I originally thought might have confused it with the X68K, whose it's closeness to arcade hardware such as Capcom CPS-1 allowed for near (but not fully, contrary to popular belief) perfect ports possible at the time. (Capcom even sold a Genesis/SNES controller converter for X68K for the Street Fighter II ports.) However, the FM Towns does have its own share of arcade ports, mainly involving Sega, Taito and Capcom titles, such as After Burner, Operation Wolf and Super Street Fighter II, respectively.
On FM Towns side, their commercial games list appears to be intermediate between X68K's "arcade at home" experience and PC-98's graphics that prioritize RPGs and visual novels (often smut in nature) due to PC-98's graphics capabilities that benefitted static graphics. (No PC-98 mention/discussion is complete if eroge is not brought up at one point anyway.)
