+[OnFrame]
+# In function `WaitForToken` there's a loop that continously calls
+# `GXReadDrawSync`, waiting for it to reach a certain value.
+# However, if the loop is executed 10000 times without that happening,
+# then it timeouts and proceeds anyway (with broken graphics).
+#
+# The logic for the timeout prevents Dolphin from idling during the loop.
+# The patch modifies `WaitForToken` to remove the timeout, allowing
+# Dolphin to idle and improving emulation performance.
+#
+# As a side effect, this allows to use hacks that affect the emulated CPU
+# clock without the graphics breaking.
+#
+# Note that there's a function that calls `WaitForToken` with nonsensical
+# arguments (is it intentional?). Normally, this is escapable due to the
+# timeout, but since that's removed, it freezes the game.
+# Thus, the patch nopes out the nonsensical call.
