AA5 and AA6 sold fine on the 3DS.
The modern collections are selling well: AA1-3 is over 4.3m. GAA1-2 just sold over 1m. AA4-6 and AAI-2 are close to selling 1m.
The only recent game that "bombed" was GAA2's original release; a Japan-only 3DS game released in 2017.
What killed franchise is Capcom's lack of interest after the 3DS-era and their focus on big budget AAA titles. Capcom's smaller franchises have been left by the wayside.
