idk if this is the same thing, but there is an app called "Java J2ME Explorer/Manager".
Basicly opens java app store with Java/J2ME files for Andriod. has 1669 java apps, all free. I found alot of the old games I got from T-Zones on my old nokia 5300 on this app, and was able to download them and play them.
Although the framrate is pretty slow, and I can't figure out how to control the games with anything other than the trackball (roll for u,d,l,r, press for enter) its a shot in the right direction.
at the same time idk wtf im talking about, so this prolly isnt what you were looking for lol.
