Segatools is a versatile wrapper and loader used primarily within the arcade rhythm game preservation community to run SEGA arcade software, like Ongeki, on standard PCs. When enthusiasts discuss "extra quality" in this context, they are typically referring to achieving a "pixel-perfect" or high-fidelity reproduction of the original arcade experience while bypassing hardware-specific restrictions. Core Functions of Segatools
Segatools acts as a bridge between the game software and your PC hardware. Its primary roles include:
Hardware Emulation: It emulates the specialized IO boards (like the SEGA Nu series) so the game "thinks" it is running on genuine arcade hardware.
Input Mapping: It allows standard PC peripherals (keyboards, gamepads, or custom rhythm controllers) to function as the arcade buttons, side sliders, and levers.
Network Redirection: For games like Ongeki that require a server connection for profile saving and unlocks, Segatools redirects the game to private local servers (e.g., Aqua or Minime). Achieving "Extra Quality" in Ongeki
To reach a high-quality "arcade-accurate" setup for Ongeki using Segatools, several technical layers must be optimized: Resolution & Display (High Fidelity)
Native Aspect Ratio: Ongeki uses a unique vertical (Tate) 1080x1920 display. "Extra quality" setups use monitors capable of rotating 90 degrees to match this layout exactly, preventing scaling artifacts.
Refresh Rate Sync: The game is designed for 60Hz or 120Hz depending on the version. Locking the frame rate ensures smooth note scrolling and prevents "stutter" that can ruin high-level play. Audio Latency Optimization
Arcade rhythm games are extremely sensitive to audio lag. High-quality setups often utilize ASIO drivers or specialized sound cards to minimize the delay between a button press and the game's sound feedback. IO Polling Rates
Standard USB polling can sometimes introduce micro-delays. Advanced users configure Segatools to work with high-polling rate controllers (1000Hz) to ensure that the rapid tapping required for "LUNATIC" difficulty charts is registered accurately. Peripheral Emulation (The "Slider")
The defining feature of Ongeki is the analog slider. Achieving "extra quality" often involves using dedicated hardware, such as the YuanCon or DJ Dao controllers, which Segatools maps to provide authentic analog tension and response. Technical Implementation
The configuration for these quality-of-life improvements is typically handled within the segatools.ini file. Key sections often include:
[vfs]: For high-speed file loading and redirecting save data. [io4]: For configuring high-accuracy input responses.
[dns]: To ensure stable connection to the backend server without timeouts.
Warning: Segatools is intended for researchers and hobbyists working with software they legally own. Using it with pirated software is against the terms of service of the original developers.

is a set of open-source DLL wrappers and tools designed to emulate arcade hardware environments on standard PCs. For Ongeki, these tools are essential for handling the game's unique input requirements and hardware checks. Key Performance & Quality Factors Input Precision (IO Quality):
The game's "quality" depends heavily on the input library (e.g., ) used with segatools. Ongeki requires a six-button layout and a lever/joystick for navigation and dodging bullet-hell elements.
High-quality setups using these tools aim for minimal input lag, which is critical for achieving top-tier scores like "SSS" or "All Critical Break". Emulation Features: Segatools allows for the emulation of the Segatools is a versatile wrapper and loader used
, which are necessary to bypass original arcade hardware restrictions. Graphical Fidelity:
The game supports various resolutions through configuration, though performance is tied to your local hardware's ability to maintain a steady framerate during intensive "bullet-hell" sequences. Arcade vs. PC Experience Scoring Accuracy:
Reviews from players using these setups indicate that while technical scores (Note/Bell scores) can be perfectly replicated, the "Battle Score" depends on character card stats. Reliability:
Community-maintained tools like segatools are frequently updated to improve stability and fix bugs related to specific game versions like Ongeki Plus Ongeki Bright
It is vital to note that Segatools and game dumps are for preservation and education only. SEGA has not authorized the distribution of Ongeki for PC. To legally justify an "Extra Quality" build, you typically need to own the original arcade hardware (an ALLS HX2 unit) or the physical game data from a decommissioned cabinet.
That said, the community views this as a way to keep Ongeki alive as arcades decline globally.
| Feature | Standard Arcade | Segatools Extra Quality | | :--- | :--- | :--- | | Render Resolution | 1360 x 768 | Monitor Native (e.g., 1920x1080+) | | Aspect Ratio | 16:9 (Stretched slightly on cab) | Pixel Perfect 16:9 | | Anti-Aliasing | Post-processing only | Sharper edges due to higher res | | Refresh Rate | Locked 60 FPS | Unlocked (Monitor Native Hz) |
Important Note: Enabling enableRes=1 is the definition of "Extra Quality" for Ongeki. However, it puts the game engine into an untested state (as the arcade hardware never runs this high). Some UI elements (like the touch UI overlays in the cab) may not scale perfectly, though the gameplay UI (notes, enemies, explosions) scales dynamically and looks significantly better.
This guide explains how to enable "Extra Quality" (high-resolution textures and assets) for ONGEKI
when using the segatools environment. This feature allows the game to run with higher visual fidelity than the standard arcade cabinet settings. 1. Prerequisites
Before modifying settings, ensure your setup meets these requirements:
Storage Space: The "Extra Quality" assets (often found in an option or ext folder) can add significantly to the game's file size.
Hardware: A dedicated GPU is recommended to maintain a stable 60 or 120 FPS at higher resolutions.
Segatools: An updated version of segatools (or a compatible fork like minime) properly configured for your hardware. 2. Locating the Configuration
Most "Extra Quality" toggles are handled within the segatools.ini file or a specific ongeki.ini located in the game's binary folder (usually bin). Navigate to your game's bin folder. Open segatools.ini using a text editor like Notepad++. 3. Enabling Extra Quality
In your configuration file, look for the [graphics] or [patches] section. If the following lines do not exist, you may need to add them manually: Arcade players who want tighter timing and better replays
High-Resolution Assets: Ensure the path to the extra data is recognized. In many setups, this is automatic if the folder option exists in the root directory.
Resolution Scaling: To actually see the quality improvement, you must set the game to run at a higher resolution (e.g., 1080p or 4K). [graphics] width=1080 height=1920 fullscreen=1 Use code with caution. Copied to clipboard
Texture Patches: Some versions of segatools include a patch section to force high-quality modes:
[patches] # Set to 1 to enable high-quality textures if supported by your version extra_quality=1 Use code with caution. Copied to clipboard 4. Folder Structure Verification
For "Extra Quality" to work, the game files must be organized correctly. Your directory should look similar to this: Ongeki/ app/ (Main game files)
option/ (This is typically where Extra Quality data resides) bin/ (Executable and segatools.ini) 5. Troubleshooting Common Issues
Black Screen on Launch: This usually means your GPU cannot handle the forced resolution or the "Extra Quality" files are missing/corrupt. Revert the width and height in .ini to test.
Stuttering: If the game lags with Extra Quality enabled, check if v-sync is enabled in your GPU control panel and ensure the game is running on your dedicated graphics card rather than integrated graphics.
Assets Not Loading: Verify that the option folder contains the actual .amfs or asset files. If the folder is empty, "Extra Quality" settings will have no effect.
segatools ongeki extra quality thrives because it's shaped by its users—players report odd edge-cases, chart authors provide test files, and devs iterate quickly. This loop of feedback produces tools that feel responsive to real-world play: not just what engineers assume players need, but what players actually encounter in arcades, on PC rigs, or through custom cabinets.
Ongeki uses a unique horizontal touch screen. Most players don't have a 48" horizontal touch monitor, so they use a mouse or drawing tablet. An "Extra Quality" configuration implements raw input with 1:1 pointer fidelity, removing the artificial mouse acceleration and smoothing that cripple standard builds.
Segatools is an open-source emulation and patching layer designed specifically for SEGA’s ALLS and Nu arcade hardware. It acts as a middleware, translating your PC’s Windows environment into something the Ongeki game executable can understand.
It handles:
Without Segatools, the Ongeki dump is a brick. With it, your PC becomes a SEGA arcade cabinet.
Installations are designed to be approachable: guided calibration wizards, visual feedback during tests, and contextual help reduce the intimidation factor. For advanced users, verbose output, exportable JSON logs, and plugin hooks enable deeper automation and integration with stream overlays, stat trackers, or training bots.
