Hello fellow Heroes, it seems that the "QfG Anthology" manual is (partly) corrupted - page 32 (or 30 - "Dr Cranium's Formulas"), to be more precise. Bottom half of the page is missing, I also get the "Insufficient data for an image" error in Adobe Reader.

I'm getting the same thing in Foxit. No error message, but that second half of the page is just blank.

Usually GOG manual cockups are due to bad source website, but Sierra Help Pages have the manual in unbugged form.

Great, thanks for the link.

GOG had better replace their corrupted version with that one. That page corruption cuts off half the copy protection recipes for QFG4.

Thanks, grviper.
Please fix this particular issue, GOG. Thank you in advance.

Thanks for the link. I noticed that GOG only includes the VGA version manual for QfG1, even in the QfG1EGA installation folder.

The separate Anthology manual "extra" appears to be the same as the sierrahelp.com one, except with the last two pages (support and back cover) removed. This is probably intentional, to prevent people from trying to call a defunct Sierra number instead of contacting GOG for support.
