Undisappearing for this:
http://members.tripod.com/tokyo_garakuta/nichipon.htmThe link above is an archive of communications within a Japanese scene community. It's 100% not translated right now, but there are 23 references to Chrono Trigger, and one of them is someone telling another person that they'll check if their Chrono Trigger build is the final if they send the ROM (with the final build date, per the poster, being January 20, 1995).
The implication is that whomever he's addressing may have a
non-final build...the Prerelease, or maybe even a different prototype.
We definitely need all messages containing "クロノ" or in response to those translated ASAP! Put out the call if you know someone who can read and assist. It would be fascinating to find out there might be another prototype of CT out there, buried somewhere in Japan, perhaps rotting in some collector's EEPROM bin.
