Do this is also due to corrupted .iso file ?
Because when i download it's says 9MB download, but when unpacked it was 120MB

[t3rr41n]

Can you give me links to download site
When i download the .iso file, i download it from my usual download site
Anyway, do there was a new version of PPSSPP ?

Btw, are you using Frameskipping?
As i remembered there is a game that shows blackscreen when using frameskipping, not sure whether it have been fixed on the latest dev build or not.

Edit: probably unrelated

I used frameskip for this game and it's working fine.

[t3rr41n]

Already reinstall the PPSSPP, issue still persists
Already download another .cso of the game, issue still persists
Maybe i will try the latest git build

[ghost]

@t3rr41n can you upload the screen recording of the issue?

[ghost]

Do not use cso format.

Maybe i will try the latest git build

Yes try the ppsspp buildbot.

@t3rr41n what is your device are you using?

[ghost]

@t3rr41n what is your device are you using?

He already stated that his phone is Redmi 2 Pro Android Lollipop.

[Panderner]

Hmm ancient snapdragon phone. Can you produce GE Dump?

[ghost]

@t3rr41n no feedback/outdated.

[Panderner]

Do not use cso format.

I played this game using CSO format working fine.

[unknownbrackets]

https://report.ppsspp.org/game/NPEZ00002_1.01

Hm, not many reports. CSO ought to be completely fine for this or any other game (I personally run every game using CSO.)

It's possible this is depth clamp or dual source alpha related. A GE frame dump would indeed be helpful.

See here for instructions - it's not hard and works on Android too:

You can zip that and then drag and drop it into a reply here.

Sorry, last week's was crazy busy. Here the GE Dump https://drive.google.com/file/d/1F3J7PdEAMvGEF3DB54oVmbWNyQNqGXaQ/view?usp=drivesdk

In the past, black screen issue can be solved by extracting the content of the ISO based on this PPSSPP video (not sure whether the issue has been reported in the past or not tho) https://www.youtube.com/watch?v=Gjq7jKMMMvE

But based on your video, seems to be flickering issue instead of black screen.
Btw, have you tried changing the Buffered rendering Mode settings?

@anr2me You don't need to extract the content of the ISO it's working fine.

[Panderner]

@t3rr41n Check the CRC if the game is same as a working CRC.

I use buffered rendering and simulate block transfer. Also the buffered rendering set on natural color, but with both options turned off the issue still persists.

How i check the CRC of the game and the real one ?

Right, when i test the ISO (decrypt) everything fine. No corrupted file, etc.

@t3rr41n Long press the game and then press calculate CRC.

Well based on that video on youtube the ISO didn't have any issue being extracted with another app too, but it looked like PPSSPP seems to fails to load some of the files from the ISO (or may be failed to extract it?), thus running the game from extracted ISO worked for that PPSSPP version.

However, that video was an old version (1.9.4) of PPSSPP, not sure whether it has been reported before or already fixed by now tho.

@anr2me thanks for the yt link got the idea and play Resistance Retribution without freeze hahaha 🤣

Scroll down to see calculate CRC.

Scroll down to see calculate CRC.

yeah, the list of options has gotten too long for some screens... I think we might need to add an indicator of some sorts that there are more items

[t3rr41n]

Sorry, a little off topic.

I have a Final Fantasy Type 0, but some cutscenes won't play. When i read the translation website, the website state that this is because the limitations of the UMD system on the PSP to read only 2GB max and recommend to install CFW on the PSP. (Since the game combine two UMD disk)

I want to ask, do PPSSPP support reading all game file above 2GB (like on the CFW). Or there any limit PSP can load all files ?

Thanks

[ghost]

@t3rr41n use ppsspp v1.12 https://www.ppsspp.org/downloads.html

[hrydgard]

@t3rr41n I think we resolved all those limits quite a while ago, specifically for FF Type 0. But if you're having issues with it, please create a new issue report here instead of posting in an unrelated one.

Okay, anyway thanks @hrydgard

[ghost]

I think this issue can only reproduce on adreno 306 GPU

[t3rr41n]

I will try on another device, and see if the issue still persists

Make sure are you using default settings.

[ghost]

I try this also on android 6.0 Mali-400 gpu the game works fine.

[unknownbrackets]

Okay, so to recap what we know:

• It's not working on a Adreno 306 device.
• It's happening with a good copy of the disc.
• It's working on older Mali 4xx devices.
• The most interesting thing it does in rendering seems to be a Z scale/offset of 0, which is pretty uncommon and possibly even a (harmless on the PSP) mistake in the game.

[t3rr41n]

Already try on another device, the game works fine. So i think the errors occurs only on my device (adreno 306).

[t3rr41n]

Looks like there were an error on adreno 306 rendering of the game graphics.

[Panderner]

@t3rr41n what another device are you using?

[ghost]

Adreno 3xx series is very problematic on ppsspp
See #13542 and #11732

[ghost]

@t3rr41n can still reproduce this issue?

[t3rr41n]

Yes, it seems that it was really a Adreno 3xx series issue. Already tried on non-Adreno device it's run properly

[ghost]

Here's the screen recording for a clearer idea of the problem https://drive.google.com/file/d/1FCmOpoJ4YUroK5Mrx6Aaju82BrlMpsWT/view?usp=drivesdk

I will try to reproduce this on my vivo y51a adreno 306.

I cannot reproduce this issue of yours @t3rr41n using the latest build 🤔

[Panderner]

hmm it seems the vivo y51a and Redmi 2 Pro are using a same GPU.

[unknownbrackets]

It's possible the change I made for drawing/clearing recently may have improved this.

[ghost]

t3rr41n no feedback?

[t3rr41n]

Okay, i will try it again using the latest build

How about now?

[t3rr41n]

Looks like the issue was solved in the latest release

Great, thanks for the feedback. Going to close this then.
