There's actually a list of bromide locations in the Japanese-English differences page (http://www.lunar-net.com/ebc/ebc_diff.php
) since the locations differ for some between versions.
But, the only ones that I think are time sensitive and are technically possible to miss permanently are:
2 - Mia's Bromide (not sure, haven't tested)
3 - Jessica's Bromide (not sure, haven't tested)
4 - Lucia's Bromide 1 (might not be possible to skip because of story triggers)
8 - Jean's Bromide 2
Let me know if you do test those, though, and find out for sure. KF
