So you want to download v0.85.1 and use the save codes in the zip.... Wait. You just played through v0.68.2? You just completed a version that is almost 2 years old.
I have bad news to tell you. The next update after that, v0.82.4 / v0.85.1, had rewrites and revisions at the beginning of the storyline. If you want to play through the new content in v0.82.4 / v0.85.1 you have to start at the beginning because that is where almost all the new content is - it introduces several new characters, restructures storylines, etc - and then there is a bit of additional content at the end.
If you want to download v0.85.1 and play it - follow the link to my archives here:
#29,236 - there is a cheat code for that version for money, etc. But there is no save code.
If you want to just skip that content and just go to the new content for v0.89.8 (Seasons 1-4), again follow the link to my archives, download that version and use the save code in the text file in the zip to start at the new content after v0.82.4 / v0.85.1.
Then when you've completed v0.89.8 (Seasons 1-4), then you want to download v0.95.7 (Season 5) to play all that new content. You won't need a save code for it, because it is a standalone update starting at the new content - none of the old content is in it.
