- gen1 recomp transforms Pokémon Red, Blue, and Yellow through a modern recompilation framework.
- Base setup requires the gen1 recomp application and a legally dumped ROM from a supported cartridge.
- 3D visuals come from the separate Voxil mod, imported through the application’s Mods menu.
- Best first settings include Advanced colors, a comfortable voxel level, and a preferred zoom.
- Troubleshooting starts with matching the correct game tab, device build, and mod archive.
gen1 recomp 3D Mod Overview
gen1 recomp is a modern way to experience the original Pokémon Red, Blue, or Yellow structure with configurable visual enhancements. The core application loads a compatible game ROM, while the Voxil 3D mod adds block-based environments, optional 3D battles, expanded lighting, and additional presentation controls.
The project is best understood as two connected layers: the gen1 recomp application and an imported visual mod. Installing only the application gives you the recompilation experience, but the 3D look requires the separate Voxil archive to be activated inside the app.
| Component | Purpose | Required |
|---|---|---|
| gen1 recomp app | Loads and runs a supported Gen I ROM | Yes |
| Red, Blue, or Yellow ROM | Provides the original game data | Yes |
| Voxil 3D mod | Adds voxel-style environments and visual options | Optional for 3D |
| Device build | Matches the hardware or operating system | Yes |
| In-game options | Controls colors, zoom, battles, and lighting | Recommended |
Base Recompilation
Import a compatible Red, Blue, or Yellow ROM, then launch it through the correct game tab.
Voxil Presentation
Add 3D environments, adjustable voxel intensity, battle presentation options, and background fills.
Visual Tuning
Adjust zoom, colors, time of day, lighting behavior, and optional environment curvature.
Install and test the gen1 recomp application before adding visual modifications. Confirm that the ROM opens correctly first.
Step-by-Step Setup Guide
Use this order to keep the installation simple. The process applies the same general workflow across supported devices, although file selection and installation prompts can differ by operating system.
Get the Correct Application Build
Open the project’s official release page and choose the gen1 recomp build that matches your device. On Android, the downloaded package may appear as an application after installation. Keep the release archive available until the setup is confirmed.
Prepare a Legal ROM Dump
Create a ROM dump from an officially purchased Pokémon Red, Blue, or Yellow cartridge. Store the file in an easy-to-find folder and avoid changing its filename until the import is complete.
Import the ROM
Launch gen1 recomp and select the matching tab: R for Red, B for Blue, or Y for Yellow. Choose Import ROM, browse to the dump, and wait for the file to load.
Download the Voxil Archive
Obtain the compatible Voxil 3D mod release from its official project channel. Use the release archive intended for gen1 recomp rather than an unrelated development file.
Import and Activate the Mod
Open the Mods menu beside the game tabs, select Import Mod ZIP, and choose the Voxil archive. Return to the correct game tab and press Play.
| Setup Stage | Menu or Action | Checkpoint |
|---|---|---|
| Application | Install the matching release | The app opens without an installation error |
| ROM | Select R, B, or Y | The selected tab matches the ROM |
| Mod | Import Mod ZIP | Voxil appears in the Mods list |
| Launch | Press Play | The game reaches its opening sequence |
| Configuration | Open Options | Visual controls are available |
Importing a Blue or Yellow ROM through the wrong tab can prevent the expected content from loading. Match the tab to the original cartridge version.
3D Visual Settings and Recommended Tweaks
After the first launch, progress through the opening sequence until the in-game pause menu becomes available. Save before changing advanced options, then open Options and locate the visual controls. The exact appearance depends on the selected values, so treat these recommendations as a starting point rather than fixed requirements.
Set the color mode to Advanced to expose the broader visual configuration. The voxel level controls how strongly the 3D environment is displayed. A full setting creates the most pronounced transformation, while lower values can provide a lighter presentation.
| Setting | What It Changes | Starting Recommendation |
|---|---|---|
| Color mode | Expands available color controls | Advanced |
| Voxel level | Controls the strength of the 3D environment | Full, then reduce if preferred |
| 3D battles | Changes battle presentation | Enable only if desired |
| Back sprites | Alters battle sprite presentation | Test alongside 3D battles |
| Zoom level | Changes the amount of visible game space | Choose for screen comfort |
| Void fill | Fills unused areas around the scene | Trees for a natural frame |
The Mods menu may also include additional Voxil options. The V-curve setting can make the environment appear more rounded, while daytime controls alter lighting and shadows. You can select a fixed time, synchronize with the device clock, or use a timed cycle when those options are available in your build.
Classic-Plus
Use a lower voxel level, standard battle presentation, and a moderate zoom for a restrained visual upgrade.
Full 3D
Use full voxel intensity, 3D battles, back sprites, and a tree-filled void for the strongest transformation.
Atmospheric
Experiment with V-curve and changing times of day to emphasize lighting, shadows, and environment depth.
Change a single visual setting, return to the game, and compare the result. This makes it easier to identify the configuration you prefer.
Troubleshooting and Stability Checklist
Most setup problems come from a mismatched build, an incorrect ROM tab, or an archive that was not imported through the Mods menu. Resolve the earliest failed checkpoint first instead of changing several settings at once.
Before Launch:
- Confirm the application build matches the device
- Use a legally dumped Red, Blue, or Yellow ROM
- Select the matching R, B, or Y game tab
- Import the Voxil archive through Import Mod ZIP
- Save in-game before adjusting advanced options
| Symptom | Likely Cause | Recommended Action |
|---|---|---|
| App will not install | Incompatible device build | Download the release matching the operating system |
| ROM is not recognized | Wrong tab or unsupported file | Select the matching game tab and verify the dump |
| 3D view is unchanged | Mod was not activated | Reopen Mods and confirm Voxil is listed |
| Visuals look crowded | High voxel level or zoom | Lower voxel intensity or adjust zoom |
| Lighting feels unusual | Time-of-day controls are active | Choose a fixed time or disable cycling |
| Battle view is unfamiliar | 3D battles or back sprites enabled | Toggle one battle option and compare |
If a release includes updated patches or experimental features, review the project’s official release notes or community channel before replacing a working installation. Keep a backup of your configuration and original ROM dump so you can return to a known-good setup.
Do not overwrite a stable build while testing an experimental update. Keep the application, ROM backup, and mod archive organized in separate folders.
FAQ: gen1 recomp Setup
The following answers cover the most common questions about the 3D workflow, supported game versions, and visual customization.
Q: What games does gen1 recomp support in this setup?
The setup described here uses Pokémon Red, Blue, or Yellow ROMs. Choose the R, B, or Y tab that matches the game data you legally dumped.
Q: Is the Voxil 3D mod required?
No. The base application can be tested before adding Voxil. The separate mod is needed for the voxel-style 3D environments and related visual options.
Q: Why does my game still look mostly original after installation?
Confirm that the Voxil archive was imported through Mods, verify that it appears as active, and check the voxel level under the in-game options.
Q: Can I change the time of day?
When the installed Voxil build exposes the feature, you can select a time, synchronize it with the device clock, or use a timed cycle. Availability can vary by release.
Record the application version, game tab, mod archive, and preferred settings whenever you finish a working setup. This makes future troubleshooting faster.
