(EDIT: since this is doing Numbers, I figured I'd include an actual download link: https://doukutsuclub.knack.com/database#my-mods/mod-details/5ecc783fee5fa10016eef82e/. There's a known bug with upscaled graphics on resolutions other than 480p, I have it fixed, I'm pushing the update for it soon!)
Cave Story is probably the most important game of my life. It led me to meeting some extremely important people, it was my first speedgame, it is a game I can talk about for hours (AND I HAVE!)
But it ain't perfect. Its age has shown, especially as an old 2004 windows only executable. While official ports exist, people have legitimate gripes with them. And so several mods and projects have been born to keep the game alive.
Cave Story: Tweaked was born as a fork of CSE2, a decompilation project for the original freeware release of Cave Story. While CSE2, at least in its accurate and portable branches, aimed at producing code as close to the original game as possible, it had branches aimed at enhancing the base game with niceties and new features (think GZDoom). Tweaked, my fork, aimed at taking it even further, with a healthy dose of inspiration from Celeste's foundational Assist Mode, by focusing on features that improve the game's accessibility.

Thanks to the backend provided by CSE2, I was able to implement hot-swappable fonts choices, ranging from OpenDyslexic to Monogram to Courier New. I also found how to reduce screen shake or eliminate it altogether. There's several other options here like removing screen flashing, reducing the brightness of the background elements, and adjusting volume for Music/SFX
Thanks again for CSE2, there's full controller support.

The star of the show is the Tweaks menu, a name I took from Iconoclasts of all places. This menu contains modifiers to the gameplay itself, allowing players to tailor their own experience. Disable the main experience crystals mechanics for extra challenge, or add infinite ammo to your missiles for that one difficult fight. Toggle full invulnerability or turn the game sideways in Mirror mode.
I've been working on this project on and off for ages. I got some news about it when Nicalis DMCA'd every github repo for CSE2, which also hit mine. Besides that, this mod remains a tool that has allowed so many people to enjoy a game i love dearly, and that's all I was looking for when this project started.
An update to this project is coming along. I've fixed a major issue that made upscaled graphics unusable on fullscreen on several settings. I'm also implementing some further fixes for accuracy and allowing people to use the classic Map System rather than the revamped one Tweaked ships with. I'll let you know once it's up!
Also, there was a 3ds port but it doesn't work anymore and I'm not sure why? it works on citra just fine, did I do something on our 2ds??
