Having a PS2 used to make my PS1 irrelevant, until I started running my PS2 through component and discovered my TV can't handle the 240p signal of PS1 games through component.
I know I wasn't the only one to this, but: When I was a kid, I used to plug the Gameboy Camera into the Gameboy Player, run the SNES into my VCR and record myself (with no audio).
