yes, those are all Ubisoft games, and are free because ubisoft has chosen to make them so
they are not abandonware
secondly, what do they have to do with this topic, absolutely nothing, so please stay on it.
it is illegal to download PSX games, no matter what, even if some site says the PC version is available doesn't mean the PSX version is.
let me put it this way, any more talk about the downloading of PSX games in this thread, and it will likely be closed by one of the staff.
