Clear out sprites after the take off animation

2026-04-06T19:43:44Z

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. Signed-off-by: Miquel Sabaté Solà

Cancel the take off animation before shuttle change

2026-04-05T21:57:16Z

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. Signed-off-by: Miquel Sabaté Solà

Add a table with tile IDs for shuttle parts

2026-04-03T20:32:52Z

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. Signed-off-by: Miquel Sabaté Solà

Cycle the kind of shuttle to be used

2026-04-02T12:40:12Z

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. Signed-off-by: Miquel Sabaté Solà

Fix wrong initialization on shuttle reassemble

2026-04-02T05:51:13Z

The shuttle should be reassembled every 4 stages, not 8. I did not remember well how this worked and I jumped ahead with the conveniency of the 'Globals::zp_level_kind' variable. Signed-off-by: Miquel Sabaté Solà

Fix overwrite issues when adding scores

2026-03-27T23:27:09Z

The add_to_player() function relied on parameters to be passed on the 'Globals::zp_tmpX' variables, but that's just plain stupid. First, because these memory addresses are not meant for arguments; but most importantly, because callers actually needed some of these values before calling this function. Hence, everything went into chaos and sprites began to act wrongly in all sorts of random ways. Moreover, some of the callers also needed a guarantee on either the 'x' or the 'y' registers. Since this wasn't always feasible, we needed to store/load these registers' values case by case. All in all, now add_to_player() accepts only one argument via the 'y' register (which callers already knew it was going to be messed with). The value on 'y' has to be set via some helper constants. As a cherry on top, this not only fixes a nasty bug, but it also makes things more performant and with less code. Fixes: 63ef73de3bdd ("Update scores on screen") Signed-off-by: Miquel Sabaté Solà
