If he was fully committed to the bit, he wouldn't have hidden his SSN from this picture.
There were a few games that worked on the OG gameboy, but were GameBoy color games, the ones that come to mind first are Pokemon Gold and Silver. You could play them on the og gameboy, without color and missing some hardware features, or you could play them on the Gameboy Color as they had intended you do. It was a really nice addition.
I always thought of the GBC as its own generation, since the games were mostly incompatible, just as I thought of the GBA as its own generation for the same reason, but really, it's almost just arbitrary.
There was a bump out, but I don't think it physically stopped you from putting the cartridge into the console, I don't have a GameBoy on me to check right now though. You're right about the missing notch though, but that would only stop you from starting it on the original Gameboy and not the Gameboy Pocket or Super Gameboy. I know for sure I saw the Pokemon Crystal error screen when I tried to play it on the wrong device after being able to play Pokemon Gold on the older hardware.
Maybe I'm the one misremembering?
Oh yeah, I know it.
We could get something like UMDs from the PSP again though. Haha!
It's not really an issue for the games, but an issue with the publishers, I guess, since quite a few 3rd party games have you download basically the whole thing instead of storing it on the cart.
I'm impressed they're sticking with cartridges, since that has been a source of issues with some games. I appreciate it myself. I like them.
This guy is kind of silly for saying that this has been the only time there have been games that fit into the old system, since you could totally put Gameboy Color games into the Gameboy Pocket, they just wouldn't work. They'd scold you and be like "This game can only be played on the GameBoy Color!".
I hope there's no forward compatibility, where games must target the lower spec hardware, since that's the same thing holding the Xbox Series X/S, I hope there's backwards compatibility though, it'd be nice to tuck my old Switch into storage.
I don't think AVGN is a reliable source, it's entertainment. There have been many moments where it's clear (to me) that he's just pretending to be stupid or bad at games just to give the viewer a laugh, so I'd take this one with a grain of salt.
I'm pretty sure this had launched a bit earlier, but yeah, pretty convenient timing.
