This article is from the Final-Fantasy and other Square Soft Games FAQ, by firstname.lastname@example.org (Nick Zitzmann) with numerous contributions by others.
Square included a little undocumented goody on the Chrono Trigger CDs.
The file "rom.bin", located in plain sight on the CD, is actually the
full game ROM file of the original Japanese release of Chrono Trigger on
the Super Famicom.
It can be played by using any Super NES emulator that can play Chrono
Trigger correctly in Japanese. If you can't get it to work, try copying
it off of the CD, and try changing the extension from ".bin" to ".smc".
NOTE: This FAQ, and its maintaner, do not support or condone emulation.
Please respect Square's copyrights and do not share copies of this file
with other people.
