in fact, the card just arrived from Darksoft, he checked the card and he told me it worked there is no problem. The issue might come from my psu or the microsd. I could purchase a reliable psu that most of the people are using. The card arrived 2 days ago. I tested it with the new psu and a microsd sandisk i used before containing the games, the menu was starting normally I could had 3 games, play a little bit with each no issue. Then I wanted to change the game on the slot 1, it was written please wait, and black screen . I switch off the console, wait 10 minutes and switch on again. I arrived to the menu the slot 1 was empty . It could not load the game. I tried another time but it failed again. The micro sd was bad? Ok I bought another one. A sandisk ultra 16 gb class10 A1 , similar to the one recommended by Darksoft. I have installed the pack Darksoft Neo geo 2020 05 , in a file game and update empty . The fw was installed in the card no need to add any thing more than the game in the sd. Then white screen directly after switching on the console containing the cartridge and sd. I tried as well the other sd that I used the previous day, same thing: white screen. I noticed, when I insert back in PC the micro sd there is a new file, close to « game » Named « REVISION ».
I don’t understand
