From 47e806b084e7eaf44f441c84720d1ca36e12595b Mon Sep 17 00:00:00 2001 From: Yuri Kunde Schlesner Date: Sun, 7 May 2017 14:36:20 -0700 Subject: [PATCH] citra-qt: Remove disassembler widget It has performance problems, a very misleading UI, and is broken in general. It has essentially been superceded by the GDB stub, but if we wanted a built-in disassembler in the future it'd essentially need to be rewritten from scratch anyway.
