Right, I have done some testing with the passenger bug using the three SPS English language EU releases (I haven't tested the other bugs).
Here's what I've found:
- the first release of Frontier (or at least the earliest that SPS have) is release 1960, with the date 6.10.93. The passenger bug is still present in this one (allowing you to cheat, heh-heh!)
- SPS releases 0123 and 2269, despite having an earlier date recorded (2.9.92) are in fact later releases, with the passenger bug fixed. I don't know if they are different to each other, i.e. if one fixed some bugs, and the other fixed some more.
- the best release is of course Djay's, with all bugs fixed!
I am curious about the incorrect 2.9.92 datestamp though. Was this the default datestamp on an unexpanded A1200 (i.e. without a battery backed clock)? Perhaps the later releases were prepared on such a machine, hence the incorrect date.
