Happy 16th, Cave Story!


I made my own 2xRes Cave Story upscale that anyone can use.

Github repo:

Freeware build:

Features of this upscale:

- Base game is 100% complete, from Start Point to end credits, as well as a few (but not all) unused sprites
- Remains faithful to the original art style
- (Hopefully) free of asymmetrical sprites, leftover 1xRes pixels, and other weird inconsistencies seen in the Nicalis upscale
- Compatible with Freeware, CSE2, and Cave Story+
- Made for open community use


Instructions for enabling 2xRes:


Install Clownacy's .DLL mod loader and set sprite_resolution to '2' in /mods/graphics_enhancement/settings.ini

That, or use the Doukutsu2x executable if you somehow have it.


Step 1: Wait for Nicalis to allow CSE2 to exist again

After you have done that: In src/CommonDefines.h, set SPRITE_SCALE to '2', and compile using the instructions in the readme. This define only exists on enhanced branches.

Cave Story+:

Cave Story+ by default supports 2xRes and should be able to load these spritesheets. Just insert them.

Oh wow, nice. This is something a lot of us have been interested in seeing, but it was sort of discouraged for a while when CS Wiiware first came out. Admittedly, some parts of it look a lot like the NICALiS graphics, but in some places that's pretty hard to avoid. I like your different take on the Quote and Curly sprites, that makes their proportions a bit more believable. I was never a huge fan of the art styles that made their heads as big or bigger than the rest of their bodies.

I'm glad you finished this, I can't wait to use it whenever I play Cave Story+. Thanks a bunch.

This is completely bonkers. I think I'm going to replace my actual CS+ graphics with this. Also, i love the character redesigns, can't wait to either redownload CS+ or dig through the internet for a doukustu2x executable.
