Can a PS2 play all PS1 games?

I'm asking this because, I remember when the PS2 first came out a lot of people complained about how it couldn't play some games and that the data of old games couldn't save onto PS2 memory cards.

I have no problem playing PSX games on the PS2. Although you do need a PSX memory card in order to save your progress.

I bought my PS2 right after it came out and I wasn't too happy with the launch titles so I basically played PS1 games for a while, they all should work fine, just need a memory card.

Depends on which version it is. The original "fatty" PS2's actually have the ps1 chip in hardware... it's just that when a ps2 game is loaded, the ps1 chip is then used as an I/O controller... and in some versions of Sony's SDK, it could optionally be used (if the dev was sure they weren't going to be using any of its USB/firewire ports) to be a secondary co-processor to offload tasks to. When a PS1 game is loaded though, the boot loader transfers control from the EE to this chip, and uses the GS component to replace the PS1's GPU. On the newer, slimline PStwo's, this ps1 chip and its RAM are removed, and a software emulator is used for PS1 games. Further, the EE/GS are overclocked to compensate for the inefficiencies of the emulator. So this BC is imperfect, and could also cause problems for those ps2 games that used that chip as well.

Mostly. But there are a handful that can't play on the PS2. I know Mortal Kombat Trilogy has problems on the PS2.

I have a "Fat" Ps2 since 2003, and I usually never put ps1 games on it. Some games freeze (Star Ocean 2, Grandia, Silent Bomber), and sometimes they won't simply load, and I think this is not because of the console's hardware, but because of how the Ps2 tray was designed. When I place the cds on the tray and hit the eject button to close it, sometimes the Ps2 will make a strange sound (sounds like the cd can't spin and the console is having trouble reading it). When I hear it, I know that the game will not work, and more importantly, there's a risk of the Cd being scratched and tus ruining it. Bear in mind that I have a Pal Ps2, Idk about Ntsc/ u Ps2's. 

Still, if I were you, I would buy a Ps1 console, they're dirt cheap these days.

Your PS2 is dying. That was the first sign of my fattie being on the way out. Next it'll start rejecting PS2 games.

Considering it's been doing that for 10 years now, I'd say it's pretty much alive. It plays all Ps2 games, even the Cd-rom ones, with no problem or sound whatsoever.
