Functionalities

Protocol

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
