This is a Space Invaders theme i made for YSMenu.It also includes an ini file wich you need to overwrite your old one cause i edited the colors.EnjoyReminder: Don't forget to also include the ini file.
For me if you want to emulate the DS the best option is on Android, use DraStic and a controller that holds your phone... it's clunky but it works insanely well. The next best option in my opinion is using a New 3DS XL, not really emulation but hacked it works really well.
As about DS, it's from the few consoles I prefer playing on the actual hardware, especially because of the consoles' hardware that make it not so practical to emulate (double screens, touch countrols etc). Besides DS and is cheap and flashcards are cheap as hell. Or you can buy a 3DS and mod it so you can play DS games too (since 3DS officially has back compatibility with DS games
