Not to be rude or anything, but as you can clearly read me and one other person already tried that method and it doesn't work. Your previous firmware v3 doesn't fix anything.
I don't mind
@Localhorst86 trying, but you are not looking in the correct direction to fix this anymore... There isn't anything in the previous firmware that has any solution to solving this problem, we have established that.
Localhorst86 is describing the same problem we are having. It kind of seems to create a new save file or loading a save file. But actually it does nothing. Tested this with an old savefile created with the EZ FLASH IV. If this savefile was put on the Omega every single device except the SP 101 was capable of reading the save. The omega just acted like it was reading writing the save but it did nothing.
A great game to test this quickly is "Riviera the promised land", this because you can instantly save after the first cutcene (that you can skip). And on the save screen it actually gives an error when you try to save on the Omega in an SP 101.
It would be nice if you could communicate if you have any clue on how to fix this. Because me and other people are stuck with a card we can't use. Because for me personally I don't give a single thing about it working in the other devices, because I don't use those devices. My prefered retro gaming device is the GBA SP 101.
And if there is no solution it would be nice if you could make an official statement on your website so we can reference to that when we try to return our product to china or whatever...
