Dear Jpcsp community!
during the last months, I've worked on a Low Level Emulation (LLE) in Jpcsp as an alternative to the current High Level Emulation (HLE) approach that was used from the beginning of Jpcsp. This work is mostly a proof of concept to document the internal hardware interface of a PSP. The goal is also to have an easier testing of some HLE functions by using the LLE version as a reference.
Frankly, I was not sure how far this way would lead... but today I have reached an important milestone: the whole reboot process of a PSP could be completed and the VSH is showing up!
Not everything is available for now, there is still no sound, no memory stick, no UMD and no OpenGL support... but this is feasable and just work to be done.
Attached are screenshots after the reboot.
EDIT 2019-06-10: using the latest changes, the PRO-C 6.61 CFW can be used: after rebooting the PSP, run once the "661 PRO-C Updater". "CIPL Flasher For PRO-C" can also be used so that the CFW is automatically loaded when rebooting the PSP (i.e. when starting Jpcsp). Custom plugins can also be used (e.g. JpcspTrace), like on a real PSP.
