But "Firmware version 2.00.X." was released in this update.
There was a big addition to the graphics function that I could say "specification change".
- Firmware update
Phoebus, Garry, Allen and Jim have been hard at work getting the firmware improved with the extra time created by the keyboard delay. There are a lot of updates and new features already added to 2.00.X, and we are planning on shipping the Next with this core out of the box. Check out the partial features set:
- L2 Priority colours: By setting the first bit of the second byte in a palette entry, this colour now overprints everything regardless of the order of layers, thus providing for a non-cpu time cost solution for environmental masking.
Darken/Brighten modes (by implementing layer colour mixing) has been implemented. SLU modes (111 and 110) with lighting and shadow effects requiring no CPU time also.
- The sprite engine has been redesigned from the ground up allowing for up to 64 sprites per line, 4 bit colour sprites and up to 4x scaling on the X and Y axes.
- NextReg 0x03 writes with bit 7 set now accepted in any mode to change timings (bits 6-4), NextReg 9 bit 3 disables the Kempston mouse port ($DF) and read of NextReg 0x3 bit 7 now returns the next palette byte to be written (0=RRRGGGBB, 1=B-low) and NextReg 0x15 bit 5=1 enables clipping in over border mode for the sprites.

Now that the news about the new core features are out, I am posting this small demo that showcases the new 4bit sprites and the lifting of the 12 sprite per line limit. Note that 4bit sprites are not monochrome, they use a palette of 16 colors, these just happen to use a greyscale palette. This demo uses multiplexing to display 192 sprites on the background (plus 9 for the ball). Then it shuffles the sprite patterns randomly, forming effectively a character map. This allows for a variety of games to be developed that would be very difficult to do otherwise.
Yesterday, the latest article of the official facebook was not displayed.
Therefore, I did not see the update announcement and the movie of the new sprite function demo.
There is some speculation on my post
