Hi and welcome
We can't host anything before it is checked, even if it already seems obvious it is abandoned. Please post new topic in
Requests forum and put name of CD release as title and put other info like company and year in text. You may add your opinion on why you think it is abandoned and our guys will check it.
As for uploading ISO, just upload it to any file sharing site and post the link(s) in ISO Cellar in topic
Requests. I'll handle the rest.
That is enough, but it would be helpful if you put some extra effort. First, pack the image to take less space. Use zip, rar or even better 7zip (best compression) for that. Then, when posting a link, add type of image (ISO, BIN etc), the size of compressed archive in megabytes and any additional information. That can be: what games are in the release (if more than one game), any extra material possibly included, what release of the game etc. In your case, I guess the game is called Jazz Jackrabbit, Epic Classics release.
If you are unsure which site to use for sharing, we tend to use 4shared. You need to create an account there, but it is free and you get some space where you can host files indefinitely. And trust me, that's really important, since previously we had to bother with re-uploading constantly.
BTW, is the game any different from the original version?
