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.

[2017-03-03] Release 2.4.14.734

This release fixes incorrect handling of mirror failures introduced in last release.

[2017-01-25] Seemingly missing files and random RO client crashes after patching

After updating a Ragnarok installation with the official patcher or with RO Patcher Lite 2.4.7 or older, the following symptoms can occur:

  • the client crashes either during start-up or in-game
  • the client reports missing files
  • sprites or textures appear corrupted

This can be caused by too large GRF archive. The RO client and most GRF tools cannot handle archives of more than 2 GB in size and depending on the archive layout and the file being requested, the above issues may occur. The issue can be remedied by repacking the GRF archive with the command line option /repak or with GRF Diet Plan. You might want to update to RO Patcher Lite 2.4.8 or newer, as these automatically repack the archive when it reaches the limit.

[2017-01-15] Release 2.4.12.727

This release improves download performance and stability, and fixes minor UI glitches and memory leaks.

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.
