PSP SCUMMVM port for PSPonPS4

[jacobsson]

Ok we're almost there, thank you for your patience

 

[shellters-bob]

Ок!

 

[jacobsson]

Ok so here are the deliveries needed to make your own scummvm 2.5.1 autoboot games, zip includes:

• New fixed scummvm_2.5.1-psponps4 build (psp game folder style)
• A fixed psp-folder-to-iso bat-script
  
• ps4-fpkg scummvm config file
• PSP eboot.pbp to bin extractor (useful if you decide to make your own build from source)

Download here

Instructions
You'll then need to:
1. Replace the content of PSP_GAME/SYSDIR/game with your game files

2. Edit your PSP_GAME/SYSDIR/scummvm.ini to match your game id and game engine, you can find them here.
Note: if you like the original aspect ratio of games change aspect_ratio=false to aspect_ratio=true

3. Convert your folder into an ISO by dropping the scummvm-folder onto the create_PSPiso_from_folder.bat from the download (originally from JMD-PSP-Tools)

4. Use PSP-FPKG to make yourself PS4 scummvm fpkg by choosing your created ISO and the config file in the download

Jacobsson - it works, but with some games it falls out into error. starts working, and in error. We still have to try.

So your iso is working in ppsspp but not on PS4? What game did you try?

 

[shellters-bob]

Yes, the example of the Red Comrades 1: Save the Galaxy, Toonstruck (the file toon.dat must be placed in a folder), But I think we should try again. I'm going to test it today.
PS - your build Beneath a Steel Sky runs perfectly on ps4

By the way, if you want a nice template for the ICON0.PNG cover you can use this one (made by @Vika23 , modified by me):

Jacobsson - thanks!!

if you make an image via PSP-FPKG_v1.0.1 - games slow down, sound problems (glitches)
The Legend of Kyrandia Hand of Fate - sound glitches
The Legend of Kyrandia - sound glitches, slow
Dráscula The Vampire Strikes Back - slow, sound glitches
Might and Magic Clouds of Xeen - very slow, sound glitches, problems with graphics
Maniac Mansion (rus version) - problems with the choice of character actions (not highlighted)
Toonstruck - error running game: Game data not found (everything starts up on ppsspp without any problems!)
And now!
all these games work without problems if you run them - "pspfpkg-scummvm-template" build, Toonstruck - but he writes anyway... it is necessary to look at the ini file.

Yeah, it sounds like the ps4-fpkg-config file "config-title.txt" doesn't take effect in your first examples, it has a lot of improvements to performance, namely these lines:

--bend-30hz-lock=0
--force-dsf-present=1
--optimize-fb-self-resolves=true

I'm also thinking if the eboot of the emu needs to be overwritten (as included in the template)

 

[shellters-bob]

it makes no sense to do it through PSP-FPKG_v1.0.1
pspfpkg-scummvm-template - Everything is here!

I will continue the tests, I will write how and what.

You're right about that!
What tool do you use for building the fpkg?
I'd gladly update our HOWTO guide

 

[shellters-bob]

Standart - gengp4_app, orbis-pub-gen, orbis-pub-sfo

Standart - gengp4_app, orbis-pub-gen, orbis-pub-sfo

Yeah, I started of using those tools manually, but I thought it was too cumbersome.
For simplicity, what if you:
1. used psp-fpkg and tick the box "Pause before creating pkg (debug)"
2. Wait for the build folder to show up
3. Empty the folder and put the template-files inside of it
4. Click continue

 

[shellters-bob]

aaaaa!!!!! OK!!! Thanks!!!

Any ideas why Broken Sword 2.5 The Return of the Templars is not working with 2.5.1 (Shows no supported engine is present. Same on PPSSPP. I did edited scummvm.ini with engine/scumm id)? According to ScummWiki it should be supported since v1.8.0. And the game files are directly available from SCUMM website.

EDIT: I just checked and the game is recognized by actual Scummvm 2.5.1 release for PC
EDIT1: Curse of the Monkey Island doesn't load certain files so just stops at console of ScummVM. Created ISO works in PPSSPP.
Broken Sword 2 has animation skipping/sticking problem, noticed in intro cutscene and while playing in first room with config above.

Zak McKracken and the Alien Mindbenders FM TOWNS - very slow on PS4, PPSSPP - best!
Lands of Lore The Throne of Chaos - writes a missing file "GER\General.pak" on PS4, PPSSPP - best!
The Legend of Kyrandia: Malcolm's Revenge - everything is fine, but on some screens, when switching to another location, the PS4 falls out into an error PPSSPP - perfect!
Toonstruck - what I just didn't do, it doesn't start, it always writes - error running game: Game data not found. I removed the autoboot - I choose from the menu myself - the same error. and the addgame selection does not work (the gray folder does not allow you to select), select work on PPSSPP - but he writes that the game is not supported.

Interesting, PPSSPP seem to solve a lot of stuff under the hood.
For Scummvm on PS4 need to:
A) Set resource path set in the ini as "extrapath=disc0:/PSP_GAME/SYSDIR/game/RESOURCE", or
B) Move all files from the RESOURCE folder up into the game folder

Unfortunately the emu crashes after this selection
