I found dreamcast games do not work on 5.27-dev with either reicast or flycast. 5.26 stable is ok with dreamcast.

Is there a fix for dreamcast under 5.27? Launch error is as follows:

Aug 29 15:45:21 batocera user.err kernel: [ 215.943654] Alignment trap: not handling instruction f4432add at [<b1762504>] Aug 29 15:45:21 batocera user.alert kernel: [ 215.943660] 8<--- cut here --- Aug 29 15:45:21 batocera user.alert kernel: [ 215.943694] Unhandled fault: alignment exception (0xa21) at 0x8b716144 Aug 29 15:45:21 batocera user.alert kernel: [ 215.943726] pgd = 409abad1 Aug 29 15:45:21 batocera user.alert kernel: [ 215.943743] [8b716144] *pgd=0e7e8003, *pmd=f3152003

domb84 , salut j’ai eu exactement le même problème même sur la dernière bêta du 6 septembre ! Pour résoudre se problème il faut faire une installation propre de la dernière bêta !
