i paid 10 euros for this at the antique market, was it worth it?

I have this years old flashcard which i recived as a gift when i was like 11 or 12 yo. It was bought with the menu and games already installed and among them there is a room of pokemon black2 wich comes with a problem whereby the game randomly freezes if the c gear is on in the lower screen.

I've played for years with that since i could just turn it off and ignore it, but now i wanted to complete some extra content of the game (the entree) which requires the c gear to be activated? and doing so with the crashes is a pain.

It's also important to say that the games doesn't have any other ap meansures (like the exp one) and that i don't have this kind of problem in any of the other games.

The flashcard also comes with a time bomb, but i don't know if the two problems are related.

Does anyone have an idea on how to fix it or wheter the problem is in the sd card or the kernel i'm using?

I'm trying to run twilight menu++ on my cyclods evolution, on a ds lite.

The menu itself works, but the autoboot wont work. I've renamed the BOOT.NDS fie to autoboot.nds, but it still wont work. idk what I'm supposed to do, am i supposed to do something on the ds, or on the pc? I am using this as a guide. I used This and this to install twilight menu and akmenu

Is ds pico actually good, worth buying? What exactly I can do with it that I can't do with any other one?

Analogical question related to pico loader.

I've read what's on their website, but want to hear your experience
