Yeah. It's not too hard and not too easy. It also has a lot of supplemental material.

Fire Emblem is on Switch. FFIII is part of the Pixel Remaster series, which is on Switch, PS4, and PC.

Dragon Quest IV is on DS, along with V and VI. Of the three, it's probably the easiest to find. I wish they would port these games to Switch. The first three games are there. DQV is one of the best games in the series. 

Part of the problem with Sonic is that the concept is built around speed, but the actual game design contradicts this. Too many levels penalize you for going fast, and Sonic simply doesn't have the precision of Mario when it comes to platforming. 

Switch allows save states for all of the NSO games. 

One company I recently did business with is eStarland. They sell games, but they also provide repair services. One of those services is replacement of save batteries in NES, SNES, and N64 games, and it's pretty cheap.

They have a small store in Lawton OK called Game King. Mostly I shop at Vintage Stock and Game X Change.

I remember Mansion of Hidden Souls being described as Sega's version of The 7th Guest, which is one of the two games (along with Myst) that launched CD-ROMs as a viable storage media. My parents were playing The 7th Guest when these games came out. 

Warsong was a US version of Langrisser. I have the Langrisser I & II compilation released by NISA on Switch. It has an option to switch between thw original Genesis artwork and a more modern style. 

I remember the Night Trap controversy. I never played the game. I also remember that it starred Dana Plato, the actress from Diff'rent Strokes. I think it's on modern consoles now.

As far as games on a Genesis Mini 3, which hopefully wouldn't look like the cheap Genesis 3 units made by Majesco,I think all the really good Genesis games are on consoles now. The only games I am really interested in are Lunar 1 and 2, Vay, and Popful Mail. All of these were Working Designs localizations, which apparently means that the rights to these games are pretty messy. That's a pity, too. Lunar 1 and 2 were awesome. Not only were they the best Sega had to offer in RPGs, but they were as good as Square's SNES games. Popful Mail was made by Falcom.  Other than that, I guess I wouldn't mind seeing the Genesis versions of the Mortal Kombat games. They weren't great, and the second and third games were better on SNES (the first game was a complete disaster on SNES beyond the censorship), but the first game actually had a catchu soundtrack that took advantage of the Yamaha FM Synthesizer the Genesis has on board.  

SMB 3 is one of the best Mario games ever. I played it at McDonald's for a promo/competition Nintendo held in 1989 before its actual commercial release. I'm pretty sure it was a tie-in with The Wizard. McDonald's was also giving away those Mario Happy Meal toys with the suction cup-spring Mario and Luigi riding a little cloud car. I have the Mario one. I also saw SMB 3 in one of those PlayChoice-10 arcade machines Nintendo used to make, also the year before the official release.

It's on Switch as a downloadable title, as Sega Ages: Herzog Zwei. 

Ukraine's Ministry of Foreign Affairs started a campaign in 2018 to persuade English-speaking media to refer to the city as Kyiv, the traditional Ukrainian pronunciation, as a opposed to Kiev, as the latter was a Russian-language pronunciation held over from the USSR. The US government fully committed to using the name Kyiv in 2019.

Turkey officially changed its name in the UN to Türkiye. For the time being, they accept the spelling of Turkey from foreign media, but I foresee a time not too far in the future where Türkiye will be adopted by Western media and politicians. It's still listed under its traditional English spelling in Wikipedia.
