I always wanted to play the Progear one. They even advertised it with a "Cave" branded image of a flip-phone.

I posted a pic of the flyer that came with Espgaluda on PS2 here: https://www.instagram.com/p/B63QZfgnGse/

I'd be curious about this as well, as one assumes they were done in a JAVA/BREW type of environment, so they should be relatively easy to emulate on most anything now.
