I have a problem with your Neosd bought this week.
It worked 20 ~ 30 minutes -> 4 flash games: - /
Since the first use there was artifact during flashing games ...
it was getting worse at each flashing
I took pictures if you have an email address I send them to you.
then another problem appeared:
when the sd card is inserted the console remains on a black screen I tried another card sd new is always the same ...
when I remove the card from the cartridge the console launches the last game flashed in memory
when I put the card in the cartridge and restart the console there is again the black screen ...
I am disappointed and I'm worried for the future because the cartridge that I have buy is unusable!
that's why I'm asking you to replace the Neosd cartridge.
I want to point out that my neogeo works very well with original cartrige the proof !!!
And i have one original bios.
This is the pictures of neosd failure :
thank you for your reply
