CannonBall DX ROM setup
-------------------------------------------------------------------------------

Recommended setup:
Place a current MAME merged outrun.zip in this directory. CannonBall DX reads
required ROM data directly from the ZIP; no manual extraction is needed.

CannonBall DX remains fully backwards-compatible with the traditional setup of
individual extracted ROM files placed directly in this directory.

ZIP entries are matched by CRC32 and uncompressed size, so filenames and
subdirectories inside a merged MAME archive do not need to match CannonBall's
legacy filenames. Extracted ROM files take priority over identical data found
inside ZIP archives.

-------------------------------------------------------------------------------
Alternate early/Japanese course data
-------------------------------------------------------------------------------
The original Japanese/early OutRun program ROMs used by CannonBall provide
slightly different tracks and course ordering.

For a legacy extracted setup, optionally include:
-------------------------------------------------------------------------------
epr-10380.133
epr-10382.118
epr-10381.132
epr-10383.117
epr-10327.76
epr-10329.58
epr-10328.75
epr-10330.57

A suitable merged MAME outrun.zip may already contain these ROMs; CannonBall DX
will locate them automatically by CRC32 and size.

-------------------------------------------------------------------------------
Corrected PCM sample ROM (optional, recommended)
-------------------------------------------------------------------------------
The original opr-10188.71 has the known stuck-data-bit fault. When the fixed
samples option is enabled, CannonBall DX accepts these in order:

1. Sega/M2 official corrected ROM
   CRC32: C2DE09B2
   Current MAME filename: enhanced_203_opr-10188.71

2. Historical CannonBall patched ROM
   Filename: opr-10188.71f
   CRC32: 37598616

3. Original faulty arcade ROM as backwards-compatible fallback
   Filename: opr-10188.71
   CRC32: BAD30AD9

No manual patch is required when the official corrected ROM is available in a
ZIP archive or as a loose file.
