v0.97 — IRW header standardized, CARN dedup

v0.97 — 16 pass, 6 fail

IRW Header

• Standardized 0x44-byte header across all modes: magic 0x00640194, data-only size, uint16 LE checksum (trailing odd byte discarded)
• Version string unified to "03/14/95" for all modes
• BIGSREC.EXE compatible

Dedup

• memcmp byte-for-byte verification prevents false checksum collisions
• Per-mode: modern (LOADW) checksum-only, /OLD2 ANIX-only + memcmp, /OLD1 off
• CARN RACKUP and FINGRNT now pass

/OLD2 (Total Carnage)

• SIZX uses IMG_STRIDE(w) for TBL output
• 10/13 TBLs pass (JET/TEXT/TITLE cosmetic SIZX diffs)

Smash TV

• Dedicated loadsmash branch with ROM-verified dedup (u105+u89 EPROM dumps)
• Switch: git checkout loadsmash

Fixes

• BBMUG, MK5MIL restored: modern mode checksum-only dedup
• Consistent .TEXT trailer per mode
• Always-on file header output (Size, Magic, Addr, Dsize, Cksum)
• /R headerless flag documented in README
