Note:No system version update for DS and DS Lite now.
If flashcart is compatible with higher version, it surely is also compatible with lower system versions. For example, if R4i SDHC V1.4.5 works on DSi Ver 1.4.5, this card can also works fine on Ver 1.4.4, 1.4, 1.4.1 and 1.4.2. if R4i Gold 3DS RTS works on 3DS Ver 11.0.0-33, this card can also works fine on Ver 11.0.0-33, 10.7.0-32, 10.6.0-31, 10.5.0-30, 10.4.0-29, 10.3.0-28, 10.2.0-28, 10.2.0-28, 10.2.0-28, 10.2.0-28, 10.1.0-27, 9.9.0-26, 9.8.0-25, 9.7.0-25, 9.6.0-24, 9.5.0-23, 9.5.0-22, 9.4.0-21, 9.3.0-21, 9.2.0-20, 9.0.0-20, 8.1.0-19, 8.1.0-18, 8.0.0-18, 7.2.0-17, 7.1.0-16, 7.1.0-15, 7.1.0-14 and 7.0.0-13.

3. Is there flashcart compatibility difference for consoles from different zones/region ?
No such difference. For example, if R4i SDHC 3DS RTS card works fine on 3DS Ver 11.0.0-33U, it can work on 3DS Ver 11.0.0-33E, 11.0.0-33A, 11.0.0-33J. (U - American version, E - European, A - Asian, J - Japanese version)!
