Title: Preserving the Bits: Understanding Sega EPROMs like Epr-18022.ic2
Body: If you are an arcade enthusiast or a MAME user, you’ve likely encountered cryptic file names like Epr-18022.ic2 while auditing your ROM sets. While it looks like a random string of characters, this filename actually tells a story about arcade hardware preservation.
What is Epr-18022.ic2?
The naming convention "Epr" typically indicates this is a dump from a standard Sega EPROM chip. The number (18022) is the specific game or revision code, and the .ic2 extension usually denotes the physical position of the chip on the arcade PCB (Printed Circuit Board).
Why is it missing? MAME is incredibly strict about accuracy. If you see an error requesting this file, it means your set is incomplete. This file likely contains crucial data—possibly character sprites or background tiles—that the emulator needs to render the game correctly.

I’m trying to source a clean dump of Epr-18022.ic2. From what I understand, this is an EPROM chip associated with the Sega System 16 / 18 era hardware (likely used for graphics or program data).
Every time I load the parent ROM, MAME is flagging this specific file as missing or incorrect. I’ve tried merging sets, but the specific .ic2 file extension seems to be eluding me. Arcade preservation is about keeping these specific hex
Does anyone have the correct MD5/CRC for this file? Or is there a specific parent set I need to merge this from? Any guidance on where this specific chip fits in the memory map would be awesome.
Thanks in advance!
