libSceMsgDialog technical debt

Silent stubs

• libSceMsgDialog - message dialogs show no UI. sceMsgDialogOpen opens one without sceMsgDialogInitialize as well, and a user message or system message dialog finishes on the second sceMsgDialogGetStatus or sceMsgDialogUpdateStatus call; the first 160 characters of a user message are only logged. The button it picks (2 for YES_NO_FOCUS_NO, otherwise 1) is kept but not returned, as sceMsgDialogGetResult is exported by libSceMsgDialog.native. A progress bar dialog runs until sceMsgDialogClose or for 30 seconds, and sceMsgDialogProgressBarInc, sceMsgDialogProgressBarSetMsg and sceMsgDialogProgressBarSetValue ignore their arguments

Unknown function info

• sceMsgDialogOpen (libSceMsgDialog) - the SceMsgDialogParam layout it reads is not measured on a PS5: the mode at 0x38 (1 user message, 2 progress bar, 3 system message), the user message parameter pointer at 0x40, and in that parameter the button type at 0 and the message pointer at 8. A mode outside 1 to 3, or a parameter that cannot be read, is treated as a user message; only Windows checks that the memory is readable, so on Linux any non-null pointer is read. The errors 0x80b80003 (not initialized), 0x80b80007 (busy), 0x80b8000b (not running) and 0x80b8000d (null argument) are not measured either. Closes when: measured on a PS5
