At one point their main website (was it their website?) had links to box art's from games which may be coming out, among them was Resident Evil 4 and Sonic Adventure. Now it's been quiet for quite some time but someone over at gaf brought the zeebo back into attention linking to a youtube video of RE4 being played on one.
The interesting thing here is that this version of RE4 is 99% the same as the iphone/touch app store version, and that is probably simular to the japanese mobile phone version the other year, but I do know the iphone version had a few updated textures and poly added in.
I then thought about the Sonic Adventure box we seen in the past for the Zeebo and SA1 coming out on xbox live arcade (and psn when confirmed) I started thinking that maybe SA1 is also being ported to the iPhone? it's highly possible because they could use that for both the Zeebo and iPhone if anything like RE4. Just thought I would post what I thought about it all before I forget.
