@@ -60,7 +60,9 @@ Current known issues / missing features / things to do:
 - There is a function that encodes QST files, but there's no corresponding CLI option.
 - Figure out what controls BML file data segment alignment.
 - PSOX is not tested at all.
-- Memory patches currently are platform-specific but not version-specific. This makes them quite a bit harder to write and use properly.
+- Improve the patch system. Specifically:
+    - Memory patches currently are platform-specific but not version-specific. This makes them quite a bit harder to write and use properly.
+    - Implement the PSOLoad hack to make loading work reliably on real hardware.
 - Find a way to silence audio in RunDOL.s. Some old DOLs don't reset audio systems at load time and it's annoying to hear the crash buzz when the GC hasn't actually crashed.
 - Implement private and overflow lobbies.
 - Enforce client-side size limits (e.g. for 60/62 commands) on the server side as well. (For 60/62 specifically, perhaps transform them to 6C/6D if needed.)
