Hacking Possible to Disable the Wii's (De)Flicker Filter?

[NoobletCheese]

I also checked some wiiware stuff (bomberman blast, castlevania rebirth), but they didnt had the filter (2C 03 00 00 41 .... 41 82 00 40)

They should if you uncompressed the 01.app. It's in N64 games and Bomberman 94.

But its hard for me to notice a difference, so I wanted to ask if wii vc uses filtering.

I think most of them do not use it, but may if Wii is set to 480i. Check in Dolphin by toggling 'disable copy filter' while the game is running.

(Sometimes I use a jp "sneek nand", so I cant use usbloader gx in that case)

That's a shame as ULGX will work for compressed wads.

So you could use the gecko cheat code method, or edit 01.app and repack it.

So using these cheats we can disable the vfilter and dithering?

vfilter only so far.

GX should still work, no?

I have a wiiu and use only sneek not neek2o
I also dont like the idea of installing an wad twice just to show it in the list for usbloader gx

Also booting sneek is quite fast with the wiiu, it takes <1 min to boot jp sneek nand

@NoobletCheese
Thanks completely forgot the dol can be compressed, but uncompression and compression of the archive can be done via gblzss so I can easily convert my wads

I've been able to boot any region emunand in <5 seconds on the regular Wii, but the nands don't have a ton of content on them so that could make a big difference

 

[godreborn]

indeed, the amount of time neek takes to load is dependent on how much content is installed on it. that's one reason you should only put games that need it on it. I only have two games on mine on the wii u. I don't go into the home menu on neek very often, almost always just boot the game from within usb loader gx. the only thing I don't like is that it reloads the wii u upon exit unlike normal emunand, which reloads usb loader gx if it's set up that way. I think Cyan said it might be possible to get around that issue, but I don't know much about it.

do you mean sneek/neek2o with emunand or launching stuff via wiiflow/usbloader gx emunand feature

the step which takes longest is probably the Waiting for ARM to reset ppc screen, also showing the actual menu after pressing "A" on the health screen takes some amount (but with a lot of channels installed, only 1 or 2 spaces left)

usbloader gx cant boot sneek stuff straight, it only starts the system menu

 

[RodriGames40]

So using these cheats we can disable the vfilter and dithering?

Yes, you shouldn't need this if you're using the latest USLX, because the deflicker patches are already built-in. This is meant for old loaders with no support anymore, like the one I use to run DVD backups directly from a external drive.

All games are supposedly affected, there's vfilter strings in every single one of the games i've modded, epilepsy/darkening filters included, that can also be disabled. You should patch all games except the N64 ones, because the deflicker filter is already disabled in these when using progressive scan, you still need to disable the epilepsy filters though.

@RodriGames40 Like @NoobletCheese mentioned, the cheat will only disable the filter. Dithering would require a separate patch.

The loader doesn't have an option to disable dithering, mainly because it tends to make things look worse. But I did add filter strength options, since that does help to clean up games like RE4 where a weak filter might look better than no filter.

The cheat is basically the loaders "OFF (Extended)" setting, so it does break fade and brightness effects in some games. And you might not notice if somethings broken until you're a few hours into a game.

I think booting directly into a game is a neek2o feature within the loader. But even if the loader could boot directly into a game with sneek it wouldn't be able to apply cheats anyway.

I'd like to try sneek/neek2o myself so that I could make some improvements, but I've never been able to get either to work on my Wii. And after trying every suggested fix out there I can only assume that there's a compatibility issue with either my SD card, USB HDD or my launch console with BootMii as boot2.

I know this isn’t a Wii U thread, but I am wondering if this is possible to be done on a Wii U using Wii VC injects. Would editing the hex file on the ISO itself before injecting work?

I never said dithering could be disabled with it though, only deflicker patches. And it's better this way, disabling it causes some serious color banding issues, so just assume you're playing a PS1 game and that's it.

@RodriGames40 The person asking said "So using these cheats we can disable the vfilter and dithering?" and you replied "Yes". So I just wanted to make it clear that it does disable the filter, but not any dithering.

Anyway, the option doesn't even exists in USLX so he would've figured it out quickly, and it's not like we recommend disabling that as well. Thanks for the correction regardless.

Hey everyone, I'm new here. Just wanted to say that've found this thread yesterday and tried the method on my copy of Twilight Princess for the Wii and I must say that it looks like 1000x better now. Since I haven't found a tool that would patch the main.dol automatically, so I've decided to create one myself. Since I'm new I can't post a direct link to the github right now but my username on there is EnterpriseFreak-v2 and the project is called No-AA-Patcher. I've also attached an image that shows the huge difference patching the video mode makes for Twilight Princess.

I only bother with sneek becuase of Japanese Arcade Games and Neo Geo Games. I encountered some issues with neo geo stuff form emunand (black screen/not booting) so I decided to use sneek for these games (just to add it here, not really relevant, if someone wants to use sneek with vWii/WiiU use this source https://github.com/eluancm/sneek not the one from JoostinOnline https://sourceforge.net/p/sneek/code/HEAD/tree/trunk/)

Somewhere in this thread is a shitty phyton script which does a similiar thing (but of course your way of compiling a proper binary is much preferable, especially for windows). Just one note, you dont have to necessarily repack the iso as e.g. usbloader gx can use an alternate dol

Thanks for the info! I will update the readme to mention that you can just use the alternate dol feature of usb loaders. Should save a lot of time and write cycles!

this (shitty python script/quickly cobbled together form various other stuff I've laying around) can be used to disable gxsetcopyfilter for wiiware and wii vc without manually unpacking/repacking/patching, unfortunately it probably only works with linux (and maybe cygwin/msys2), as it needs python and it needs compiled binaries (which I wont include because wadpacker/wadunpacker needs common-key)

Why don't you just bundle the common-key? Afaik Dolphin bundles it just like NUS Packer and probably other programs too.

Although for USB Loader GX it's a little redundant now since that can already remove the filter for Wii, WiiWare and VC games.

My version of the loader was originally a mod, but it's recently been made official.

Wait, I'm using your version of USB Loader GX and I still get that blury mess unless I manually patch the main.dol of the game... Do I have to enable some special option for it to patch the video mode? Forcing PAL / NTSC 480p still gets me exactly the same quality as the unpatched half of the image that I posted earlier.

 

[blackb0x]

@EnterpriseFreak It's called the deflicker filter. Set it to "Safe (OFF)" and it'll work.
