In Sprite Mode 2, bits 0 and 1 of reg 5 should be set (according to the
V9938 Technical Data book). If you reset them, funky stuff happens. :-)
The behaviour I found was exactly like what you observed. Bits 1 and 0 are
a mask over the sprite number, before the look-up in the sprite colour
table is made.
If bit 2 is reset, the colour table and attribute table are at the same
address (which is hardly useful).
