Remember: Only use hacks that respect the original game’s balance if you plan to compete online (e.g., in local wireless battles).
For those searching for the "better" ROM for emulation purposes, Omega Ruby is technically stable. Unlike X and Y , which suffered from significant frame-rate drops during battles (especially in 3D mode), Omega Ruby was better optimized for the 3DS hardware. When running the ROM on a PC or Android emulator, the game runs smoothly at 60fps with upscaling capabilities that make it look sharper than it ever did on original hardware. The lack of game-breaking bugs (a notorious issue in the original X/Y save data) makes it a safer, more reliable file to play. pokemon omega ruby 14 3ds rom better
