Just because you can't easily find a game in EB's database doesn't mean its there. You just have to get creative locating it since the search engine has been programmed not to show any hits for certain older titles (Not sure what detirmines a game's status, I haven't seen any patterns).
For example I was trying to find Ferrari F355 for the PS2 earlier, which appears to not be in the system. But its able to be located by looking at the PS2 section by genre and then setting it to show backordered products. And if there were other Ferrari games available, you could've searched for Ferrari and had it list backordered products to reach it (Which didn't work in this case because nothing else available in the system has Ferrari in the title).
Here is the Red Star, which can be located just by entering the name in the search engine (Hasn't been removed from anything), along with Samurai Showdown V for the Xbox.

Lots of copies available close to me, I'm not sure why you think these aren't there.
