LOL you can't play Warhawk. Only remote play enabled games- all PSOne classics, I believe WipEout HD, Pixeljunk Monsters and Blazblue, among others. You can play Lair, but you can't really progress because Sixaxis is required. Bionic Commando Rearmed, Pixeljunk Eden... here's a full list, courtesy Wikipedia:

• Aqua Vita/Aquatopia (PSN game)
• Bejeweled 2 (PSN game)
• Bionic Commando Rearmed (PSN game/demo)
• BlazBlue: Calamity Trigger (BD game)
• High Stakes on the Vegas Strip: Poker Edition (PSN game)
• Imabikisou (BD game/PSN demo)
• Lair (BD game)
• LEGO Batman (BD game)
• Life with PlayStation (PSN software)
• Mainichi Issho (PSN game)
• Misato Katsuragi's Reporting Plan (PSN game)
• PixelJunk Eden (PSN game/demo)
• PixelJunk Monsters (PSN game/demo)
• PlayStation 1 games (CD games/demos, PSN games/demos)
• PlayTV (BD software/PSN demo)
• SingStar (BD game)
• SingStar Vol. 2 (BD game)
• SingStar ABBA (BD game)
• VidZone (PSN software)
• Zuma (PSN demo)

I can confirm that WipEout HD does not support Remote Play, and that the first boss on Crash Bandicoot is really annoying >_

LMFAO WOW

I just turned on and off then back on my PS3 from the internet... No SHIT..

I looking at my wedding photo's, just played some Pixel Junk, man would be kick ass if Fat Princess, Warhawk, or Pain worked..

Going to throw a PS1 game in, in a few min to see if that works.

The Aquarium game doesn't work because I need a camera.

This is kick ass, No idea when it siad Internet when I first set this remote play up years ago that it meant anywhere..

I thought for some strange reason I had to use my own home router...

Thats why I always picked Playstation 3 network..

hahahahahahahaha..

I feel like it's X-mas..

I put my old 60 gig hard drive back into my PS3 a few days ago because the 120gig broke, so now i'm downloading and installing Warhawk Patches and DLC...

This is freakin sick..

Found this thread:

Big thanks to StalkingSilence for keeping his thread updated for so long.  I will try to carry on what he started and keep this thread as updated as possible.

* Only the demo was tested, not the full game.  Someone please test the full game.

I hear alot of people carry their PSP's to work and on thursdays when the store updates, they start up all the downloads they want on the PS3 from the PSP using remotely. Once they get home, they get home their stuff's done.

I also like the option of setting the system to shut off after downloads. It even auto-installs any demo's and games that are downloading or even already downloaded. [you do this by using the shut down ICon on the XMB in user menu]

I've tried the remote play feature and it really isn't all it's hyped up to be. If you're playing a fighting game, like BlazBlue, then the lag is is too horrendous to even play it. Slower paced games aren't that bad like RPGs. It's a neat feature, but the lag is kind meh for a lot of games.

It's tolerable in platformers like Crash Bandicoot; you just have to think ahead a little bit.

well someones tweaking, lol glad your enjoying one of PS3/PSP's most awesome-glaxed feautres.

O_o all these games work on remote play?
damn you wikipedia , i didn't know!

Edit : Oh! not played goddamn , i was just trying to play Oblivion just now
