Cause: Incorrect region auto-detection.
Fix: Force emulator to "US NTSC" or "Auto" – do not use "Europe PAL" for US ROMs.

Is it worth using in 2026, or should you upgrade? Let’s compare:

| Feature | Cylum 2014 | No-Intro 2026 | EverDrive Pack 2025 | |---------|-------------|----------------|---------------------| | Total ROMs | ~2,000 | 2,850 | 3,200 (incl. hacks) | | Verified dumps | 96% | 99.99% | 92% | | Hacks included | ✔️ (curated) | ❌ none | ✔️ (all, uncurated) | | Pre-patched translations | ✔️ | ❌ | ✔️ but outdated | | Works on flash carts | Mostly | Yes | Yes | | File naming | Clean | Consistent but verbose | Mixed |
