I finally got the chance to try what you suggested. I downloaded fink and wine but I am a little confused about it. When I double-click on fink it opens a folder with a lot of files that I cannot access and nothing else happens. When I click on Wine, it gives me three files. One file that says Wine and has a picture of a wine glass, another that says Readme.rtf, and one for Applications. I clicked on the one that says Wine but it didnt really do anything. Usually when I download a program, it takes care of the work by itself but in here I dont see what else I can do.
Also, since you mentioned it, I downloaded some parts of Seikai Houretsuden from other threads that were not named Fanbox but the results were still the same.
As for Jackin, I did try opening the .ccd and .img files by changing the formats and burning them into a CD but that didnt work.
When I double-click on the file with the .ccd extension I get the following message "There is no default application specified to open the document". For the .img extension, the message was "no mountable file systems".
