RagnarokOnline Patcher Lite (c) 2009-2021 Ai4rei/AN

RO Patcher Lite

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.

[2021-11-05] Release 4.1.4.1282

This release adds support for the new, short-lived (2021-11-03 ~ 2021-11-17) kRO Sakray server. This is a different server from the one removed in 4.1.2 and requires a new full client. There is no mirror support for this one and it is released only as part of the bundle package.

[2021-11-04] Release 4.1.3.1277

This release fixes an assertion when applying optimized patches.

[2021-10-30] Release 4.1.2.1276

This release improves performance on x64 and WINE and removes kRO RE support, because the patch server is gone. You can still update kRO RE with the previous version for a limited time by using the "Always use mirrors" option from the window menu.

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.

Do not provide mirrors for the downloads below, you will end up with an outdated version quickly. Do not hot-link to the downloads either for the very same reason. Link to this section. Thank you.
