OK, so it turns out that after 25+ years someone (me!) finally realized that Solomon's Key on Automation CD 25 was, in fact, broken.
Not really a problem, as SHW patched it for falcon many years ago... except.. this is where I sourced the binary for the Jaguar port...
Anyway, rather than rain on SHW's parade and use his (Plus, I looked at his version and... WTF DID YOU DO PHIL?? I CAN'T SEE BOLLOCKS!!) I grabbed a fresh STX and did it all again.
Also, I noticed if you got a high score you couldn't enter a name because the keyboard is missing on the Jaguar (Stoopid Atari - how can you 'do the math' without a keyboard??)
So, have at you with a fixx0red version, not that you asked. But when you do, here it is.
