I think that there should be a mod that adds consoles IRL that arnt in GDT like coleco vision, atari, GBA etc.
these are the console that i can think of the top of my head
coleco vision
atari sytems Jaugar 20600 etc.
arcade cabinet
GBA
neo geo
sega saturn
maybe nintendo 64 DD and gensis add ons
and can (if someone makes it) make it downloadably through mediafire or adfly (i didnt have a steam accont when i orginaly bought it)
adfly is not accepted on this forum
also
i recommend UME
Also, there are many other mods that have these consoles you listed already 
Cool ideas, some of them are already in use though.
Check out my mod, called The RPT Expansion Pack, it includes 9 platforms, lots of topics and a handful of researches. I will release an huge update next week, adding 9 new platforms and there will be 100 topics in total!
Also, I have some Atari and Jaguar systems in my mod.
Just search for my mod on the forums or on the Steam Workshop. 
the problem is i dont have steam so that kills alot of my options and other might be virus
I’ll put some of these in my mod. It’s right below. It might be a while before they’re implemented.
