Chds do not open properly

[SsssQ]

When i found some redump format gdroms(puyo puyo fever, dream passport 3, etc.) i wanted to convert them to chd with chdman. After transferring to my rpi3b+ they did not open properly (empty Dreamcast dashboard or even core crashing on rom). Help

@ssssq
So why did you think the Problem lies with you Recalbox ?
Did it worked before ?
If yes maybe now it's a Problem with your Files or CHDMAN

If you didn't know, the CHDMAN Help can be find here:
