JBit is a MIDlet (i.e. an application for the J2ME platform) that can be used to edit and debug 6502 programs on your mobile phone. You can also develop a 6502 assembly application on your desktop and deliver it to any MIDP-enabled device.

Changes

The editor has been improved and now you can resize the program and insert and remove instructions. A minimalistic IO chip (MicroIO) has been implemented. It can replace the standard IO chip on old phones, leaving more memory available for programs.
