Hey, like 10 years ago or something my dad got an r4 card for my dsi and i played a crap ton of games on it. recently i've found my old dsi again and tried playing the games again. but when i tried launching the application, I just get a black screen and it says an error has occured. i asked my dad but he doesn't remember. so i tried finding the solution myself but i really don't know what to even do, so im posting this. my dsi is on version 1.4.5U. ill post pictures of what I have and what error I get when launching so maybe you guys can try figuring it out. oh btw, if i have to download from any links, can you make sure they work cause lot's links I've tried to find the solution myself haven't worked.
