Game tested/used/applicable

Dragon Quest VI

Expected Behavior

Game running normally

Actual Behavior

When there is a transition (black screen ) if you are entering/finishing a battle, using teleport or using lorelei's harp. The screen freezes while the audio is still running. Reset is needed if you want to keep playing, and the progress is lost. I think it also happened when I was entering a town or a building. Once, the game froze when I was saving the game in the church.

Steps to reproduce

Using Lorelei's harp, the teleport spell or entering battles.

What's the checksum of the ROM file? Did you apply any cheats?

I started playing this game in 2021 when I was using the original kernel on my R4 flashcard. I used cheats once back then. I got back into the game with Twilight Menu installed on my flashcard.

The fastest and easiest way to replicate the bug is by using the teleport spell in loop until the screen freezes

[eku]

using the teleport spell in loop until the screen freezes

Why does one want to do this? Are you sure the official cartridge hasn't the problem?

[huanantonioo]

It’s because it doesn’t happen every time I use the teleport spell, not because it only happens when I do it in a loop...

[huanantonioo]

Update: I tried another flashcard using the original kernel, and it's been working well with no crashes so far

[RocketRobz]

The issue is possibly caused by card read DMA, which is no longer used on flashcards for most games.
Try updating, and see if the issue persists.

Hello, I tried updating to the latest release and still freezing with a black screen (I'm using the teleport several times because is the fastest way to replicate the bug but it also happens when the battles start)
