I was thinking about this earlier (the Spectrum Software Projects 'official' fix) and decided to compare a few versions to see.
As a random off topic note, I also noted that the BBC version is the only one that appears to retain the 'auto collect' object in Swimming Pool too.
Anyway, the Spectrum original, as you can see its got the four 'Fire' cells still:
Here is the fixed version of the same, I actually just used the 'They Sold A Million' re-release (the one that's curiously Speedlocked) as the 'fix' is the same, one Fire cell gone:
Now lets take a quick look at the Spectrum version of JSW2, this follows the Amstrad CPC version as expected as it was based on that from what I understand. There's just two Fire cells:
Taking a look at the Amstrad CPC version of JSW1, we can see they changed it a little bit (possibly for the better?) with the four objects and only two Fire cells:
The Amstrad CPC version of JSW2 follows the same pattern too:
The C64 version of JSW1 follows the Spectrum 'fix' in this with just one Fire cell removed:
The C64 version of JSW2 is rather more curious with an extended platform:
The BBC version of JSW1. This again follows the Spectrum in just removing one Fire cell:
Finally, the BBC version of JSW2. This breaks slightly with convention as its identical to the JSW1 version (I used the 'full' expanded disk version of this which contains nearly all the rooms including the full mansion)
