:The ARM11 kernel [[Memory_layout#ARM11_User-land_memory_regions|initializes]] the MMU tables. "Also, is there any method to let the core execute those commands (that you detected) and use that to produce something you interested in?" By running code on a 3DS of course. --[[User:Yellows8|Yellows8]] 17:27, 17 June 2013 (CEST)

::Thanks. But still feeling strange of that strategy. I think at least the Home Menu may be able to re-map or deactive this mark.

::-snip- Sorry for being noob (i would try learning arm soon). Hope you good work.--[[User:Syphurith|Syphurith]] 02:46, 19 June 2013 (CEST)

Home Menu starts application processes via [[NS]], terminating and "suspending" process execution(the process is still running with that, the application threads wait for a [[NS]] notification for resuming actual execution) is done via NS as well. The ARM11 kernel handles mapping the processes' virtual memory for .text, .rodata, and .data. The ARM11 kernel handles terminating processes as well of course. The only process which has access to [[SVC|svcControlProcessMemory]] for mapping memory or changing memory permissions, is [[RO_Services|RO]] module, and of course that module will only map R-X .text pages for the signed [[CRO0|CRO]] .text. --[[User:Yellows8|Yellows8]] 03:16, 19 June 2013 (CEST)

:One of my friend tested that minutes ago. He said he tried to open then close MH3G for 9 times in a row, while he found no significant difference between all the execution time (i mean he found it seems to take the same time to open and close).

:I can still remember ns/ro is also a title in title list. (if manually start that may fails/cause failure) if you launch a title with those commands manually, would it be exposed (in ram?)(, if so we may dump the firmware/modules)? MPS let multiple processes can share the same resources (with home menu?). or have we to modify the real memory externally? There are just thoughts, if interesting please think for a while; if not just tell me "NONE".--[[User:Syphurith|Syphurith]] 05:17, 19 June 2013 (CEST)
:-snip- oh well let me think a while.. about that core.--[[User:Syphurith|Syphurith]] 04:39, 19 June 2013 (CEST)
