Sorry, sorry, I agree. I was too quick there. But still, it's not just a matter of architecture, it's a matter of OS, right? A Windows PC has exactly the same architecture as a Linux PC (in fact, it could easily be the same PC), but software written for one won't automatically compile for the other.
If it were really that easy, I'd think there'd have been an official PS3 port of ScummVM ages ago.
Or, if it is that easy, why don't you make it? :-)

If you're talking about the Linux version. It works already... it's just not pleasent to use.
If you're talking about the GameOS version. I can't. I don't have access to the development tools and seeing as I don't have a product that I could sell (in difference to GoG, which has dozens of products) I probably never will.
As for the complexity of such a port... it's minimal. As the PPC architecture is pretty well supported, porting something like an emulator over is a relatively easy task, as it doesn't really use anything provided by the OS, except the basics like memory and process managment (which work pretty much the same across all OS), simple framebuffer drawing (would need to be adapted, but it's really very, very simple) and input drivers.

So what you're saying is, that the way Sony has set it up, there is no freeware / open source development for the PS3, and can never be either? You have to be a commercial entity to even compile something for the platform? Yeah, that sounds like Sony, actually. It's stupid, and it's keeping a lot of people away from the platform, but these are the people behind SecuROM, after all.

That's exactly the way it is. There are certain (monetary) requirements for entering the console market, and that means that individuals or small projects can't. Opensource itself is possible, but you need commercial support. And of course a license that allows use in a proprietary environment with proprietary libraries (GPL does not, BSD does).
Consoles are a protected environment, you can't do business on them like you would on a PC, but you can do business on them.

Yes, so I understand. My major antipathy arises from the fact that you can't even do non-business on them (freeware / open source). That sucks tremendously.
