Other notes

This issue does not happen on the title screen or when playing FMV cutscenes.

Try updating nds-bootstrap to v0.54.1, and see if that fixes the flickering.

Nope, Updated both twilight menu and nds-bootstrap and nothing's changed. as soon as the first FMV and the in-game cutscene ends, the game starts to flicker like hell.

Try changing the ARM9 CPU Speed option then. If TWL speed is causing the issue, try reverting to NTR.

Did that too, but it doesn't seem to affect anything, the flickering still happens.

Just tried it myself in 0.54.2 with Decepticons (USA rev 1). I wouldn't describe it as "constantly," but it's definitely noticeable (primarily while driving through the city area, haven't been anywhere else yet). It doesn't seem to occur at all on the real game card. It does occur on flashcard (with regular nds-bootstrap, B4DS, & EOS) more than nds-bootstrap via DSi SD.
