I haven't been there in some time, but I used to have Burger King as my go-to when I was out shopping and got hungry. I always much preferred it to McDonald's, though I do fondly remember as a kid I used to really like going to the latter because of those Happy Meal's, where I'd spend all the time playing with the silly toy instead of eating my food.
I believe it was the opposite for me also. While I did have an NES clone as a kid and used to play that a lot, I never had the SNES as a kid, and instead, had the Mega Drive. I used to love playing Sonic 2 on it back then, but ofc I used to really like going to my uncle's and playing Super Mario World. Eventually my aunt ended up with their SNES, and I very much recall playing Donkey Kong Country, Super Mario All-Stars, and Super Mario World. I even recall playing games like Theme Park on it, and enjoying it a lot. It's only when I became a teen that I actually got a SNES myself.
Anyway, this one is tough. I never had a Framemeister, and always got put off by the high price. While it's something I'd love for compatibility reasons, I'm more familiar with the OSSC. The RetroTINK is something I was looking at for the N64 and NES, though only a basic version of it really for composite and s-video. Given the low input lag though, I'm inclined to go with OSSC, at least in terms of using RGB signals. I know that there are compatibility issues, but my TV plays ball with it no problem, and given the OSSC Pro does have extra features and a frame-buffer, I would probably choose this. As of now though, my OSSC is doing the job, so I'll avoid buying the Pro for now.
Did you prefer the Game Boy Advance, the Game Boy Advance SP, or the Game Boy Micro?
