PS2 for sure. So many great games that made my childhood and its easy to mod and repair.
SNES is close second. Was lucky enough that I got one growing up (it was 10 year old console at that point) and the 16 bit graphics and the music always take me back.
Nooo… that was my goto rom archive after emuparadise went down. F u Nintendo I‘m not paying a monthly subscription to play retro games.
