Metal Slug Anthology - Adreno 320 rendering problem

[cv47]

PC

Android with Adreno320 GPU

depthTest issue? As we all know, Adreno GPU driver is pretty ulgy.

Try disabling buffered rendering or mipmapping

Let me know if you still get the black screen above.

[cv47]

There have a better emulator for Metal Slug (series) .

[hrydgard]

That's no reason to close if the problem remains..

[cv47]

Toggle rendering mode to "Read framebuffers to memory (CPU)" everything fine but not playable

[hrydgard]

Why not playable? Too slow?

[cv47]

The speed is not acceptable..
I got full speed (30/30fps) on buffered rendering mode..

[xsacha]

Can you check if the PC is using the same settings?
Maybe your PC is using a similar setting that is too slow for your phone but acceptable speed for PC.
It might just not work under certain conditions.

This game used to work fine in official 0.9.1 and was playable (almost full speed) on buffered rendering on my xperia play with GPU adreno 205.

@raven02 After #3767 was merged into master in 0.9.1-951-gb33f309 Metal Slug Anthology is now broken on buffered rendering and unplayable on android.

This how the game looked from official 0.9.1 to ppsspp-v0.9.1-949-g4e86fc6 (last working build).

This is now how the game looks since ppsspp-v0.9.1-951-gb33f309 (screenshot taken from latest build ppsspp-v0.9.1-1875-g0624f50). As you can see, main menu and ingame graphics are broken.

PS: If you use Read framebuffers to memory (CPU) the menu and ingame graphics are fine, but it's too slow to be playable.

Sorry for my bad english.

@DerinQyu
Thank you for your info..can't wait to test it in official 0.9.1 :)

[hrydgard]

You mean 0.9.5 :)

And it will be the same unless we find a fix before I push the release...

@raven02, wanna have a look, as it seems to have been #3767 ?

[cv47]

@DerinQyu @hrydgard
official 0.9.1 work perfectly (Buffered rendering , Adreno320)

[dbz400]

I think it may be the skip 3 frames has been taken out from this mode and slow down a bit.

[DerinQyu]

Issue update.

Tested devbuild 0.9.1-2122-g36d433c and the black screen in buffered rendering is still there, but now "framebuffers to memory (CPU)" and "framebuffers to memory (GPU)" are broken too just a black screen. Now the game is totally unplayable.

Tested on gpu "Adreno 205" and "PowerVR SGX 531", I don't have a tegra or mali device so I can't test them.

EDIT: Forget what I said about power vr, it is working fine in metal slug 1-5 the only problem is that the emulator hangs when trying to load metal slug 6, btw adreno issue is still there.

[dbz400]

Just wonder buffered rendering works fine now in latest build for this game?

[dbz400]

Just tested in latest build , should be working fine now in buffer rendering mode .

[DerinQyu]

@raven02 Just tested build 0.9.5-312-gd50b01a with default settings and is still showing that black screen on menu and ingame. Tested on my xperia play with gpu adreno 205.

As far as I know this is an adreno issue only.

[DerinQyu]

Tested build 0.9.5-848-g726327b on my xperia play and the menu and ingame still have that black screen on buffered rendering mode.

[xerofdv]

0.9.6.2
still has the issue (regression)
the only time it shows a full [frozen] frame is when you switch from [framebuffers to memory (GPU)] to [buffer rendering mode]

Tested on my xperia play with gpu adreno 205.

[DerinQyu]

Issue update.

Tested the following devbuilds:
0.9.6-639-gb74119c, 0.9.6-654-ga8eb92f
0.9.6-664-g1268bbd, 0.9.6-681-gfb68e1f
0.9.6-689-g432a43f, 0.9.6-691-g4f2f8f0
0.9.6-702-g652008e, 0.9.6-716-g27ae8be
0.9.6-722-gfaf6f95, 0.9.6-736-g35f72df
0.9.6-738-gb25c9a5, 0.9.6-747-g6f38936
0.9.6-749-g341a491, 0.9.6-771-g9bea246
0.9.6-773-g4082186, 0.9.6-778-g1b4cc5e
0.9.6-779-gdacb940.

The regression is still there, blackscreen on both menu and ingame graphics.

Tested in my xperia play with gpu adreno 205 and android 2.3.7

[dbz400]

Retested on my Adreno 320 with default setting (which is buffered rendering) .All look good now

[dbz400]

Please close it then .

[DerinQyu]

Wait don't close it!

What devbuild are you using raven02?

I'm using devbuilds 0.9.8-561-g2b50fcb & 0.9.8-563-g9732a6c and the game doesn't work on buffered rendering, there is still a black screen.

Maybe it is an adreno 205 issue only?

[dbz400]

I also tested 561 and still ok.Are you using android 4.3?

[DerinQyu]

I tested on my xperia play with stock rom android 2.3.4 with an adreno 205 gpu.

[dbz400]

Are there any newer Android version available for xperia play?

[unknownbrackets]

Even if not, there may not be much we can do if this is some driver bug in some old version of Android that is no longer officially supported by the GPU vendor or something...

-[Unknown]

[DerinQyu]

Last official android version for xperia play is 2.3.4 but there are 4.1.1 custom roms the problem is that I'm on a locked bootloader so I'm stuck in gb, anyways game used to work back in the day but with all the great improvements ppsspp has had lately I think it's a reasonable trade if adreno 205 issue can't be fixed.
Good thing I have a backup of 0.9.1

You can close this issue if you want, sorry for the trouble.

[dbz400]

I think unless we can find out which exact build break it since 0.91 though would be very difficult

[DerinQyu]

raven02, all the information about the adreno 205 problem is in my first message on this issue. This was my first post:

Humm unfornaturely i cannot compile Android build .Probably if anyone who can build Android , can help to revert this commit with current master and post a build for you to test on your device.
