SortInfo is able to export the game and control list to a text file. You can specify what delimeter to use, and you should be able to import that file into Access. I have done it before with MySQL.
1) create a file with mame's listinfo with something like:
mame -listinfo > sortinfo.txt
2) Run SortInfo.exe
3) File->Import->Mame List Info file (and select your sortinfo.txt)
4) File->Export->Argument Template File
select the file you want to save
enter a template. I think that the following will save all values, separated by a '~'
%A~%B~%C~%D~%E~%F~%G~%H~%I~%J~%K~%L~%M~%N~%O~%P~%Q~%R~%S~%T~%U~%V~%X
I was able to import this into a MySQL database. Hopefully you can do the same with Access. By the way, I couldn't use comma separated values because some of the data elements have commas in them.
