Animal Crossing Wild World Local Play Communication Error

[BannerBomb]

Your console: O3DS

Launch Method: My CFW: Luma3DS v10.1.3 System Firmware: 11.13.0-45U

Launch Method: TWiLight Menu++ v15.3.0 (nds-bootstrap v0.35.1) from a 32GB SDHC card. Version used: Release

Game tested/used/applicable: Animal Crossing Wild World [ADME01]

Expected Behavior: It was expected to not disconnect from the local connection.

Actual Behavior: As soon as the player successfully arrives on the other players island (both players are using TWiLightMenu++ with the exact same information I have listed in this issue) via Local Play (DS to DS) the connection disconnects and the game shows the error "Communication has ended and the game will reset. You may lose progress from the last save."

Steps to reproduce

1. Start the game on 2 separate consoles.
2. On one console talk to cooper and tell him you want to Invite visitors via DS to DS.
3. On the second console talk to cooper and tell him you want to go somewhere via DS to DS and confirm the island is locates.
4. Let the game do the rest.

• By this point you should notice both consoles are connected as the signal strength indicator won't be red with 0 bars anymore.

5. On console 1 you will see the player arrive at the island while on console 2 you will see the player starting to departure.

• After a few seconds both consoles will receive the error "Communication has ended and the game will reset. You may lose progress from the last save." and the player is forced to restart the game which can be done by pressing A or tapping the touchscreen.

[SleepyLark]

Already a known issue (#869), however your issue is more detailed then the previous one.

[BannerBomb]

I'm not sure if this helps or anything. But I have found that right after you begin to departure to visit Player 1's island right when Player 1's (the player waiting for Player 2 to join them) Nintendo begins to fade to black you can press the home button on both Nintendo's and wait on the prompt that asks if you want to close the software for at least 5 seconds then press B to cancel you will notice Player 2 has successfully arrived on Player 1's island and is standing right in front of the gate. Of course it will disconnect a second later with the communication has ended error. I just found this to be interesting how the connection wasn't ended when on the software close prompt but did right after canceling it.

@SleepyLark Ok, I was able to get player 2 to successfully join my island and they were able to freely walk around but as soon as player 1 (the host) left the station the communication error showed up again and when I exited the building player 1 was invisible on player 2's console but it still showed an invisible object pushing player 2 because they were in the way.

Another fellow AC Wild World player here. I have a DSi and DSiXL. Been following development here. Had some success with Multiplayer around April with nds-bootstrap v0.32.1 but stability went downhill after that release.

The last few releases crash to Resetti right after joining another village no matter what knobs I try.

When it worked, I also Tried with DSiXL host with similar behavior, was able to connect, save, visit a house, but got Resetti when out of the village on both sessions. Captured NDSBTSRP if that's helpful

[tricky-pitfall-seed]

Made an account just to post this so I hope I'm doing this right, I was also playing twi to twi and was getting resetti as soon as the connection started, fixed it by, in both DS' twi menu settings, setting "Card read DMA" to off under games and app settings

[RocketRobz]

Card Read DMA has been improved since, and should no longer cause communication errors.

[RocketRobz]

Has been recently reported that the issue still occurs.

[OsmarBros]

This issue doesn’t happens in 0.64.0 at least for me

[RocketRobz]

Then it's safe to assume it's indeed fixed.

I've only signed up because of this problem. I've been despairing of the problem for days now and it's slowly but surely driving me insane, because .. I've tried almost everything I could find about this problem- absolutely nothing has helped so far.

I'll try to give as many details as I can, that this problem will hopefully one day be really solved. The reason I'm posting this is because I've just given up now and don't have the strength to try anymore. It really amazes me how it can work again for all the other people who reported the problem. I just hope that the problem will be taken care of again- I am willing to actively try out all possible solutions if anyone has any ideas or suggestions. The game means so much to me and my friend, it would be so awesome if we could play it together again.

I've opened a new issue https://github.com/DS-Homebrew/nds-bootstrap/issues/1592, so this issue here will be hopefully reopened.
