ZaxMidlet
Note: Zaxmidlet is deprecated. Current work is on JFrotz for J2ME.
Note 2/10/2012: ZaxMidlet is no longer under current development and will be replaced by JFrotz, which is a Z-Machine interpreter based on the Frotz engine for both J2ME (Blackberry) and Android. http://sourceforge.net/projects/jfrotz/
JFrotz uses more memory than ZaxMidlet, so Zaxmidlet may still be the best choice for users with relatively low-end J2ME devices.
ZaxMidlet is a midlet Z-Machine Interpreter for Blackberry and other J2ME devices that support MIDP2.0 and file access. It is based on Zax 0.91. It plays V1-5,7,8 Infocom and Inform games. For OTA Install goto http://sites.google.com/site/zaxmidlet
