Blue screen after first save (UCJS10002 : Doko Demo Issho)

[kedamohno]

Game or games this happens in

UCJS10002 : どこでもいっしょ(Doko Demo Issho)

What area of the game / PPSSPP

After I saved my game for the first time, I can't open the game without a savestate. It has a blue screen every time. (thats very bad since the games whole point is checking on toro everyday :()

heres my savedata:

UCJS10002000.zip

What should happen

It should just open to the screen that asks if you want to continue. I can get to that screen via savestate:

(thats how it looks) But the crash makes it so I can't progress in the game. this crash never happened until I actually saved the game, and there was a continue button.

The game will also crashed not long after running it, if a savedata is present (using the savedata provided in the first post, may be the savedata didn't get fully saved and corrupted?)

thats true, and really interesting! do you think I should try maybe deleting my savestates and trying again?

[sum2012]

@kedamohno Yes,I do think so

[IrfanH495]

I'm not experiencing a blue screen or maybe not yet. I don't understand the time difference here.

after adding to compat ReportSmallMemStick I can load games without problems on Android, I don't know how on other devices

[kedamohno]

thank you all!!!!! I deleted the first save, started a new game, and dont seem to have any issues after i close and open again. i do recall instead of using esc and pressing "exit game" I think i closed the ppsspp tab which was probably a terrible idea and might have corrupted the save. i'm going to wait until tomorrow to see if theres any issues, but I think it might be fixed! :)

[hrydgard]

I went ahead and added it under [ReportSmallMemstick] too.

[IrfanH495]

I don't use last build, it's really random, sometimes the game loads itself, sometimes it won't load .
exit the application and enter it again while the game loads itself.
I will try last build.

[IrfanH495]

@hrydgard sorry, I think my suggestion is wrong.
in the last build it looks like this.

at the end of the video the game loads as usual

[hrydgard]

well, that setting usually doesn't really hurt anyway, so i'll keep it.

[kedamohno]

sad update... i checked on toro last night and he was fine, but now its crashed again. im not sure what to do to keep the file from corrupting? :(

[kedamohno]

also im not sure what a reportsmallmemstick is. is there something i should download?

[IrfanH495]

@kedamohno Are you stuck again where the characters are not visible in the room?
you left him he seems quite long read this

Just like your save data above, I also experience it but it doesn't become a blue screen.
this game follows our time in the real world I tried changing the time to 1 pm and in the game to noon

[hrydgard]

also im not sure what a reportsmallmemstick is. is there something i should download?

No, it's a per-game compatibility setting. I've set it on now for all future versions. It tricks games that your memory stick is smaller than available disk space, because some games can't handle modern disk sizes...

[IrfanH495]

I didn't mean to spam
@kedamohno I tried save data above, and found the pet had gone and left a letter
Goodbye•••
I go on a journey to find a way to become human...
I wanted to talk more...
https://youtu.be/_QGvog9p5s8?si=bqn03aj5MEZ2abFf
so I guess the game crashes after the pet leaves or is this a different issue

[kedamohno]

@IrfanH495 I do believe thats a game feature if you leave him alone too long. maybe thats because the save youre using is mine from a while ago...hopefully that shouldn't be an issue for me, my time seems to be synced correctly! I tried the save again, im deleting my old save, my savestates, and trying again fully! if it crashed tomorrow, i'll have to keep investigating :,)

oh, i see! thank you! i'll make sure to check whether i have that on or off...

Changing CPU clock to 55 seems to works for me, so there might be timing issue here instead of corrupted savedata.

I'm able to run the game with savedata present

PS: the thread that crashed is probably audio-related thread since it use "pcm" (ie. "sgx-pcm-th") in the thread name, and the last file being loaded before the crash is 5=sceIoOpen(disc0:/PSP_GAME/USRDIR/data/sound/bgm/hiru1.sgd, 1, 0)

Edit: This could also be timing issue with sceUtilitySavedataInitStart/sceUtilitySavedataShutdownStart dialog, just like the msg dialog at #15304 where changing the CPU clock could prevent a crash.

Edit2: based on the logs the status being retrieved by the game seems to be missing the 4 status (ie. 3 -> 0, instead of 3 -> 4 -> 0), so this could also be similar issue to #15068 (comment) (but since i've lost all my partitions due to bad sector, so i can't test whether that fix worked for this game too or not)

[sum2012]

@anr2me Maybe we need a compat setting for the status.

[sum2012]

@anr2me Change timing setting to Simulate UMD slow reading speed work !!!

im sorry, i still new to emulators so im confused. is there anything i should edit in ppsspp settings? do i need to edit the files in ppsspp or do something to my computer? I still feel like I have no clue how to prevent this crash :(

@sum2012 i think you forgot to write the solution :)
Btw, i tried using Simulate UMD slow reading on this game, but it still crashed

@kedamohno the solution (workaround) is by changing the CPU clock to 55 or 111 or 333 from Settings
-> System -> Change emulated PSP's CPU clock

[sum2012]

@anr2me I have attach image to Email but don't work here. Anyway v1.16.6-341-g4d7f00f96 have merged Simulate UMD slow reading. I test it also load the first post of save in android no problem
