It is possible to interact with SDbgp from host computer via PSP2TMAPI. See Dbgp protocol for details.
Background Sysmem Checker
If DIP switch 224 is on, SceDeci4pSDbgp creates a workqueue and schedules the sysmemChecker task on it.
The Sysmem checker performs one check at a time before scheduling the next one (modulo 3). A 20 seconds delay is observed after check completion before scheduling the next check on the workqueue.
The checks are performed in this order:
0: Verify Sysmem heap 1: PhyMemPart check 2: Partition check 3: FixedHeap check
