## 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();
...
```
This restores the code of Ruby/Sapphire.
**Alternate Fix:** Edit the following function in [src/title_screen.c](https://github.com/pret/pokeemerald/blob/master/src/title_screen.c):
```diff
void CB2_InitTitleScreen(void)
{
switch (gMain.state)
{
default:
case 0:
SetVBlankCallback(NULL);
+ StartTimer1();
SetGpuReg(REG_OFFSET_BLDCNT, 0);
SetGpuReg(REG_OFFSET_BLDALPHA, 0);
SetGpuReg(REG_OFFSET_BLDY, 0);
...
```
This matches what FRLG does and obtains the seed differently than RS, independently of the RTC.
## Scrolling through items in the bag causes the image to flicker
**Fix:** Add the following function to [src/item_menu_icons.c](https://github.com/pret/pokeemerald/blob/master/src/item_menu_icons.c):
