# Bugs and Glitches These are known bugs and glitches in the original Pokémon Emerald game: code that clearly does not work as intended, or that only works in limited circumstances but has the possibility to fail or crash. Fixes are written in the `diff` format. If you've used Git before, this should look familiar: ```diff this is some code -delete red - lines +add green + lines ``` ## Contents - [RNG does not get seeded](#rng-does-not-get-seeded) ## RNG does not get seeded **Fix:** Add the following function to [src/main.c](https://github.com/pret/pokeemerald/blob/master/src/main.c): ```diff +static void SeedRngWithRtc(void) +{ + u32 seed = RtcGetMinuteCount(); + seed = (seed >> 16) ^ (seed & 0xFFFF); + SeedRng(seed); +} ``` And edit `AgbMain`: ```diff ... RtcInit(); CheckForFlashMemory(); InitMainCallbacks(); InitMapMusic(); + SeedRngWithRtc(); ClearDma3Requests(); ... ```
