Hello there! First than anything I have no clue about websites development, I'm doing this as a "hobby" reading tutorials and checking other people topics that had the same problem and everything is going mostly fine hehe.. My goal is to bring back an online community in which I was an administrator and then owner for a short period of time. I had the best years of my life there (Nostalgia kicks in) and I would love to bring back the forum to see if I can get the "gang" back.
This is the forum back then taken from webarchive;

I know the forum was based on SMF 1.1.11 with SP 2.3.1 and Analysis theme by Crip. The original Analysis is not available anymore but I could get the new version.
My website is based on SMF 2.0.18 with SP 2.3.1 and the new version of Analysis theme. I didn't use 1.1.11 because I saw people's topics using it and most replies to their post was to upgrade it as soon as possible. Can I still manage to get the same old look in the new forum? Most mods from old forum are from 2006-2007 and are not updated ever since. Can I still use them?
My website looks like this so far and here we start with my problems.

As you can see hrd-l.png doesn't seem to show on the header. Also all left side from blocks are missing. How can I fix it?
Also if you could help me where to look to get the profiles on topic to look like this, what should I edit?
Old forum:

Note: Also, I got the awards mod but it says it's not compatible with my version. Should I install it anyway?
How it looks atm:

I know old one has multiple membergroups but when I tried to install it happened the same as awards.
Should I use SMF 1.1.11 to use the old mods without problems?
Also there is a last thing I would like to do
Old forum recent posts looked like this

and atm it looks like this

and I will ask you once again if I should move to smf 1.1.11. Most things I will use on the forum are old, also its a gaming forum should I still be concerned about security? If so, how do I install 1.1.11 using Softaculous?
I will leave Analysis there in attachments!
I would really appreciate anything you could do to help me, I don't expect you to do all the work but if you could point me out where to edit things and where to find the mods I need that would be enough. I have no problem to mess with the files trying to get things right and that's what I will do while I wait for an answer. Thank you in advance!
