Use the new asan:stack statement2026-04-08T14:10:41ZMiquel Sabaté Solàmssola@mssola.com2026-04-08T14:10:41Zurn:sha1:c3c6f3b4469bf9eadff5763fa16dbbbf15637e57
This allows us to account for the stack on the memory report. Using half
of the $100 page for stack management is most surely overblown, but I
have not really computed how much we are using the stack on this game,
even if I suspect that its usage is actually pretty minimal. Anyways, we
have room to spare in RAM space, so let's reserve half a page for the
stack.

Clear out sprites after the take off animation2026-04-06T19:43:44ZMiquel Sabaté Solàmssola@mssola.com2026-04-06T19:43:44Zurn:sha1:f9ca8ca80b9d0cf0d54f9aa59a3fbb517c37fc9c
This was hidden before commit 134c671e18b6 ("Cancel the take off
animation before shuttle change"), as the sprites and the background
matched perfectly. That wasn't the case in the case where the shuttle
kind was to change.

Just as it was on the original game, if we cleared the stage right
before changing the shuttle kind, then we don't go down again.

We want every shuttle kind to appear at least once before rewarding the
player with the coin.

Add a table with tile IDs for shuttle parts2026-04-03T20:32:52ZMiquel Sabaté Solàmssola@mssola.com2026-04-03T20:32:52Zurn:sha1:1963d7d8dd70ee9bc4cf9b81363aeab440a6f786
This will allow us to select the proper shuttle depending on
'Globals::zp_shuttle_kind'. Hence, now only the actual shuttle parts on
the CHR file are missing, which is why I left a couple of TODOs on the
table itself.

Cycle the kind of shuttle to be used2026-04-02T12:40:12ZMiquel Sabaté Solàmssola@mssola.com2026-04-02T12:40:12Zurn:sha1:cb1111055f7b03989daac63675d27bfd156a4e21
In preparation to having multiple kinds of shuttles as in the original
game, introduce the 'Globals::zp_shuttle_kind' variable, which is just a
helper value by masking out the 'Globals::zp_level' variable. This in
turn will be the index for selecting which tile IDs for each shuttle
part.
