Will we receive a notification of when the rebuilt 1.7.1 pack is uploaded?

And my other question please, how do I use the shaders? Because none of them are applying, so I don't know if I'm doing it correctly. I was trying to add a gameboy boarder of the physical gameboy handheld, with the green gamescreen.

I believe the stable builds have been updated less than an hour ago already:
https://buildbot.libretro.com/stable/1.7.1/nintendo/wiiu/

I don't know of any way to get notifications from the buildbot, I only check by entering the site and verifying the hour in which the build was made

But why the new stable build a try, try out PrBoom, it should work properly, if not wait until tomorrow to be sure, but afaik those should be the new stable ones.

Thanks I'll grab the prboom from there. :-)
Btw, do you know anything about the shaders, and how to use them? Or is 1.7.1 still not able to use shaders?

From what I know, shaders should be compatible with the Wii U build already.
However, I do not use neither shaders not overlays, so I don't know how to set them up at the moment.

I believe @cucholix does know, so perhaps he could help you out there

Nope, the shaders have to be compiled with propietary software so we can't bundle them.

Damn, looks like shaders didn't made it for 1.7.1 after all :/
Fair enough, I can deal with it having such beautiful overlays I posted above

Shader support IS there but we can't dristribute the pre-compiled shaders legally

Basically it's the same slang files that are used on windows / linux / android, but there is an extra step that has to be executed on them before they are usable (the compiled shaders are .vsh)

I have a question

I ripped the save of my 3DS VC Pokemon Crystal to use it with the rom on Ganbatte or mGBA. It works on PC, but crashes on WiiU.

Am i doing anything wrong?

How to force mgba to show FPS ?
And is it possible to speedup the game (turn on frameskip with hotkey)?

What are these extra steps?

You need to compile them with glslc, C++ and a wiiu glsl shader compiler

Is there any way to get the app.xml out of each core?

Is it possible for someone to write a guide on how to do this here?

Integer scale is broken on the latest Stable. And when I use custom aspect ratio and load a game it crashes.
Try this for SNES games.

Go to Video options
Aspect ratio to Custom

Aspect Ratio Width 1365
Aspect Ratio X Pos. 278

Aspect Ratio Height 1149
Aspect Ratio Y Pos. 0

Go to Quick Menu
Options
Crop Overscan: Off

This should give you 4:3 Aspect ratio that fills a 1080p screen that matches a CRT for SNES.
Then load a different game and it crashes.

Yupp, I second that shader compilation tutorial. I'd love to use shaders with RetroArch on Wii U.

Osakasan · Feb 20, 2018

I second the tutorial too. I've been looking for a pre-compiled shader pack for Wii U with no success, so i'll be happy to compile them myself

SG854 · Feb 20, 2018

Has anyone tried the aspect ratio thing? I would like to go to a previous version that works but even the 2-10-2018 crashes also.

retroarch Wii U crashes if the arpect ratio/resolution goes above 1080p in horizontal or vertical res. It has been like this forever.

I want to get my Magic NS dongle up and running in Retroarch.. I got it to work with the older Hid to Vpad Enabled build but its too buggy and DSI's way too often

Ah yeah, a friend of mine has one of those fellas to use his Xbox One S Controller on the Switch. Cool stuff!

Oh that really sucks. Is it fixable? When you turn crop overscan off, it cuts it off from the bottom. The only way to fill the screen is to use 1149 for Height, which is higher than 1080, and it should fill the screen perfectly. You'll get full SNES resolution without any being cropped and it will be formatted to 4:3 like a CRT.

I actually got that aspect ratio from this video.

Skip over to 15:46

The Horizontal and vertical position is a bit different on Retroarch. Its 0 for vertical resolution, it should fill the screen by default.
And for Height I took 1920 - 1365 = 555. And Divide by 2 to center it. Which gave me 277.5. I rounded up to 278. This should center the image.

I'll try asking aliaspider and gblues about this, maybe there is something that can be done about it.
