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:

RNG does not get seeded

Fix: Add the following function to src/main.c:

+static void SeedRngWithRtc(void)
+{
+	u32 seed = RtcGetMinuteCount();
+	seed = (seed >> 16) ^ (seed & 0xFFFF);
+	SeedRng(seed);
+}

And edit AgbMain:

	...
	RtcInit();
	CheckForFlashMemory();
	InitMainCallbacks();
	InitMapMusic();
+	SeedRngWithRtc();
	ClearDma3Requests();
	...
