GIF
JPEG
As you can see Neo-Geo screen shots that are JPEG compressed don't look as clear as GIF. GIF is limited to 256 colors which works well  with Neo-Geo games because many don't show that many at any one time. JPEG can support 32bit color, but you are sacrificing image quality in the process. The JPEG images are also bigger in file size (sometimes double the size for the same screen shot as GIF). So that is why I went through and have redone this entire section in GIF format.
