If you've encountered the error message "epr-18022.ic2 (segabill) – NOT FOUND" while trying to launch classic Sega arcade games in MAME, you aren't alone. This specific file is not a game itself but a critical device ROM required for the emulation of the Sega Versus City Billboard Control Board.
Without this small 64KB file, many mid-90s Sega titles—most notably Sonic the Fighters and certain games running on the ST-V (Sega Titan Video) or Model 2 hardware—will fail to boot. Why You Need Epr-18022.ic2
In the world of arcade preservation, MAME doesn't just emulate the game software; it emulates the entire cabinet hardware. The Epr-18022.ic2 file is the BIOS/firmware for the "Sega Billboard" (segabill), a specialized sub-board that controlled the LED displays and 7-segment units on Sega Versus City cabinets.
When you attempt to run a game like Sonic the Fighters, MAME checks for all necessary components. If the segabill.zip (containing epr-18022.ic2) is missing from your ROMs directory, the emulator throws a "Fatal Error" because the machine's required hardware cannot be initialized. How to Fix the "NOT FOUND" Error
To resolve this, you must treat the billboard hardware as a "parent" device or a BIOS file.
The file epr-18022.ic2 is a specific ROM component required for the Sega Billboard driver in MAME. It is part of the segabill.zip ROM set, which emulates the hardware used for Sega’s large-scale electronic billboards or LED displays often found in 90s arcade environments. The Role of epr-18022.ic2 in Arcade Preservation
The preservation of arcade history extends beyond playable games to include the peripheral hardware that defined the "arcade atmosphere." The Sega Billboard was a specialized piece of hardware designed to display scrolling text, scores, or advertisements.
Hardware Function: The "epr" prefix typically denotes an EPROM (Erasable Programmable Read-Only Memory) chip used by Sega. In this specific case, epr-18022.ic2 serves as a BIOS or data chip located at position IC2 on the PCB.
Driver Implementation: Documentation within the MAME source code on GitHub confirms that this file is essential for initializing the display driver. Without it, the "segabill" device remains "NON_WORKING" in the emulator.
Availability: Enthusiasts can find technical details and split/merged ROM sets for this hardware on preservation sites like MDK. The Challenge of Emulating Non-Gaming Hardware
Emulating a billboard presents unique challenges compared to a standard cabinet. MAME developers must reverse-engineer how data is sent to the LED matrix, often without original technical manuals. The inclusion of files like epr-18022.ic2 ensures that the timing and character sets used by the original hardware are replicated with 100% accuracy.
By maintaining these files, the MAME project ensures that the entire arcade ecosystem—from the games themselves to the neon signs and scoreboards—is digitally archived for future generations.

In the world of arcade preservation, individual hardware components are dumped into digital files.
The Hardware: ic2 refers to a specific integrated circuit slot on the arcade's printed circuit board.
The File: Epr-18022 is the dump of the data contained on that specific EPROM chip.
The Role: This file is part of the Segabill (Sega Billboard) driver or BIOS. Sega used this overhead system to drive the logic on many of its mid-90s Model 2 arcade boards.
Without this exact asset placed in the correct directory, emulators cannot recreate the environment needed to boot the specific games tied to it. ⚠️ Why Do You Get the "NOT FOUND" Error?
The most common error users experience when trying to load games like Sonic the Fighters in MAME is:Epr-18022.ic2 (65536 bytes) - NOT FOUND (Segabill) This error usually happens due to one of three reasons:
Missing BIOS Parent File: You downloaded the game ROM (e.g., the zip file for the game itself) but forgot to download the required device/BIOS file called segabill.zip.
Outdated ROM Sets: MAME is continuously updated for accuracy. A file that worked in an older version of MAME might have been redumped or renamed for a newer version.
Misplaced Files: The file is downloaded, but it is not placed in the folder where the emulator is searching for it. 🛠️ How to Fix the Missing File Error
To bypass this error and get your arcade games running, follow these structured steps: 1. Identify the Correct Parent ROM
Rather than searching for the loose file Epr-18022.ic2, you should look for the zipped archive that contains it. In the MAME database, this chip is part of the segabill.zip device set. 2. File Placement
Do not unzip the files! MAME is designed to read compressed .zip archives directly. Find or download segabill.zip.
Drop the segabill.zip file directly into your MAME roms folder alongside your main game zip files. Example path: C:/MAME/roms/segabill.zip 3. Consider an Alternative Emulator
While MAME is an incredible preservation tool, its handling of Sega Model 2 3D graphics can sometimes be demanding or yield visual glitches depending on the MAME version.
Many retro-gaming enthusiasts recommend using the Nebula Model 2 Emulator (often simply called the Model 2 Emulator).

Title: The Ghost in the IC2: Unearthing EPR-18022 for MAME – A Weird Piece of Arcade History
Post:
You ever stumble across a ROM set that just feels… off?
I was deep into a preservation rabbit hole last night—cross-referencing old Japanese arcade service logs—when I found a reference to a file called epr-18022.ic2. No game name attached. No parent ROM. Just a lonely, orphaned chip dump floating in the wild.
Turns out, this isn’t a game. It’s a piece of a ghost.
What is it?
EPR-18022.ic2 is an EPROM (the “.ic2” denotes a specific socket position on a PCB). Based on the numbering scheme and PCB layouts I dug up, it belongs to a rare / prototype / or region-specific revision of a mid-90s arcade board. Think along the lines of Sega’s System 18 or maybe an early Taito F3—something where the graphics and main program are spread across a stack of EPROMs.
Most people have the standard set. But this IC2? It’s a replacement sound CPU or a patched sprite decoder that was never meant for the public. Someone at a repair bench in Osaka in 1998 probably burned this chip, fixed a glitch on one cabinet, and then… the file sat on a forgotten hard drive for 25 years.
Why would you want it?
If you’re just trying to run Sonic Boom or Dinosaur King in MAME, ignore this. But if you’re chasing:
…then hunting down epr-18022.ic2 is your holy grail.
Can you download it?
Yes—but not from the usual “ROM set” sites. You’ll need to look for MAME skeleton sets, non-merged dumps from obscure Japanese preservation archives, or ask directly in the MAMEdev forums. Some kind soul probably extracted it from a repaired PCB last year. Because it’s not a full game, it often gets excluded from merged sets.
One weird thing:
I tried injecting it into an existing parent ROM (choosing a random driver that accepted the chip size). MAME didn’t crash—it just displayed a single kanji character on a black screen, then soft rebooted. That kanji? 待 (wait).
Probably a debug hook. Probably.
TL;DR:
EPR-18022.ic2 is a tiny, orphaned puzzle piece from a forgotten arcade repair. It won’t give you a playable game, but finding it and loading it feels like archeology. If you want to dig, check the latest MAME “non-working” or “source dumps” torrents (v0.260+). And let me know if you get that kanji too.
Has anyone else seen this file? Or did I just invite a cursed ROM into my house? 😅
