Square-Enix bought Eidos a while back.

They should play on the PSP as well.

Exactly, they are both $9.99 on PSN (just logged in to double check, because I thought they were actually cheaper). What this means to me is that the PC versions could potentially appear here, since the price-point would be identical. However, I have no idea what Eidos thinks of DRM (or lack thereof on GOG) or anything.

Oops, I missed that someone already pointed out the PSP option. Sorry bout that.

aren't emulators illegal or something? If not where can i find a good one to download from a safe place?

To my knowledge emulators are not illegal as sure. The ROMs (backups) that you play are for backup purposes and thus to play a ROM is illegal.

That is my understanding though I admit I know very little about the matter and may be completely wrong.

Emulators are not illegal. ROMs and ISOs may be however, depending on local law. Whether it's right or wrong is independent on the law, and instead depends on personal viewpoints (often the consumer's viewpoint is not the same as the copyright holder's).

Emulators, for the most part, are as "illegal" as ROMs or ISOs. Because to properly emulate a game system, you need access to certain files of the original console OS. Those are not freely distributed. AFAIK none of the "big" modern consoles have become "open source".

Even if you own the game and the console, it is, strictly spoken, still (in most countries) illegal to download roms and/or emulators. Copying date from the console to the PC in order to get the emulator to run is rather gray, to say the least.

But walking a red light is also illegal...

Edit: Most emulators you can find on the web, do not contain the aforementioned OS files and a therefore legal. So Miaghstir is also right, but you can't use them without the file. So getting an emulator to run on a pc is illegal (for the most part, see above) would be the more correct term...

Emulators are perfectly legal. Illegal ROMs and ISOs are not.

Look for example on homebrew sites for legal roms

Yes, the BIOS/CMOS/whatever, they were meant to be included in the ROM reference, though that was unclear. The legality still depends on local law, in some places I'm sure it's perfectly fine to copy them from a console you own no matter how much Sony, Nintendo, or Microsoft would like it not to be.

Yes, in Germany this is perfectly legal by §53 UrhG as long as no working copy protection is broken. You could argument about this in the case of NSMB Wii, for example, but I would not call four bytes in a boot file that make a Wiimote disconnect after 10 minutes a working copy protection since theoretically you could still play it from beginning to end although with some hassle.

Note however that it is not permitted to give ROMs/ISOs to friends or distribute otherwise. But dumping your owned games and playing them is perfectly legal. If you re-sell the games you will have to destroy all other copies of them, though.

Actually, you also want to look at the §69a ff. UhrG, as they are the relevant laws for computer programs. But generally what you said is correct. But I wouldn't flat out say that "dumping your owned games and playing them is perfectly legal". Especially if a copy protection was made to specifically prevent that (but I think that started after the time of the PSX) .

Oh, and read § 69d II UhrG iVm § 69g II UhrG for a warm an fuzzy feeling ... ;-)

I don't see the issue about 69d II UrhG, it says the same. Only that it also more or less explicitly states that you are in any case allowed to make such copies. I mean, physical media always sooner or later will break. Although cartridges and CDs hold longer than they were originally supposed to here. There are some from 20 years ago that still work fine. But of course, at some point they will break.

And for digital media of course you also need copies. I mean, having them on only one HD at the same time still has a certain risk - although in the worst case I'll re-download my GOG collection :D

As I understand it, it's not the emulator that's illegal, it's the ROMs. Or, more specifically, ROMs that you didn't rip yourself.
