Currently making a GBA Pokemon ROM Hacking tool, any idea what's wrong with this code? (C#)

[Momoro]

Hello 😃

I recently revisited an old project of mine called Advance Edit (no idea if that name's taken 🤔 hope it isn't!), and I was going to make a sprite editor, but I've hit a roadblock 😕

I program mainly in Windows Forms C#, so this is the code I wrote:

BinaryReader br = new BinaryReader(File.OpenRead(filename));

br.BaseStream.Seek(0x728B04, SeekOrigin.Begin);

byte[] bitmap = br.ReadBytes(Convert.ToInt32(br.BaseStream.Length));

Bitmap myBitmap = new Bitmap(new MemoryStream(bitmap));

pictureBox1.Image = myBitmap;

br.Close();

It should work to get the image from the ROM, but for some reason, it doesn't.

The image I'm trying to get is Bulbasaur, and from a Firered ROM.

Any ideas? Thanks 😄
