I think I already inserted the Super Monkey Adventure text. I just never quite got up the urge to get a working title hack inserted. ... and to actually play through the game.
I could be wrong, but I thought the reason for doing DQ3 was due to its mapper. DQ3 was a 256KB MMC1 game, which is the limit of a normal MMC1 game.
DW3 as well as both DQ4 and DW4 were 512KB, which requires a variant mapper, so I'd guess DQ3 was probably emulated first.
I do remember it was quite awhile before someone figured out DW4 is NOT 1MB, and thus Nesticle, popular emulator of the time, emulated the bad 1MB dump at the expense of the good 512KB dump working.
