  1. Can you give a code for fire red rom hacks too.
    Because of the game red chapter its still need real time clock to trigger some events.

  2. I had to turn on ‘real time clock’ and use your .ini file. Thank you!

    The berries I planted never germinated, and it was obvious that the battery/clock problem was the reason. I turned on the real time clock, and when I reloaded the game the next day, the planted berries were all gone. I tried replanting… failed. Reloading and retrying an older saved game… failed. So I tried your .ini file. I did not do an exhaustive test, but the first couple variations also failed.

    I finally had success when I turned on real time clock, used your .ini file, and started a new game. My berries grow! In case it’s useful, here’s my system info: Windows XP, SP3, VisualBoyAdvance 1.8.0.beta3
