During the process of disassembling Spellbound, I found that David Jones included a easter egg in the original ZX Spectrum version. It features a nice starfield that was also included in Knight Tyme (also in the MSX version).
However, I didn't like how the ported starfield routine worked in Knight Tyme; due to the differences between both systems and to the heavy conversion routines, the MSX starfield looked slow and showed a noticeable tearing.
I have chosen to remake the starfield from scratch by using hardware sprites. Even if this routine plots fewer stars (32 vs 50, due to the limitations of the MSX1 VDP) the result is much more MSXish. Stars move faster, they become bigger as they move away from the center and also use several colours.
The starfield is also used in the game ending, so it is the last piece of the puzzle.
Any volunteer for betatesting?
