I remember playing this game on the PS1 and it was a very entertaining stealth game that would work well on GOG. Good gameplay and evocative settings of feudal Japan. I would love to see it on GOG.

What do you think?

I'd love to see it on PSN for starters.

I don't think any Tenchu game have a PC port...

I don't think that matters. With today's technology it would be easy to convert it to work on the PC.

define easy while still being within legal parameters...

Which games do you mean by that? Cause so far, only PC games have appeared here, no porting has been done by GOG. So which game(s) do you mean by PS1 games?

I don't think you understood the English in my previous post. I said "I genuinely don't know". I cannot be any clearer.

I was asking the people on GOG and you have now answered the question. It seems only PC games are on GOG, which is a shame as there is so much potential in old console games.

No worries. This is more or less what amok was saying on the legal parameters part.
To be able to emulate a console, you need to secure the legal rights to use that console's OS, something that atm hasn't been done (I think). So if a site sells you the equivalent of DOSbox for PSOne, it does need to have legal permission from Sony to use the OS for the emulator, plus (of course) the emulator and game distribution rights.
I am not sure how many console emulators are currently in existance, maybe someone else can answer that.

No need to be snotty. Generally the GOG staff will not answer specific questions on this forum. The best answers you can expect will be from the community. If you want an answer from the staff, write to support.

You are not the only one that feels that GOG should expand to include other platforms. Technically speaking, GOG already emulates another platform - DOS - in many of the games it sells, and aside from firmware issues, there aren't really any legal obstacles to emulating games on other platforms other than the usual rights issues with the games themselves.

Both EA and Konami have sold emulated NES, SNES and Mega Drive games on the PC and other plaforms in the past, with the relevant platform trademarks hexed out.

Thanks JMich - that's very useful info.

On a side note, here's one example: Steam did release Light Crusader - a very old game on the Sega Mega Drive. So it can be done for the PC.

Sega sells it with the emulation, which is within its rights

Err ... what the hell?

Sorry, but you're not getting the full nuances of English either. That's not a criticism as I can't speak a foreign language fluently.

Try and relax people.

Half correct. While many PSone emulators require the use of the copyrighted BIOS, there are emulators like PCSX that use high-level BIOS emulation to negate the need for an actual BIOS. Clean-room emulation of the BIOS is something that Sony would not be able to do anything about.

NES and SNES emulation would be no problem, as long as mentions of Nintendo are removed from the games. PS1 a little more tricky, as the Sony references are more integrated into the games. And in the case of the early Tenchu games, I think Sony has exclusive distribution rights anyway.
I think we're done here until you can learn to be a little more polite.

Just as amok replied, Steam has an agreement with Sega, which also includes the rights to use a Mega Drive emulator. GOG.com doesn't have (yet) a contract with Sega, so it can't sell any Sega game, nor a Sega emulator. Hopefully, that will change in the future, even if I don't particularly care that much about the console games.
