What the firmware sets up for the ME at boot, which mcidclan's custom-core libraries rely on, at kernel init when the ME is emulated: - Sony's ME image at 0x88300000, as me_wrapper loads it: meimg.img on a PSP-1000, me_t2img.img on later models, from the installed firmware's flash0:/kd/resource, decrypted and KL4E-decompressed (only the first of its two streams, the code). Custom-core calls functions in it, picking per-model address tables by the word at 0x18. Without the firmware it's logged and left out. - A "SceMeRpc" sysevent handler record, which sceKernelReferSysEventHandler (new, sceSysEventForKernel) returns, and custom-core takes over. Also the VME's control registers (0xBCC00000), kept, with the status at 0x10 reading as done: custom-core's ME startup writes 1 there and waits. mcidclan's custom-core poc, hw-mutex, gu-shared-list and exceptions samples now run.
