What is the difference between IDSL and NDSL, and what is the difference between fugue and Nintendo?

IDSL and NDSL are different from fugue and Nintendo in nature, and they are both agents and headquarters, that is, fugue is Nintendo's agent in Chinese mainland, DS produced by fugue is called IDS, and so on, because fugue's English name is "iQue".

Licensed products directly support Chinese games, but NDSL uses R4, M3DSR and other recording cards, and also has Chinese menus. NDSL is in the majority in China, because the quality of games not sold to Chinese mainland, such as NDSL, should be better than that sold in Chinese mainland. In fact, many gamers say that the quality of fugue SP is not good, and domestic products always give people a feeling of unstable quality. My DSL is the American version of NDSL.
