RagnarokOnline Patcher Lite (c) 2009-2017 Ai4rei/AN

Replacement for Gravity's RO patcher. Works faster and doesn't consume your entire memory for just seeing it crashing, aside from this, it works almost exactly as the official patcher does, so that it shouldn't break, unless Gravity changes something vital to their patcher. It is free of any cost and works on every 32-bit and 64-bit Microsoft* Windows* platform.

[2016-05-14] RO Patcher Lite's future and the ELUR Project

For some time the 2.x branch has been limited to bugfixes (except maybe the mirror support). There will be one more update to this branch, before it is limited to critical bugfixes1) and occasional refreshes2) only. There are also no changes to the fact, that the 3.x branch is dropped. The 4.x3) branch is on hold until ELUR is released and stable.

Now, what the heck is ELUR? The ELUR Project is a suite of universal auto-patcher applications, based among others on the RO Patcher Lite and ROCred code-base, that are distributed under a less restrictive extensions API. The point is, that RO Patcher Lite is only for updating on official RO Servers, the ELUR Project is to satisfy specialized patching needs, and mixing those made a mess of the original code-base. There is currently no ETA on when it will be available.

And to close with some rants, the kRO mirror backup/load-balance server closed last month with 63GiB of traffic; free things sure are great, aren't they?
  1. There were not many of those since the public-release, as this reflects only worst-case bugs, ex. OS incompatibilities.
  2. When enough significant shared code-base updates accumulate and the binary has not been updated in a long while, a "refresh release" occurs. A long while can also be 2 years.
  3. Full rewrite to separate UI/misc from core, also includes liniris and general *nix support.

[2016-01-09] Release 2.4.8.670

This release adds support for ASLR and DEP, improves kRO mirror balancing and the GRF repacking scenario.

[2016-01-09] Windows 10 issues with HTML patch news (panhtml)

When the update KB3132372 is installed, a patcher enhanced with the HTML patch news plug-in may crash, if the patch news contain Flash-based content. This is a problem in the flash control (issues DebugBreak when SetProcessValidCallTargets fails) and unrelated to the patcher or the plug-in.

Mirrors

As some countries seem blocked from using the official kRO patch server, the patcher offers tamper-resistant patch download from community contributed mirrors as fall-back mechanism from version 2.4.5 onwards. Anyone willing is free to apply for inclusion into the list of approved mirrors. Patches served through mirrors are subject to delayed release due to technical reasons.
