Segher&I hand-dumped the rom and I've done a svg of the lcd.
That pic reminds me that to learn more about the MCUs in the R-Zone Ranger sent me, I decapped the handheld LCD games TopGun and TMNT, which used similar Sharp chips: http://www.seanriddle.com/tiger.html

The ROM for TopGun is on my page as well as a scan of the PCB. If anyone's interested in emulating those games, I can figure out how the segments of the LCD are controlled and I can upload TMNT.
