Hi gurus,
I bought a PAL dreamcast without optical drive and installed a GDEMU clone on it, changed the fan and added the resistors on PSU. I use a microSD card (16GB raspberry pi3b card) inside an SD adapter.
Changing adapters and different microSD card yield to the same result:
Usually the first time it does boot up fine, entering the games and playing them. However, especially when I restart dreamcast iIt happens either one of these cases:
1) black screen until a stuck dreamcast logo already in central position (no animation)
2) enters GDEMU but goes black screen after starting the entry menu
3) stuck when loading at SEGA logo
Any help would be really appreciated!
