I currently own these:
New Nintendo 2DS XL (modded)
Nintendo DSi (modded)
Wii U (deluxe, modded)
Dreamcast (with a GDEMU and a 2nd hand power board)
Genesis Mini
PS3 Slim

I haven't really modded these last two yet bc I havent felt the need yet (there's easier ways for me to play other genesis games and I'm still going through the PS3 games i currently own)
For my next console i'm thinking of getting a Saturn or a PSP/PS Vita since they both have lots of games i'd love to check out. I'd love to get a more modern console too like a Switch or a Series S, but it's hard to justify with games being so expensive over here >_>
