It looks like my problem was Peazip. I went to your sight and downloaded Pinboliada as a zip file. When I opened it with Peazip it didn't show a gamedata folder. However, when I opened the same zip file with Explorer it showed a gamedata folder. 
I couldn't look at the tar files from ibp with Explorer so I was relying on Peazip to tell me what was there. Now I'm thinking that if I find a different tar extractor I will find that the files I downloaded before have gamedata folders as well. I don't know why the crap Peazip doesn't show the folders but it isn't. 
Just a final confirmation. I downloaded a copy of 7-Zip and reviewed the tar files that appeared to be incomplete in Peazip. Each of the tars had a gamedata folder that wasn't showing up in Peazip.
7zip is good. I use winrar to decompress all my archives and for the arcade games I use winzip to compress them.
However, winrar will not compress files into tar, for this I would use 7zip but I prefer to compress my arcade games in zip format (my preference).
In fact, the download option in my arcade does this automatically.

You have confirmed that you have the proper files for these v32 games but for some reason your arcade is not presetting these save types properly.
The only time I had this problem I fixed it by uninstalling my arcade (and deleting its files from install list) and then installing it again.
I am guessing that there may have been flagged errors during install that were not manually parsed. This means the arcade is possibly missing an edit to a file that it needs to function properly.
Do you remember if the arcade installed properly without flagging any errors? You can try what I mentioned above and if there are any editing errors, you must do those edits manually.
