You should put the two sprites within one interrupt to get this working
right... I suggest making a little assembly put on the H.TIMI to get this
effect right.

You can, A=VDP(-2) will do the job.
Doh! hehehe, forgot about that one ^^;

Hello,
i'm once again trying to do something with my MSX, and right now i/m

So i was wondering, is there a way to see when to move the sprites
(maybe by use of vrt retr.)? I assume there is because most games i
played don't have this icky movement :-)
You can read bit6 of VDP status register 2 to find vertical retrace:
VDP(-2) and H40
I forgot whether zero or
