[TheTechnician27]

Describe the Bug

Issue reported on the Discord by defunct32.

Reproduction Steps

Appears to happen constantly throughout the games, and it can be reproduced right after a battle.

Can you post a save state right before the problem? I loaded your memory card save and won a battle but can't reproduce the problem. May be you will also want to add a little tutorial on how to reproduce the bug from the attached memory card.

Hi, prafull. I unfortunately am not the one who encountered this issue. I do not currently own, nor have I ever played, Arc the Lad. While I believe I was reasonably thorough in gathering information about this issue, it's not something I have the means to try to reproduce.

The GS dumps and memory card come from a user who does own the game.

It seems to happen in transitions, when the game unloads a scene or map and loads a new one. The fastest way to reproduce the issue is right at the beginning of the game, after the book cutscene.

a savestate just before it happens (next to a transition) would be really helpful

Sorry for the ultra late response. Here is a screenshot (just press X to advance): SLUS-21165 (E69E7F58).01.zip

Here's also a gs dump: Arc the Lad EOD - Transitions bug.zip

Also, hardware mode still seems to have some glitched transparent effect covering some cutscenes, but only at some angles. This could be seen at the initial beach cutscene.
