Hi, again,
I already thought of that, also I thought what it could be a power supply problem, so I use an external power supply, connected to the 5v from usb using wires and powering the cartridge directly with it. But it didn't work either, look at the picture. But I'll try again.
But I hadn't thought to check the roms written on the sd card, I thought that it was a correct reading, good idea, thanks, in this case I should install an emulator on my PC or I can use the Everdrive to check the roms. I will prove it.
Relative to the powering the cartridge directly with 5v Ummhh, good idea but I had not thought about that, what happens is that I love very much my cartridges and I wouldn't like to see anyone die with 5v, but I think it 
Thank you, until tomorrow, I'm going to bed, I'm very tired.
