I see this.
My assumption is its some kind of html/js cache, local storage across browser sessions maybe. And when you click an email it realizes it needs to update.
The display also supports partial updates, so you can just upload a few sub rectangles of what has changed onscreen. AKA "dirty rectangles".
You can get over 60fps depending on how much is changing, and since these games are on a static background, that's not much.
I agree with what you are saying, except that "I AM ERROR" isn't actually a bug. The character is intentionally named that in Zelda II, even in the original Japanese.
Ambernics seem to be very high build quality. I got the RG280v myself after some research. It's not as powerful (so it can't play every PS1 game at full frame rate) and does not have analog sticks.
But it is very small and I think that along with save states and standby helps it be more of a pick up and play toy for short bursts, more so than my 3DS or vita.
Or what actually happened was the radio show asked if white going first was racially based, concluding that it was not. But conservative media spent days getting themselves outraged over it before it even aired.
Mino Games is YC backed, as their job ads pop up on here occasionally. Interestingly they seem to have shut down their older larger scale Mino Monsters games and are focusing on (what i assume to be) smaller scale collecting games.
I remember some launch demos were able to exit, usually with a forced splash screen ad for the full game. I thought it was a neat trick to use the xbox button to quit out of those and skip the ad.
So maybe exiting was allowed early on and discontinued later.
When folding it pretty much behaves like a normal notebook, where the screen folds onto the keyboard, only that there's more screen under the keyboard.
