Just get Retrotink, it does quite a great job and you can use it with different consoles.
Well, the 2X seems affordable and a good entry point.

Oh it would take a total of 50 games
If I had to make my own list, I'd leave Toshinden off it. That Saturn version was pretty bad compared to the PS1 one. I'd also probably scale back on some of the 2D fighters and try putting more RPGs, SRPGs, 3D shmups and adventure games on it. Maybe something like this (if limited to say 30 games):

-VF2
-Dead or Alive
-Street Fighter Alpha 3
-KOF '97

I'd want a selection highlighting the system's strengths but also spotlighting areas it's perceived as not being great in. There are a lot of really good JRPGs & SRPGs on Saturn, for example, and most people don't know about them. Most people don't think much of the system in terms of first-person games, so why not put arguably the best one (Power Slave) in the collection?
There is no "pressure" that will push Sega to release a Saturn Mini. They've already addressed the reasons why they will not be releasing one.
Modern Sega is not the same company as 90's Sega. They do not care about their legacy. They are not interested in taking risks anymore. I was done waiting for them to re-release their classic Saturn and arcade stuff a long time ago. The full library can be compiled on a hard drive running on Terra Onion-modded Saturn console. Dreamcast is covered too. As for the arcade stuff; all of the games I care about are emulated near-perfectly. Saturn emulation has also advanced too as previously pointed out. The level of attention that Saturn has received from die-hard Sega fans is ridiculous. There are even fan translations of Japan-only games like Symphony of the Night and Bulk Slash available. All of my Sega wishes have pretty much been fulfilled by the online Sega community.
I do not endorse piracy, but people are gonna do what they are gonna do to preserve classic works of art, and that includes video games. If Sega ever get their heads out of their asses, I will gladly drop the cash for official re-releases. Being the collector that I am, I've bought all of their Genesis/ Mega-Drive collections since PS2 days along with their minis. But if they don't want my (nor other Sega fans') money, that's their problem and not mine since all of their classic games are easily accessible.
Well, SEGAGAGA is still without an English translation, as are a few Saturn games like Virus. But outside of that yeah, most of the main ones have been translated and are playable.
Sega recently brought back someone from the Dreamcast era to replace Nagoshi, so that is positive movement. Might be the reason the Jet Set Radio and Crazy Taxi projects have come about. Though WRT their legacy there is a lot more Sega could be doing; hopefully there are sequels to SoR4 and Sonic Mania in the works.
