saved state problem

[brito9112]

Hi community, i using PSP 1.6.3 on windows 10, Ubuntu 18.04 and Android 7. The game i´m testing is "kidou_senshi_gundam_-_gundam_vs_gundam_next_plus_japan".


When i copy my save state from windows or android to the other platforms the saved state works great. But a saved state created on Ubuntu 18.04 appears corrupt on the other 2 platforms, the strange is this "apparently" weird saved states works great on Ubuntu 18.04.


Before i copy the files i check permissions on my user on Ubuntu 18.04 and this have "rwx" for this folder.


I activate the debug mode on Windows and Android but i cant find any debug file. ¿where this files are located?

Please forgive my English, is not my native language.

PD: Remember, always attack ideas, never people.

Can you try using the latest git build on each one? Just in case there's a slight difference in version.

Is it only happening with this game, or does it happen with other games too?

One thing that would really help is if you edit ppsspp.ini (on Linux, it's in ~/.config/ppsspp/PSP/SYSTEM/, on Windows it's in the same folder as the exe /memstick/PSP/SYSTEM, or My Documents/PSP/SYSTEM) and find this:

AutoRun = True

Then change it to:

AutoRun = False

Now, load the game and it will start out trapped by the debugger. Go to the menu and create a save state now - then attach each save state here. In theory, the two save state files should be nearly identical (there'll be a timestamp in them so not 100% identical.) If the Linux save state doesn't load on Windows, I should be able to figure out the difference.

If that one works, but a later one doesn't, then it'd help to try to create a save state near the same spot (maybe right after loading an in-game save) that has the problem. There will be more differences in this, because it's inevitable that you'll take a fraction of a second longer somewhere to make the save state, but we might still be able to figure it out from that.

Hopefully the issue is just that the Ubuntu version is using a newer build, though.

Hi, this attachment is the output on the Debug console using gundam game, in this moment i was using W7 as base OS, the save of the error was made on Ubuntu 18.04. Latter i will publish the links to the save state that you ask. I only have 2 games. Dante's Inferno and Gundam. The save state problem is present on both of them.

I make the 2 saved states and they are here mega.nz/#F!zBojHQob!xGh4I7Nir_XFHYS_2A_dAA. Both are close to the same time no matter the moment when you create the save, the games (Gundam and Dante's Inferno) still crash, you can find the game in coolrom.com/roms/psp/45604/Kidou_Senshi_Gundam_-_Gundam_vs._Gundam_NEXT_PLUS_(Japan).php

Sorry, I don't own the game so I can't download it.

But, I did take a look at the state file. The Linux save state appears to be from a newer version of PPSSPP than v1.6.3, and the windows version is just v1.6.3.

It should fix it to use the latest git build on both devices. Save states can't go backwards, older versions aren't compatible (e.g. latest git linux save states cannot be loaded by v1.6.3 Windows.)

i just download both versions from the project web page. This means that i have to compile my own version of the program on windows?

[LunaMoo]

You can, but there's no need, just move down on the download page where you can find buildbot or enter the buildbot site directly. It has automated builds for android and windows as those are primary platforms of PPSSPP, just pick whichever you need.

[brito9112]

Tanks for the link, but i have another question now, what package of ffmpeg do i have to install on ubuntu to compile successfully the program?

This last question is because i have now a lower version on my ubuntu machine, and the link that you gave me not have the linux build.

[[Unknown]]

It comes with ffmpeg in the ffmpeg/ subdirectory which is the right version.

It must not be libav, and must be FFmpeg. FFmpeg and libav often change their API in subtle ways, so if you use a different version you may get crashes, glitched videos/music, or missing videos/music. We compile against FFmpeg 3.0.2 currently.

I'd strongly suggest statically linking with the ffmpeg/ subdirectory version.

Thanks for your time

Ah, that means you didn't clone with --recursive. You can go into the /home/jose/alex/ppsspp-master folder and use git submodule update.

Basically, we use libraries and code that other people have written. If you clone our repo or download the zip from GitHub, that ONLY contains ppsspp's code. It doesn't contain ffmpeg, armips, glslang, etc.

Also make sure you've run:

sudo apt-get install build-essential

This should give you pthreads.

Unfortunately using Git is imposible for me, is posible to download a zip ready to compile?
