Gah! >.<

Alright, I downloaded a couple GBA-ROMS right? I have the files for them on my desktop right now still in the .rar format. How do I get them to play on my VBA?

Extract them using 7zip or Winrar.

And they will automatically be converted to .gba files?

the .gba files are inside the .rar files (think of .rar as a filing cabinet). Extracting will get the original .gba file out from inside the .rar

Remember VBA supports loading GBA ROMs from only .zip files I believe, although dragging and dropping a .rar file on VBA might work too. If you have any problems playing them, see https://www.romulation.org/forum/index.php/topic,6326.0.html
