 Start the hyperspace countdown (for both inter-system hyperspace and the
 galactic hyperdrive).

\
\ LDA #15               \ The hyperspace countdown starts from 15, so set A to
\                       \ 15 so we can set the two hyperspace counters
\
\ STA QQ22+1            \ Set the number in QQ22+1 to A, which is the number
\                       \ that's shown on-screen during the hyperspace countdown
\
\ STA QQ22              \ Set the number in QQ22 to 15, which is the internal
\                       \ counter that counts down by 1 each iteration of the
\                       \ main game loop, and each time it reaches zero, the
\                       \ on-screen counter gets decremented, and QQ22 gets set
\                       \ to 5, so setting QQ22 to 15 here makes the first tick
\                       \ of the hyperspace counter longer than subsequent ticks
\
\ TAX                   \ Print the 8-bit number in X (i.e. 15) at text location
\ JMP ee3               \ (0, 1), padded to 5 digits, so it appears in the top
\                       \ left corner of the screen, and return from the
\                       \ subroutine using a tail call
