VisualBoyAdvance-M

You need:

Nintendo DS / lite - NOT DSi

1. Slot 1 flash cart

2. Rudolph's GBA Backup tool: http://rs481.rapidshare.com/files/274901332/GBA_Backup_Tool_021.zip

Steps:

1. If your flash cart does not support auto-DLDI patching, patch the GBA backup tool manually

2. Copy GBA backup tool to flash cart

3. Execute GBA backup tool

4. Insert your GBA cartridge into Slot 2

5. Press A

6. Press R button twice to switch to ROM dump mode

7. Press B button to dump cartridge ROM to gba file

8. To dump another game: Press X button and start rom step 4

When you are finished, your dumped gba files are in the 'GBA_Backup' folder on your flash cart.
You can then play your GBA games on your PC using VisualBoyAdvance-M.

Using the same tool, you can also dump your save data from your original GBA cartridges. These can also be used with VBA-M. The tool even allows you to write back save files to your original cartridges.

Dumping a 16 MB ROM takes less than a minute IIRC, smaller games dump faster. You can dump your games one after another without need of a restart. You can later transfer them all at once from your SD memory card to your PC.

What exactly do you mean with "WiFi"-Method?

he means he likes the ban. :P

Hm, I was a little suspicious, but it made kind of sense what he said :D

yeah, its a new type of spammer thats getting around atm.

Mind if I add a few more details? It was a little rough getting set up for me since it's hard to find a complete, clear guide on this stuff.

I used the R4i card.

1. Download GBA backup tool and R4i kernel (my card was the 2016 version, but at the manufacturer's website it only has the 2017 version of the kernel, it still works)
2. Unzip both, copy them to SD card, only r4.dat file can be in the base/root directory of the SD card, all the rest should be in their respective folders

Wouldn't work when GBA backup tool files were in the root of the SD card. Keep them in the GBA_backup_tool folder
