EA archive (official name unknown) is a compressed installer-archive format used in some Electronic Arts software.
Format details
Each archive member has a field for the compression method. Known methods are 0 for uncompressed, and 1 for LZW. The LZW implementation appears to be fairly typical, similar to Zoo but with a maximum code size of 12 instead of 13.
Identification
Files start with byte 0x1a, followed by ASCII "EA".
Sample files
- [1] → .../*.EA
- [2] → *.PEA
- dexvert samples — archive/eaArchive
