ROM Naming Observations

Good Naming (No-Intro/Redump style)

N64: 007 - GoldenEye (USA).n64 - Full No-Intro set, excellent naming
GameCube: Fire Emblem - Path of Radiance (US).rvz - Clean Redump naming
PS2: Shin Megami Tensei - Nocturne (USA).chd - Proper Redump naming
Wii U: Legend of Zelda, The - Breath of the Wild (USA) (En,Fr,Es)-018.wux - Good Redump style

Mixed Naming Conventions (Needs Work)

Switch: Mixed bracket notation [Title ID][Version] - varies wildly
- Example: Animal Crossing New Horizons [01006F8002326000][v1441792](1G+1U+3D)(MOD11.0.0).xci
- Some have source site tags: (nsw2u.com) embedded
PS2: Inconsistent case/underscore usage in some titles
- Killer7_PS2_NTSC-U.iso vs Kingdom Hearts (US).chd
PSP: Mixed underscore naming
- Final_Fantasy_Tactics_War_of_the_Lions.iso

Identified Issues

Switch Duplicates (Same Game, Multiple Versions)

Mario Tennis Aces: Base NSP + Updated XCI + folder with base+update
Link's Awakening: Two versions (apostrophe vs no apostrophe)
Super Mario 3D World: XCI + multiple NSP files

Cross-Platform Duplicates (Space Optimization Opportunities)

Bayonetta 1 & 2: Both Switch AND Wii U versions (~45 GB duplicated)
Breath of the Wild: Both Switch AND Wii U versions (~26 GB duplicated)
DK Tropical Freeze: Both Switch AND Wii U versions (~20 GB duplicated)

Recommendations

Switch cleanup: Remove duplicate versions, standardize to XCI with updates
Cross-platform: Consider keeping only the better emulated version (usually newer console)
PS2: Convert remaining 8 ISOs and 3 ZSOs to CHD for consistency
GameCube: Convert 2 remaining ISOs to RVZ
Wii: Convert 3 ISOs to RVZ for consistency

Storage Optimization Opportunities

Format Conversion Candidates

Current Format	Target	Potential Savings
PS2 ISOs	CHD	40-60% compression
GameCube ISOs	RVZ	Already converted mostly
Wii U WUX	Already compressed	N/A
PSX ZIPs	CHD	Would need extraction first

Duplicate Reduction

PSX Redump set includes all regions - filtering to USA could save ~40 GB
Some games exist on multiple platforms (Bayonetta on Switch + Wii U)

Missing or Incomplete

Systems with Few ROMs (Acquisition Opportunities)

System	Count	Status	Priority
PS Vita	0	Vita3K installed, NO ROMS	HIGH
PS4	0	ShadPS4 in early stages	LOW
Wii	6	Missing many essentials	MEDIUM

File size validation
Bad dump pattern detection
Archive integrity (zip/7z)
Corrupt file detection

bash

# Quick check (default)
./rom-integrity-checker.sh

# Check specific system
./rom-integrity-checker.sh --system ps2

# Full hash verification (slow)
