Booting PSP in Jpcsp - Low Level Emulation

[onelight]

test Kingdom Hearts Birth by Sleep Final Mix

Are the graphics issues (flickering and spikes) also happening with the "normal" Jpcsp and the external software renderer. I.e. are they related to the "--reboot" option?

Thank you for the video!

graphics is ok when normal Jpcsp and the external software renderer

I suspect this is due to the still incomplete audio support. I have also observed such "hanging" sometimes. I have fixed an audio issue in e044853. Could you please retry?

OK, it can run again

Just my guess, is that graphics issues because multi-threaded rendering?

The rendering through the external software renderer is the same in LLE and "normal" Jpcsp... The difference must come from incorrect timings, also the audio timings are LLE are still far from being correct.

I'm not sure if trying to boot PSP with --reboot is too resource heavy for my computer:

Code:

JPCSP revision: 503d3e6f
External Software Renderer revision: f5f617a (SSE3)
Model (in Settings): PSP-3000 (Brite, 7th Generation)
CPU: AMD Phenom(tm) II X4 810
GPU: ATI Radeon HD 4200
RAM: 8 GB

I open Firmware 6.61 EBOOT.PBP on JPCSP to extract the files. After the files have been successfully extracted and JPCSP asks for a reboot, I close the emulator and add --reboot to the .bat file:

Code:

"%JAVA_CMD%" -Xmx3072m -Xss100m -XX:ReservedCodeCacheSize=192m -Djava.library.path=lib/windows-amd64 -jar bin/jpcsp.jar %* --reboot

Every time I run --reboot, it always hangs at various points. The closest I got to loading anything was when I was able to enter the Memory Stick. When JPCSP tried to load the thumbnail for Firmware 6.61 EBOOT.PBP, it shows this:

Code:

09:10:45 ERROR compiler - root - Catched exception 'java.lang.NullPointerException' while compiling 0x088A9494 (0x088A9494-0x088A9714)

Also, it seems that certain PSP Models don't load with the --reboot command:

Code:

PSP Model                         | --reboot Status
----------------------------------+----------------
PSP-1000 (Fat)                    | Not working
PSP-2000 (Slim)                   | Not working
PSP-3000 (Brite, 3rd Generation)  | Not working
PSP-3000 (Brite, 4th Generation)  | Not working
PSP-N1000 (GO)                    | Not working
PSP-3000 (Brite, 7th Generation)  | Able to load, hangs at various points
PSP-3000 (Brite, 9th Generation)  | Not working
PSP-E1000 (Street)                | Not working

The power of your computer should be enough: you have enough RAM and your 2.6 GHz CPU is fast enough. That should not be the issue.

When you run the "Firmware 6.61 EBOOT.PBP", it installs only the files that are used by the PSP Model at that time. E.g. if you have defined the model as a PSP-3000, it will only install the files necessary for a PSP-3000.
After that, when rebooting, you cannot change the model any more as the files for the other models are simply missing. The PSP hardware is not supposed to suddenly change on a real PSP ;-).

I must admit that I have not fully tested the LLE implementation for a PSP-3000 model. So, the problems you are reporting are probably related to the PSP-3000 specific emulation. I mainly test using a PSP-1000 model.

Great, you have spotted some functions unimplemented in LLE:

Code:
