Back in 2007, I wanted to use Droplets to represent explosions in JSW64MM: James Bond (specifically "You Only Live Twice"), but for some reason, I couldn't get it to work, regardless of whether the byte at 0:#FF61 is 00 or 08. This game is based on Variant Z.

However, I have just discovered a bug in JSWED v2.3.2 that converts Skylabs to Droplets on a guardian-by-guardian basis!

I just tried adding a Skylab to "You Only Live Twice" [4], resulting in the following hex for the guardian:

08 62 00 40 04 9D 10 60

But if I edit this using JSWED's guardian-editor (even by using '!' to add it to a fresh copy of JSW64MM: James Bond v1.1), it changes the second byte to 02 when I click "OK", resulting in the following guardian, which behaves as a Droplet:

08 02 00 40 04 9D 10 60
