Not sure why people always say it's so hard to build GraalVM ... all you need is roughly 2 prerequisites and one build command. The prerequisites are a "Labs JDK" which is essentially a slightly modified OpenJDK with more up

I think there is some confusion about "ubershaders" in the context of emulators in particular. Old Nintendo consoles like the N64 or the GameCube/Wii didn't have programmable shaders. Instead, it was a mostly fixed-funct

The only problem with real VTs is you have to be careful not to get one where the CRT has severe burn-in, like in the ebay listing. Sure, some VTs (like the VT240 or VT525) are a separate main box + CRT, but then you're missing the &qu

Simple: a real 3.5" floppy disk drive has moving parts and various things that age and eventually break. For example I have an old device with a broken floppy disk drive which can't even read a real floppy anymore. With the metal

You are indeed right. I'm not sure how to efficiently implement a median here though, because a single frame is around 120MB large already. I assume I could/should compute the median over only a few frames to limit memory consumpt

This project looks interesting. I saw you use stty to configure the console, but there is a native "UNIX way" to do this via tcgetattr/tcsetattr, you'll have to figure out how to use these C functions elegantly in Go tho

For the record, you could also use a much cheaper MCU like e.g. an STM32F030C6 which costs around $0.60 for a single chip and around $0.45 for 30 chips at LCSC the moment. Of course this is completely irrelevant if you build a small number
