Description

Game Name?

Gradius 2
Parodius: Tako wa Chikyuu wo Sukuu
Penguin Adventure: Yume Tairiku Adventure

Game ID? (right click the game in the game list, properties, info tab)

XANJJ8
XAKJJ8
XAHJJ8
It should affect other MSX VC titles too.

MD5 Hash? (right click the game in the game list, properties, info tab, MD5 Hash: Compute)

[Put MD5 Hash here]

What's the problem? Describe what went wrong.

MSX Titles seems to have some kind of performance issue in Dolphin that causes graphical issues in some parts of the games (missing frames?). It is difficult to explain it without footage, so I'll link to recordings of the games running in Dolphin with an explanation below.
This shouldn't a problem with the MSX VC in a Wii, since this don't happen in an actual Wii console.

What steps will reproduce the problem?

Install and then run a MSX Virtual Console title.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Dolphin 5.0-8716

Is the issue present in the latest stable version?

Yes, Dolphin 5.0.

What are your PC specifications? (CPU, GPU, Operating System, more)

Intel Core i3-4160 @3.60 GHz
Intel HD Graphics 4400
Windows 8.1 x64

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

Here are some recordings that I made of the three titles, but this probably happens with other MSX VC titles-

-Gradius 2 and Parodius Intro:

Problems with the graphics and text can be observed in the Intro of both games, in the case of Parodius in the last part of the Intro, the last member isn't showed at all.
-Gradius 2 Intro can be compared to it running in an actual Wii console with this video:

-Yume Tairiku Adventure (Penguin Adventure):

The graphic of arrow in the shop gets stuck when moving to some items manually (but you can still select them) and the slot machine fish counter doesn't changes until you select a quantity (it should show you how many you put in there), at the end of the level the animation of Penta resting shouldn't be static and Penta isn't showed in the map in early stages in later ones it is showed but some animations aren't showed in that cases for example.
I don't have footage of this game running in a Wii at the moment, but I can confirm that the issues on this game aren't present in a real Wii console.

History

Have you tried setting the texture cache to safe?

#2 Updated by Clector 5 months ago

That worked, thank you and sorry for not checking that.
Can I request a GameINI for MSX VC titles?
MSX VC Title needs "SafeTextureCacheColorSamples = 0", because the middle option apparently still causes some problems at times.

Sure, I'll take care of it in the next game INI update.

I'm surprised we hadn't done this earlier tbh. Thanks for the report, this is a nice fix to have.
