This is similar topic to just with it u can decrypt 1.5.2.2 version files.

 

 

Everything same just source code different:

	else {

 SmartDecrypt.dll must be before npkscrypt.dll

If u want decrypt example interface.u/xdat/or other file then just rename it to SysString-e.dat and run l2.exe (you will get error just click ok) after all in system folder must appear decrypted_file.txt. (this file will be encrypted with regular l2encrypt (413/111 and etc..)

Hi, I got the error "invalid pe file possible reason: no export table present" in CFF when I try to add the dll file in L2.exe, any idea what's happening?. btw I used vs2013 

I appreciate your support

    • You think you have good “l2j” files until you try running a low-rate server.   Saying “there’s not a single L2 server out there worth mentioning” just shows you probably only know the first 10 servers on voting sites, the same voting sites that owned by them. You call the forum dead, yet you’re here discussing your next projects… From my perspective, you don’t seem ready to run any L2 server in 2025. Around 70% of players are here for RMT or ask for payment just to bring their clan, and you really think the community cares about Premium or donations or files quality? The other 20% spend their time downloading and deleting servers all day, playing for one day, then quitting for whatever random reason. And finally, the last 10% are the only ones who actually play because they genuinely like your features, your server files, and your overall project. Good luck 🙂
    • I genuinely admire your bravery - in an age where AI can whip up something better in under a minute, you still stubbornly try to sell these "projects" of yours on a forum that’s been clinically dead for years. That’s no longer determination, that’s digital archaeology. I just can’t tell whether you’re actually trying to make money, or simply testing how much we can endure before we ask an AI to generate you some actual talent.   And ofc AI will make it for free, $220 saved.
    • I’m glad I’m not the only one who appreciates Maxthor’s involvement in group gay orgies, he can’t be bothered to reply to messages, but covering the entire forum in gay lights is absolutely no issue for him. As for the project - the forum is packed with feedback from the testers, the lads are spending every spare moment fixing even the tiniest typo in an NPC’s text. I’ll share the links as soon as I get the green light. Edit: I forgot to add that the GM recruitment will begin once the links are released. Three people will be accepted, and they’ll work in a three-shift rotation so that there’s always a GM available online.
    • Added: a brand-new default dashboard template. You can now add multiple game/login server builds. Full support for running both PTS & L2J servers simultaneously, with switching between them. Payment systems: added OmegaPay and Pally (new PayPal-style API). Account history now stores everything: donations, items delivered to characters, referrals, transfers between game accounts, and coin transfers to another master account. Personal Promo Code System: you can create a promo code and assign it to a user or promoter. When donating, a player can enter this promo code to receive bonus coins, and the promo code owner also receives a bonus — all fully configurable in the admin panel.     Look demo site: demo
