The History of Duping | Diablo 2 Dupes & The Temp Perm Method | Coooley 

I remember all my "rich" friends doing this stuff. I was never smart enough to know how it worked and was too busy getting scammed all the time.

The amount of times I perm'd without understanding how it worked!! Loved it, great video.

This explains the reason why people use to just ask to trade all the time and then exit the game in trade games.

I honestly think devs are leaving exploits in the game deliberately and then selling items on the side. These item selling websites have a seemingly unlimited supply of items with perfect rolls. It would be trivial to determine who these people were, ban them permanently, delete their items and patch the exploits they're using. The fact that this doesn't happen suggests corruption at the company.

Playing D2 for 20 years never knew how it worked...GREAT video man :D

You're making such an end game content that we don't usually see on other D2 youtubers. That's really great and it bring back a lot of memories. The bugged part of D2 + d2jsp is probably why we loved D2 so much and kept playing it for so long.

Man, you gotta make more of these. I'm too young to have experienced many of these patches but the history behind them is amazing.

When I first started playing d2 back in the day, probably 2001 or 2002, I had dial-up internet. I would give a friend an item and then immediately unplug my phone line. When I reconnected and made it back into the game we would both have the item. This was before we had heard anybody talking about duping, and we never lost any of the items. And to this day I've never heard of anybody else duping this way.

I remember some other duping methods during the years I played (2001-2006). The easiest one was to use a sorc to casts meteors and a necro to cast bone walls until the game was lagging so much that you could drop an item on the floor, leave the game and still find the item on the character, while someone else in the lagging game could also pick it up and leave the game!

When I was a kid in 1.09 or 1.10, duping and poofing were so over my head, it took on a lot of mystery and superstition, and fear for trading in sojs or hrs. Good to know some more detail on why that went on

Thanks for making this. I started playing Diablo 2 since the initial closed beta and never knew how duping works. Got all hyped today after they announced D2 Resurrected. I hope to see more videos from you about Diablo in the future!

Closest I ever got to duping an item was selling one full rejuvenation potion and buying back a whole belt full.

I've played D1 and D2 since day they hit the shelves. With D2, I've seen the many waves of dupes and method of doing so. Pre-Expansion it was all about the SOJ. We didn't have ladder resets or ways to clear out items from one season to the next. So, SOJ's were duped via the trade window method, the horadric cube method, and the vendor method. SOJs as a result just became the currency of the game and due to the duping, rapid inflation where gear would cost 2-15 SOJs. With the introduction of Expansion and later unique item ID, they really tried to ratchet down on it, but it took many years to finally get it somewhat right. However, I think a lot of the weird latency issues you experience nowadays in the game are as a result of these anti dupe/cheat methods adding additional overhead to the server processing your request. Which does things like leave your barb stuck in a perpetual WW or weirdly ignoring your cast on a caster. I've worked in the computer programming and software engineering world for over 20 years, so I can tell you first hand the struggles with dealing with legacy code. I have to imagine it's very daunting to propose any changes to it without introducing new bugs, unexpected behavior, or changing the gameplay in a way that it ruins experience for players. In my world, I deal with a lot of legacy COBOL code, and you face the same type of problems and it basically results in just trying to get the code to as near "stable" as possible and then just putting it into stasis and not touching it.

Ohhhh my lord I’ve been playing this game for a long time and have heard about these strats. But no matter where I looked I never found the video that I was looking for. The day hath come where you have delivered. Long live coooley

Jesus I remember being a little 13 year old scared of losing FOH sticks so I permed every single time I life a game. What a blast from the past.

My dad and I used to dupe items back in the day. It didn't work on Closed Battle.net but would work for Open Battle.net and TCP/IP games if I remember correctly. Your character gets a save file somewhere on your machine that you would make a copy of and store elsewhere. The method was to enter a game with another player, drop everything, shutdown your game, replace the new file with the "original copied" file, and load the game back up. All items are now on your character and on the ground. You could dupe exponentially with this method but we never did anything since we mostly played TCP/IP games with each other. Anyways, that was my memory of duping in D2. :)

Hey I love the vids man nice to see someone giving a little back story about such an amazing game but I would have liked to of seen more about like how it affected the ladder and what ladders were just ruined because of over Dupped items or maybe like time lines and specific items that were duped either way love the vids bro

Ty for the content man. Appreciate. Haven’t seen other people talk about this.

Recently discovered your channel and its awesome! Its great to have this kind of D2 content rather than just drop highlight vids. You gained a youtube and twitch sub from me.

All these terms I’ve heard for years now I finally understand!!!! Thank you sir!

I always wondered what the purpose of perming was back in the day. So cool! Great lesson :D

This is a great video! In depth and well explained thank you :D

wow never knew about these. haha still learning something new about D2 every video. great video as always

I’ve been temp perming my entire D2 life, and never knew how or why it worked. Thanks 😊

honestly i was a kid when all this happened so i never got to experience it but i'm glad this exists as i love hearing about the history of events in games such as this.

This vid brings me back to my bugged bowazon in 1.09 with 6os WF, 2os shako, 4os valor, 4os SS, and this awesome cliffkiller bow amulet that i had to perm every game to keep it around 😂 id give my leftnut to be able to see all the screenshots i had back in those days but they are long gone now

hehe what a trip to the past There was also a way of creating lag with a bone necromancer and a meteor sorceress if I'm not mistaking Nice bugged tal armour and nice video mate, glad I've found your channel, keep it up !

I remember hanging around an ingame character that showed me he was wearing Constricting Rings about the 1.09 era. He personally called me on the phone and taught me how to setup Pindle-Bot and gave me all bugged 1.08 and .09 gear to play with. Accounts were eventually given away to random players after I burned out.

This was incredibly made. Keep it up.

Great content dude. Keep the great work up!

I remember in 1.08. They duped the eth zoded blue Balrog sword. It did more damage then grand father and had 40 ias for whirlwind break point. It was game changer for barbarian pvp. They could actually kill zeal and shape-shifting druids toe to toe and they could kill bowazons still hardly. I remember when it was patched and they all poofed. All the top gear barbarians with the eth blue Balrog blade were a bit sad. I stopped playing my barb for a while.

Thanks for making the video. Really enjoyed it

This was a very good video. Informative, articular, coherent.

Great vid! Loved it!

Just when I think I can’t learn anything new about D2... thanks for the vid!

Omg after so many years later I finally understand those mysteries thank you

Only quality information from you Coooley! I love your videos

"Bro you found an Soj give it to me I will dupe it for you." "Ok I will be right back after I dupe it." I feel like back in the day this was the version of dad going to the store to get beer.

This is top D2 content! Super in depth

Love this history of D2 series! You’ve earned a sub! But I have to ask, is there somewhere I can find your background/intro music? It’s so chill and catchy I’d love to listen to it while working lol

LOL!!! Me and my buddy duped way back when using D2 Loader, opening multiple game instances etc etc, we literally ran the playground when kids found out we could do a very similar method to this, I recall being followed around all day everyday for 3 days by kids begging me to teach them. I love how half of the people we would trade items would never perm their items LOL. GREAT VIDEO!!! P.S. We started running into issues with items packets clashing and items poofing even when permed.

Really interesting! Good job! :)

It was game of patience charsi duping while using 56k dial up connection!

Ohhhh. The first one explains why you can’t trade all the charms on your inventory. That Tal´s armor is insane!

Cool video, nice to go back down memory lane with old d2 banter. I only ever was able to dupe in diablo 1 tho. But I do remember having like 400 3-20-20 scs in d2 at one point and most of them poofed lol.

Used to dupe so much on d2!!! Enjoyed the video!

great vid, what about a video on rollbacks (i.e. a5 clay golem spam)?

I remember people saying “duping items” And the they just scammed the poor fools 😂

WOW great vid, subbed !

Very informative, actually, thanks!

great vid man

Appreciate the videos. Subbed.

This explanation is very, very good

very informative! as an old diablo veteran i subscribed :)

good old days, brings back memories

great vid lol ty for helping us understand the exploit of the old game :)

Top tier content my man.

The "duping methods" you mentioned in the video were all out in the public and were patched within a matter of 2-3 days iirc. I quit D2 not too long after the release of 1.10. For many years I ran under a big time duper who used a method that's not any of those you mentioned in this video. While I ran my own website (alongside the dozen or so websites by others) doing retail at the time, I also did wholesale, or you could say that I was one of several who did the wholesaling for the boss. Those were the good ol' days. ;-)

Love ur vids!

Nice Hero Editor clip :)

Damn how much research went into this video? Or perhaps you just know it all!!! Cool video Mr Coooley

Cool video, most hidden secret in diablo 2. been playing since .09. Lots of other methods ive seen on youtube in the past bonewall psn nova meteor, golems all over ground lag server.

I miss those days when diablo 2 players used duped SOJs as currency for evaluating values of items.

Very good video !!!!

@Cooley your channel is a perfect gem for diablo2 fan like me

This actual duping footage from 1.13 patch. It's crazy to think that I was playing D2 back then, I knew about packet sniffer and blocking, I even knew those packets because I used to do some hacks that relied on packets and mess around with bots and stuff. But I never realized that trading window can be used to dupe items that easily. What amazes to me the most is that if I had heard hints about this method I would have had technical knowledge to pull this off without needing anyone to explain me packets or tools needed. I just never realized that I was seeing a duplicate set of items in trade window.

"The History of Duping" Project Diablo 2 community: Hold my beer

Quality info per usual

best channel for d2 hands down.

i thank god and youtube every day for showing this channel to my recommendations

thanks for the nostaliga. made me play again.

I still remember paying 25 sojs, that I legitimately traded for, for a grandfather that disappeared in the next game..... I was so furious.

Great stuff

This brings back memories. All the "100% legit, found it myself" duped items from the past.

I used Charsi dupe method and I loved it a lot! Then there was a method of selling/buying items from vendors but this method made bugs when selling/buying windforce or some other bows. All public dupe methods were fixed quickly but the time when they existed was really brilliant and awesome.

I used to dupe sojs in the thousands many years ago. Also duped btals, pre-patch rares and other items. Sold those items online and bought my first car with the money I earned. Thanks blizzard

Thanx for the D2GA info! Anymore cool places like it?

Great video

I remember duping c grips and doom looms all day back in high-school hahaha

Wow so this answers why after I permed in a trade window how I still lost 40 Bmana Scs back in the day... someone else permed after I did and left their game before me.

2400 stones of jordan have been sold on this channel Uber Cooley walks the earth...

nice video! Are you familiar with the rust storms blizzard did? Should have covered it as well :)

People were duping stone of Jordans and using them as currency. I just wanted two for my paladin ffs.

I contributed to finding the trade hack and anya WP dupe. One of the first to develop it.

ahhh this brings me back...

Can you make videos about hacked white ring on battle net or hybrid runewords? It would be interesting to learn how they technically worked. Specially if there is some actual video footage left somewhere in the internet.

I duped using packets and selling to the store. Back in the oculus rings (occy ring) days. Was when the dupes went public so I wasn’t special but was still fun to have mules just full of sojs lol. I remember having a special amulet that I could only have one per mule. I forget what it was but I was scared to use them and lose them.

Good to know after 20 years :)

Anybody remembers the Fire sorceress/Necromant bonewall method. I remember this one got public and destroyed the economy as well as made the game unplayable for a while, since half of the batlle-net was duping items and most of the servers were lagged as hell :D Times when High runes were sold for 6x Hel rune.

Those were the best days. Had like 20 mule accounts full of SOJ's and ITH weapons. Anyone remember Carrion Song bow? LOL

I'd love to hear you talk about how people cheat other people's items. You know, exit trade window just to replace it with a junk that had same graphic.

Little Freudian slip when you said "we" haha

My buddies had a lot of fun pwning and trading for years :)

Diablo 1 duping was the g.o.a.t. Let me click this item and drop a potion real fast 🤣 As always thanks for the great content man 💪

Very cool! That .08 server lag...😂

coooley, I think you should make a video about the old scam methods, i used to do many as a edgy teenager and would like to share them

great content

Somebody remember when a bug was found and using act 5 second wp was bringing you to uber duriel stage? Hundreds of baal's eye flooded the game. And it was a suoer fast way to make xp instead of baal's run. It last only few days I remember

I remember SOJ without Level 29 on d2 Classic 1.09d :)

not sure where did you get that footage of dude duping his items, but it's nice to see Polish version of d2 and that my fellow countryman were so clever to actually monetize these xploits :)
