This is currently hardcoded to 640x480 English builds.
What I've done is temporarily gutted the FreeType2 font renderer, and
instead introduced a system where the font is read from a
pre-rendered font atlas. This allows me to get 100% accurate font
rendering to Windows XP... because I literally created these atlases
with Windows XP.
So not only does this eliminate the issue of FreeType producing
misshapen glyphs, but it also works around the copyright issue
regarding bundling the Courier New and MS Gothic fonts with CSE2.
You see, font files can be copyrighted like any old software, however
typefaces have a lot less protection - they're basically fair-game.
IANAL, of course - look it up yourself.
I don't really want to throw away the FreeType font system since I
spent a ton of time working on it, it allows you to use other font
files, and I'll probably wind up needing it for CSE2EX. I guess I'll
just have to find some way to either have the two systems coexist, or
make it so one or the other can be selected at compile-time.
The old locking/unlocking API was plain inefficient. Soon I'll move
upscaling to the backend anyway, to minimise the overhead where
possible.
Currently only the software renderer has been updated.
Previously, the window was a fixed size just like the original.
This change highlights a weird issue in CSE2: this doesn't exactly
match the behaviour of the original game, so why did I change it?
Simple: monitors had much lower pixel-densities back in the early
2000s, meaning that 320x240 and 640x480 weren't as laughably small as
they are today.
I like to think of CSE2's portable branch as Cave Story's equivalent
to Chocolate Doom: the point isn't to replicate the game's behaviour
100% - that's the accurate branch's job - no, the point of the
portable branch is to replicate the *experience* of the game, as it
was back in 2004. This means no commically-small windows.
This is the same reason font anti-aliasing is disabled, even in
versions of Windows later than XP.
Sidenote: the OpenGL3/OpenGLES2 renderers already had this feature,
but they used linear-filtering, causing the screen to be extremely
blurry in 320x240 mode. This renderer uses a better method, which
does apply slight blurring at the edges of pixels at resolutions
that aren't an exact multiple of 320x240/640x480, but otherwise it
resembles nearest-neighbour. This is way nicer to look at, and fits
the game's aesthetic. This feature will be ported to the other
renderers soon.
