I've just published JTerm, Jrioni Terminal Emulator on android market.
This is to bypass android framework and support gp2x mode (direct kernel interface, no Java/JNI/Runtime lib…etc) for all emulators/gp2x apps.
To toggle between Android <-> Gp2x mode, you need to press track ball down + Enter.
(assuming track ball is set to ctrl key)
This is for beta-testers only for now.
(you can buy it but public version will have to wait till beta-phase is over)
