Link battles cannot start during the VS screen

Description

Using the mgba multiplayer feature, I tested with colloseum single and double battles.

I noticed the small flickering during the VS screen, maybe there's something that is not correctly loaded ?

If this can be of any help, I wanted to further investigate on this and tested this on my repo with an old branch, that was last synced with expansion around 7 months ago (last merged PR commit is #4462 ) and a quick link-single-battle worked correctly.

I tried to play around with DebugPrintfLevel in single battles to find where things go wrong, and I found that the host gets stuck in the second iteration of DoBattleIntro (it loops through BATTLE_INTRO_STATE_GET_MON_DATA and BATTLE_INTRO_STATE_LOOP_BATTLER_DATA, but does not reach BATTLE_INTRO_STATE_PREPARE_BG_SLIDE). At this stage, the connected player does not reach DoBattleIntro.
