Gamebox64 is written in Perl and using the CGI module (which is a rather old module for web type things like getting in queries and printing html, it's what I used back in 1999 when first using Perl).
It seems the CGI module isn't included by default in Perl 5 now and thus I can't get the scripts running easily on my new hosting.
There seems to be ways around it by installing the module locally etc. but I think at this stage I might as well just rewrite the site in PHP, there's not too many pages and it shouldn't be doing anything too complicated.
So it'll take me a little while to do that no GameBox64.com for a few days
