Hacking Fixing Nintendont widescreen hacks in some virtual console gamecube injects

RePTiLyK · Aug 15, 2025

So I am using UWUVCI to create some Gamecube virtual console injects for my Wii U, with (arguably) some great results. To enable widescreen I configured the Nintendont config file to "force widescreen" and use "Wii u widescreen". In some particular games, although the widescreen is in effect, there are some serious problems: Wario World, Paper Mario TTYD and Kirby air ride. For example, in Wario World there are some serious clipping effects on the borders of the screen and in Paper Mario there are black bars in the cinematics.

After checking the Nintendont Compatibility List, these problems are already reported, and for Wario World in particularly it states that "Needs Custom Patch to Fix Clipping". After some serious digging though, I am yet to find said custom patch or fix, and I am not certain if it already exists. I have tried the following fixes with no luck:

- Enabling cheats in the Nintendont config file, and using gecko files (.gct) for widescreen fixes of these games in the /codes folder of my Wii U SD card. After some more reading it seems that these codes are already present in Nintendont to enable widescreen, but without fixing the issues.

- Using patched ISO files for the injection, with what I assume is the gecko widescreen fix codes already present in the ISO. For this I used xdelta patches for the ISOs, and was able to create the injections, but without resolving the above issues.

Am I missing something? Is there any way I can play these 3 games flawlessly in widescreen in my Wii U using UWUVCI for the injection?

Any and all feedback is extremely welcomed.

Hi there. Will try that fix, thank you!

Do you happen to have something similar for paper Mario ttys? Or Kirby air ride?

Masana · Aug 16, 2025

You must use these codes, if this does not solve the problem, you must look for others.

paper Mario ttys

Kirby air ride

After trying this fix sadly I have to report I still have the popups in Wario world. I basically applied the xdelta patch, and generated an injectable with UWUVCI. Nintendont settings stayed the same (wii u widescreen and force widescreen). I have also tried those codes for Paper Mario and Kirby, without any luck.

Am I missing something?

I think you need to extract the main.dol file that is in the .iso file

Clipping is a common issue most games suffer from when forced to widescreen. AR codes usually work better, but they're not available for all games. In some cases you just have to pick your poison. Live with 4:3, or deal with minor graphical anomalies.

Dolphin wiki usually has the best 16:9 codes for a game. For example, here is the page for Wario World, find the code in the enhancements section: https://wiki.dolphin-emu.org/index.php?title=Wario_World

Are you talking about patching the main.dol file with the gecko code? I think the patching with the xdelta files is doing that already...

I have already used those codes. Both using them as gecko files and enabliNg cheats in Nintendont, and applying xdelta patches to the iso files that add those codes. None worked.

Has anyone actually played these games as virtual console injects on the Wii U without these issues (texture pop-up on wario world and black bars on paper Mario ttyd)?

Do you force widescreen on the Nintendont settings? Are you using UWUVCI? Which base are you using?

If you could share your settings that would be helpful

Also how did you apply that widescreen code for paper Mario?

Masana · Aug 17, 2025

I don't inject them, but I'm sure it works. I used the latest GX USB loader. The injector's video settings will override Nintendo's. If you get artifacts, your game isn't patched properly. Try changing the ISO and patching it with the software I used. I'll test injecting next week if you can't, but it's a waste of my time.

RePTiLyK · Aug 18, 2025

I may have found the problem. It seems widescreen hacks stack, so having a injected patched ISO with widescreen, and enabling "force widescreen" on Nintendont further increases the "game area", and reintroduces the problems from default Nintendont widescreen hacks. Disabling the force widescreen option and using the patched ISOs let's me play these games in widescreen without artifacts. Enabling the force widescreen option and using non-patched ISOs gives .me the same widescreen "game area" but with artifacts.

Without comparison game pics took me a while to find this widescreen stacking effect. For example, in wario world at the very beginning of the game and not moving, no widescreen hides both the magical hats on the right; widescreen shows me one magical hats; and stacked widescreen shows me both magical hats.

Now it seems I need patched ISO files or gecko files for each game I play to enable widescreen, since relying on the general Nintendont "force widescreen" will cause problems for some of the more difficult to set up games.

Masana · Aug 18, 2025

I recommend you never use this option and some games without codes and hacks are played in 4:3

RePTiLyK · Aug 18, 2025

Adding these games to the list of exclusions for the force widescreen option in Nintendont may be a more elegant solution, albeit requiring compiling. Saves me the trouble of getting widescreen hacks for every game I want.

I am deeply sorry if it sounded like I was complaining or generally ungrateful. That really was not my intention, and may have sounded that way because English is not my main language. I really am extremely grateful to you for your patience and helpfulness, as well as to everyone involved in this community and hacking scene.

In this reply I was just mentally noting what I was going to do, instead of hacking each game individually (and just patching the ones needing particular hacks). Re-reading my post it may sound like I am complaining about these changes not being already implemented, but it really was not my intention!

Masana · Aug 18, 2025

Don't worry, take your time to explore the different ways to play your games in the best conditions. Come back if you need help.

RePTiLyK · Aug 20, 2025

So just a quick update... Ended up adding two lines of code near the end of the PatchWidescreen.c file, so that Paper Mario TTYD and Wario World are ignored by the "forced widescreen" option in Nintendont, and used patched ROMs for the injects. Both are working beautifully. Thanks again Masana!

Hargad · 2026-06-17T22:17:14+0100

Is this clipping issue only when trying to play in widescreen? It doesn't explicitly state that the clipping is when trying to do widescreen in the compatibility list notes.
