v0.1.9-alpha

Version 0.1.9-alpha

- Uses historical temperature data for six cities along
the trail to generate temperatures while traveling.
- Saves approximately 2 kilobytes of PRG-ROM by updating
the DisplayNumberHundreds and DisplayNumberThousands macros
to use subroutines for bulk of code.
- Highlights current name on alphabet screen. However, this
may not be enough of an indicator. I may need to use a sprite
for an indicator, and cycle through which sprites are
active (causing flickering).
- Tweaks title screen colors so wagon cloth is white rather
than pinkish.
- Adds "very poor" health status icon and "snow" and "snowstorm"
weather status icons. Tweaks other status icons.

v0.1.8-alpha

Version 0.1.8-alpha

- Update font to a thicker version using mostly the same
characters as the Commodore 64, based on a reference
image I found. A few characters have my own tweaks.

v0.1.7-alpha

Version 0.1.7-alpha

- User can now enter five names for party members
when setting up game.

v0.1.6-alpha

Version 0.1.6-alpha

- Adds "view supplies" screen for viewing current
supply status.
- Adds some small landmark icons, however adds
compile-time define for disabling them as the code
for making them move in line with the miles traveled
each day is wonky.

v0.1.5-alpha

Version 0.1.5-alpha

- Adds screen where player can choose to rest up to nine
days at a time. The maximum number of days to rest at one
time is set in constant REST_DAYS_MAX.
- Adds landmark screens for Chimney Rock and South Pass.
- Advances small landmark icon on traveling screen. Only
one small landmark icon has been created so far.
- Fixes bug where each day mileage was advancing haphazardly.
This was caused by the carry flag sometimes being set, throwing
off a calculation.

v0.1.4-alpha

Version 0.1.4-alpha

- Fix a bug where store screens down the trail didn't load properly.
First, the curlandmark had already been incremented, so when we loaded
in the store prices, they were the wrong prices---and because they were off
by one, this meant that the prices were all zeros. Then, the number of oxen
was fluctuating wildly. This was because the calculated total prices for each
of the goods hadn't been initialized to $0, so loading Fort Kearney for example,
it was still trying to adjust for the total prices of goods from Independence.
- Allow user to buy a single ox rather than a yoke of oxen. The game now stores
the oxen as the total count of oxen, rather than the number of yokes.

v0.1.3-alpha

Version 0.1.3-alpha

- Adds functional store screen where player can purchase
supplies. Player is prevented from spending more money
than they have.
- Adds decision screen at the Dalles landmark where the
player can choose to either go on the Barlow Toll Road
or raft down the Columbia River.

v0.1.2-alpha

Version 0.1.2-alpha

NOTE: Pulled v0.1.1-alpha as audio wasn't actually working
properly.

- Adds decision screen for Fort landmarks, allowing player
to choose to go to Store screen or continue traveling.
- Adds decision screen for Blue Mountains landmark, allowing
player to choose to divert to Fort Walla Walla or go straight
on to the Dalles.
- Adds landmark screen for starting point of Independence, MO.
- Rearranges order of initial screens during game setup,
including removing the "set pace" screen from game setup.
- Paused screen now includes menu options to set pace and set
food rations.
- Adds songs to title screen and most of the landmark screens.
However, audio isn't working properly, and so added a conditional
define to not include audio support. Audio is still compiled in so
we can see the amount of free space in the ROM, but the calls to the
audio functions aren't made.

v0.1.0-alpha

Version 0.1.0-alpha

- Add screens where player can set starting pace, starting
month for journey, and their occupation.
- Display accurate number for food remaining on
status bar.
- Create Makefile for compilation to replace batch
file scripts, and tweak files to allow for compilation
on Linux as well as Windows.
- Fix bus conflict error when bank switching, exposed
when I tested the ROM in FCEUX.

v0.0.9-alpha

Version 0.0.9-alpha

- Add slightly more complex landmark screen for
Big Blue River Crossing.
- Fix glitch where unpausing would reset the mileage
remaining to the next landmark.
- Add routine for drawing 4-tile metatile, and refactor
oxen and wagon metatiles to use it.
- Display latest commit number on title screen. This should
help when preparing .nes files for distribution for testing.
