Hey people, I need your kind help with some information, really need to hear if any of you got the Adapter's VMU correctly working.
I've build this project been sometime now, made a PCB and everything, It seems that a lot of connection problems have been solved after that, but I'm having problems with the VMU operations
The problems:
1) Using a 25PE16, only 8 of the 16 VMUs are really available, the others simply doesn't show
2) The available ones fail formating through the Dreamcast bios, After rebooting the system, the formated VMUs show 0 blocks available.
3) Formating through VMU tool fail too, but after reboot, the VMU show correctly with all the blocks available
4) Saving game to the VMUs formated in #3 wont work all the time, almost always give a fail message but it clear and saves if the STM32 is reset.
5) Copying a file from the Adapter VMU to a real VMU works flawlesly, but copying a file from a real VMU to the adapter always fail and corrupt the file, sometimes the whole adapter's VMU.
6) I've bough 5x 25PE16, but all from the same lot. All of them show the same problems with varied degrees. I suspect they maybe bad, but need to be sure.
I want to know if somebody has been able to use the adapter's VMU, formating, saving games, etc, without these problems. I need to know because I suspect that maybe all my 25PE16 are bad, if so I will buy new ones from a new supplier, but before that, I would like to know if this is really the case.
Thanks,
