The link is to the CrimsonFire message board, asking Treo owners to speak up if they want GBC support for their device. (It is not supported because of the resolution, but Game Boy Color games would run at real size in 160x160 if we could get the developer to make it work). Unfortunately, there are no replies, presumbaly because no one knows about it. (Well, one reply now). Maybe if enough people post replies, the developer will see the interest and make the emulator compatible with our Treos!!! That's essentially an extra few hundred games for the Treo platform!!!
