Annual FY Japanese HW Shipments;
I think Note 1 says that for Nintendo shipments 1993 is 15 months from Jan 93 - Mar 94. 1992 and prior is calender year, 1994 and later is Apr - Mar.
Mega Drive: 88 and 90 deviate from this
, and results in a too low LTD. 91 onwards does agree.
Game Gear: Disagrees with the limited amount of data in this thread. Adds up to too high LTD.
Mega CD: Matches all data posted
Saturn: Matches this
, and all data posted.
Dreamcast: Also gives 200k for 01/02, plus a further 6k for 02/03. 98/99 doesn't seem to split Asian sales from that year.
For Sega it seems that data for MCD onwards is accurate for Mar-Apr, but earlier numbers seem off. Maybe mixing CY and FY as with Nintendo?
PC Engine: Figures match posted data, numbers are close to imprecise pixel counting
PC-FX: Numbers match here bar 0.01m difference in LTD which can be explained by rounding.
3DO: Matches known figures, but doesn't mention Sanyo. Unclear if Panasonic only or Sanyo is included too. Probably the latter.
