The Context: The Franchise's Rebirth

• The Hall of Fame Crash: On original hardware, V1.0 had a rare crash when entering the Hall of Fame with a full PC box. On emulators, this is usually mitigated, but save often before the Elite Four.
• Trade Evolution Failure: When trading between a V1.0 ROM and a V1.1 ROM (or a genuine FireRed V1.0), you may experience a "Trainer ID mismatch" visual glitch. The trade works, but the name displays incorrectly.
• Real-Time Clock (RTC) Issues: V1.0 expects the GBA’s physical RTC. On many emulators, the RTC defaults to the wrong year, causing the game to think 2026 is "Year 0," which breaks berry growth. Ensure your emulator is synced to your system clock.
