Also i have 3 dreamcasts for Testing there:
-Dreamcast Va1 PAL with G1ATA with noctua Mod and PicoPSU
-Dreamcast Va0 JP with GDAta
-Dreamcast Va0 JP with dcdigital HW2, Fan Mod and Pico 130 Watt PSU

Is there something i could Test?

Thank you, Freudi93, and you've got an impressive list of machines as well .

No, you can't test this issue here because it may occur under a specific set of circumstances that must intersect. Firstly, it requires a completely filled VMU with 0 datas, then there might be some corrupted data within the VMU, along with other contributing factors. Collectively, these factors create a sort of glitch in the system, where a limited set of games check the availability of the original VMU and then interact with it to display the game image on the VMU screen. When the data doesn't pass through correctly, it results in a black startup screen. Even if you remove the VMU, the data remains frozen somewhere, causing the block. To resolve the situation, you need a second empty VMU to provide an electrical stimulus to the system and unlock that glitch.

So, don't worry if you haven't encountered this issue, and if you have more than one VMU available, you're in the clear.

But could show, maybe some currepted datas when it's the VMU it full without any block free or what so ever or the position of the "Moon" ....anyway if appear to someone here there is the solution to erease this kind of glitch.

Yeah, even with a completely full VMU, they still boot up fine for me. There must be something very specific about your setup that's causing it. Weird.
