GBA Utility Tools is a small application for the GBA. Currently it can dump the BIOS, test the Real Time Clock, perform a button test, and perform a sound test. The author hopes to eventually add more features.

How to use the bios dumper said:
Follow the on screen instructions and the bios will be dumped to SRAM. Once that is done take the .sav file and drag it on the GBABiosFixer program. The program will produce a bios that can be used in emulators that need it.

For anyone wanting to use this with the EZ Flash IV cart, here are some instructions that worked for me:

For use with EZ Flash IV: (Works on original GBA, and probably SP, Micro and NDS)
(make sure you have updated the cart to the latest kernel. Check here for updates http://www.ezflash.cn/download/ )

1) Patch GBAUtilityTools.gba with EZ4 Rom Loader, pick the SRAM save size and save it to the SD,
click config, okay and then send.
(leave this file as just .gba)

2) Run it on GBA and follow the on-screen instructions, then turn it off and back on.
(THIS STEP IS IMPORTANT! as it will automatically dump the SRAM data back to the SD card, which will be you BIOS dump)

3) Switch off and plug SD back into PC, copy all these files to the hard drive somewhere (desktop?) [might not work straight from SD]

4) find the .sav file in the SAVER folder on the SD card root and move it to the same folder as the previous step.
(Will be named the same as the file you ran on the GBA)
[Should be around 32kb, if not try the previous steps again]

5) Run GBABiosFixer.exe in compatibility mode, choose Windows Vista, then drag the .sav file to the opened window and press enter
(it should just disappear, but don't worry it should have worked, if you cannot open the file in a hex editor in the next step, then try this step again).

6) Then open the same file (.sav) in a hex editor [DO NOT DO THIS IN NOTEPAD, IT WILL RUIN THE DUMP]
(I used this free HEX editor from here: http://www.chmaas.handshake.de/delphi/freeware/xvi32/xvi32.htm )

7) Delete everything passed hex 3FFF (not including)

8) Rename to GBA_BIOS.bin (file size should be 16,384 bytes)

9) Enjoy your legally owned GBA BIOS Dump!!

    Apparently Nintendo adapted the 3D All-Stars emulator, instead of their old Virtual Console emulator - or, if nothing else, copying what fans have done.

    from what i can seem to gather there's some issues but nothing dramatic enough to severely impact what you're playing

    Start a new thread in the 3DS board, the chat box is not the best place to ask for such advice.

    I wonder...how would the gaming scene have changed had the Wii (and its bullshit motion controls and criminally neglected Classic Controller) failed?

  • AkiraKurusu @ AkiraKurusu:
    Microsoft certainly wouldn't have experimented with the Kinect, that's for sure. Would Nintendo have released something like the Wii U early?
    Gift
  • AkiraKurusu @ AkiraKurusu:
    That would've had a different name, so as not to tie it to its failed predecessor (something the Wii U dearly wished it has gotten anyway).

  • Veho @ Veho:
    PlayStation 2 already had that EyeToy thing before the Wii, and a whole lot of games supported it. Microsoft would have had something like the Kinect even if the Wii failed.

  • E1ite007 @ E1ite007:
    For some reason, some Amazon reviews said it was a scam 'cause it launch there before they made an official launch on their webpage...anyway, according to people, it's good...it was gonna be my first option to buy when I wanted something to farm in games automatically, but then I backed down since tax fees and shipping would have costed me a fortune to Mexico...
