an actual CRT, primitive antialiasing on such a low resolution can make N64 games look like you’ve covered your TV on Vaseline.

I actually got a CRT just for retro gaming.

Yeah, not much else one can use a CRT for.

I got mine for retro pron viewing. Can’t beat it
