Hey
@Erayz, welcome to the forum!
Our community is definitely small (give that this is a very unique niche at this point) and I don't try to artificially promote the forum. The only advertisement is really on the Cactus home page and my YouTube channel (The Moving Caravan), and of course word of mouth. I would rather people find the forum organically and want to sign up and stay here. If you know, you know. IMO the forum is as strong as ever and I'm happy to have the people we already have here. If we only got 20 people to play old time traveling versions worldwide that already amazing. If you played MP, you only need 8 people for a full game haha. The bar is not that high and I'm confident over time we will have a consistent 8 player game for people that want to MP on old versions. The forum is primarily single player time traveling, but it's fun to time travel in old versions via LAN

.
Definitely start and continue to show us your findings

, we are always are open to enjoy (and be slightly jealous) of your findings haha.
Regarding 1.09b and d, from my experience and research, all 1.09# versions are compatible. I would recommend backing up your characters and downgrading to 1.09b and using Singling as well.
Regarding 1.05b and 1.06, I was going to recommend not upgrading (at least not for those current characters, but definitely downgrade to 1.05b w/ Singling) if you ever do your own ladder reset, primarily because i know 1.05 and 1.04 are not compatible and there were changes that cause your characters' items to get wiped if you go backwards. However from your experiment it seems 1.05-1.06 are fine which also makes sense (besides the newly introduced 1.06 anti duping code). Since you already backed up your characters and downgraded to 1.05b with no issues, definitely stay on this patch, and welcome to the club!
Finally regarding the lag in main menu,
@Manny is correct that it is related to my multi CPU fix so that your laptop doesn't get hot due to processors back in the day not sleeping and thus using 100% of a single cpu core. This only happens for versions before 1.10, and it's specifically only for the CPU fix in the main menu (D2Win.dll) not the CPU fix in game (D2Client.dll). To fix the lag in the main menu, you should switch to cnc-ddraw as your video renderer. I'm guessing you are using the normal video renderers which seem to not play well with modern versions of Windows for a long time now. cnc-ddraw, Singling, and OpenAL/DSOAL (3D Sound and Environment Effects), are all part of Cactus.
Singling only contains non gameplay modifications and i would highly recommend using it. Singling also includes my players command for versions before 1.09. You can read all about Singling here:
https://github.com/fearedbliss/Cactus/b ... INGLING.md (also linked by
@Manny above).
The Singling page also describes the lag issue and how to fix it, and any other info you should be aware of:
If you experience extreme lag in the Main Menu for versions 1.00-1.09b, try using cnc-ddraw, this should fix it. If for whatever reason that still doesn't work, you'll need to revert the CPU fix for the Main Menu specifically (You'll still have the fix for Single Player and LAN). Simply replace the D2Win.dll you are currently using with the one in the Singling Stock Directory for the affected version.
