    Added it to my hack earlier so I decided to just go and release.

    Be sure to give me full credit.
    Edit: I'm a hypocrite lolollo


    I fudged my sources somehow and were unable to recover them properly.
    Here's the ASM
    Spoiler:
    So here's the patch.
    Download the IPS patch

    I am not posting an example script, and to anyone else, PLEASE DO NOT POST AN EXAMPLE SCRIPT ANYWHERE except in your own hack
    Why? Because then i'd see "RTC IN MY HACK" and properly my slightly modified example script. So you'll have to make your own from the data below, sorry for the earlier trouble.

    I use No$GBA and vba-m for testing. :)

    Patches on to the games main loop at 0x41E. Then executes my code at 0xb01000.

    The time it gives you is stored at 0x300553C
    In the following format.
    Year u16
    skip a byte
    month u8
    day u8
    Day of week(mon-sun/1-7) u8
    Hour u8
    minute u8
    second u8

    at 0x3005537
    is
    u8 dayofweek;
    u8 hours;
    u8 minutes;

    use that when you create your time setter function. code auto compensates(I didn't and don't plan on a date thing you can do that on your own)





    Please give me credit.

    Thanks to kawai/ZodiacDaGreat for helping me with an example script.

    Merry Christmas everyone

    So, it's approved uh? Well, here's my contribution. Merry Christmas guys :)

    Spoiler:
    Remember to credit me if you use my code, it's for Fire Red. The RTC is at 0x03004038. The format is:
    [Year][Month][Date][Filler][Hour][Month][Date]
    They are all a byte each in size.

    hmmm, nice present although all it did was destroy what little understanding i had of asm :P

    Um, I think you meant to put that. :P
    EDIT: Also, is it just me, or does this use the Windows clock?
    Does this mean that it wouldn't work on an actual GBA?
     
    Is this RTC identical to R/S/E? Also, if you were to put a FireRed or LeafGreen rom on a GBA Flashcart, would the RTC work correctly?

    I asked you not to post if you don't understand.

    I forgot to add some extra data to my post on how to offset the changes, added it, so please refer to it. And yes it should work on the real GBA, the emulators just base it off of a time() call, so it uses your OS's time.

    So this is better than the R/S/E one? That's cool. Since the R/S/E RTC doesn't work on GBA flashcarts, you should see if you can add your FR/LG clock to R/S/E (and remove the clock that comes with R/S/E so then we don't have to see the "internal battery has run dry" message on a GBA flashcart).

    I guess it depends on whether or not that the flash cart has the RTC chip built in if it doesn't then RTC doesn't work.
     
    Could anyone care to show me how do i insert this?
    At which offset and how do i use it please?
    I'm not very good with ASM yet.
    Must i use setvar 0x8003 or 0x????.
     
    I have no clue what you mean.
     
    No. You just apply it to the game and it runs every frame.

    Did you not read the description?

    Well that's a bummer...

    Would it ever be possible to add a RTC in R/S/FR/LG/E where it works like G/S/C's RTC?
     
    GSC also has a builtin RTC chip.
     
    This is the first ASM script I've compiled correctly! The problem was that I was using devkitARM for THUMB scripts!

    Hehe, I am so stupid sometimes... :P
     
    Can a mod move this thread and rename it plz
