Hi, folks. Here's something interesting I found. We know that LoF has a hidden 3-D glasses mode (Hold 1&2 on power-up), so I tried it out. However, the 3-D mode didn't work on my Japanese SMS.

The 3-D glasses register(s) are $FFF8-$FFFB, right? (At least that's what some SMS docs say.) Every 3-D game seems to write 00/FF or 00/01 to $FFFB, except for Line of Fire, which writes this to $FFFA. So, I varied the write address in LoF and tested the 3-D glasses on my SMS. $FFF8-$FFFA don't work, but $FFFB works fine. Do export SMSes have the same limitation as my JP one? Or do any writes to $FFF8-$FFFB work with the 3-D glasses?
