Congrats!! it's been a while since I first exchanged my STEEM for fiat to buy something. It's amazing experience!!
I like playing retro too... Though I like the SNES-styled recent indie games more (the best combination of the old and new)...
I found some old skool Joystick like I had in my childhood..
Didn't know that these adapters existed... How old do you think the joystick is?
with this adapter you can connect all old joysticks.. I think it is from 1985 or so
