  "textContent": "Mina the Hollower draws its art with textured triangles at a 256x144 resolution and a custom 64-color palette built to evoke Game Boy Color games. On a modern flat panel, those pixels render as crisp squares. The CRT shader by BonusJZ reintroduces scanlines, glow, and soft blur so the picture reads closer to an old tube display, and it ships with two looks you can flip between in-game.\n\n🎮\n\nQuick answer: Extract the shader files into the game's folder (the one containing the .exe), launch the game, then press PageUp to cycle between the default (sharper) and composite (softer) presets.\n\n* * *\n\n### What the Mina CRT shader does\n\nThe shader overlays a CRT-style filter on top of Mina the Hollower's native sprite output. It adds the kind of scanline merging, color bleed, and subtle phosphor glow that softened edges on real cathode-ray displays. The result keeps the game's intended look intact while smoothing the hard pixel grid that modern monitors expose.\n\nEach resolution file contains two presets. The default preset is sharper, while the composite preset is softer. You switch between them at runtime, so you can compare both without editing files.\n\n* * *\n\n### Requirements before installing\n\nYou need a working copy of Mina the Hollower and access to its installation folder, specifically the directory where the game's executable lives. Pick the shader file that matches your display resolution, since the download is split by resolution.\n\n📁\n\nNote: Installing the shader means dropping files next to the game's .exe. Keep a note of what you add so you can remove it later if you want the unmodified look back.\n\n* * *\n\n### Install the CRT shader for Mina the Hollower\n\n**Step 1:** Download the shader file that matches your resolution from the mod's official page on Nexus Mods. Use the Manual download option from the Files tab.\n\n**Step 2:** Extract the contents into the game's installation folder. This is the same folder that holds the Mina the Hollower executable. The shader files must sit beside the .exe to load correctly.\n\n**Step 3:** Start Mina the Hollower. The CRT filter applies automatically once the game launches with the files in place.\n\n**Step 4:** Press **PageUp** on your keyboard to cycle presets. Each resolution file carries the default (sharper) and composite (softer) options, so a single keypress moves you between them.\n\nYou know it worked when the on-screen image shifts from a clean pixel grid to a CRT look with visible scanlines and softened edges. Tapping PageUp should visibly toggle between the harder and gentler versions of that effect.\n\n* * *\n\n### Steam Deck configuration (Proton)\n\nRunning the shader on Steam Deck through Proton 11 requires a launch option so the rendering layer loads the shader. Set the following in the game's properties under launch options.\n\n\n    WINEDLLOVERRIDES=\"dxgi=n,b\" %command%\n\nWith that override in place, launch the game as normal, and the CRT filter will apply the same way it does on a desktop install.\n\n* * *\n\n### 1440p display settings\n\nFor a 1440p screen, adjust the in-game video options so the shader scales cleanly. Set the pixel size to x9 and set the pixel scale to FIT. This keeps the scanline pattern aligned with the panel instead of producing uneven scaling.\n\n* * *\n\n### Other BonusJZ shaders for Mina the Hollower\n\nThe same author offers additional display filters for the game. Installing more than one adds extra presets to the PageUp cycle, so you can rotate through several looks without swapping files.\n\nShader| Look| Presets included\n---|---|---\nCRT| Scanlines, glow, soft blur| Default (sharper), composite (softer)\nLCD Matrix| Handheld LCD grid| Default (sharper), composite (softer)\nHD| Cleaner high-definition pass| Adds presets to the PageUp cycle\n\nEach of these installs the same way, by extracting into the game folder and launching. With multiple shaders present, PageUp steps through every available preset in turn, letting you settle on the one that matches how you remember handheld games looking.",
