Just put what you can into my collection, also i collect obsecure multicarts for gameboy, not a lot of websites support the multicarts but ah well

Also some gameboy carts were released in both regions and have the same game id code so it does get a bit confusing.
Well aware of the usage of -EUR for European media. In fact, you'll find I'm probably the most knowledgeable person on the site when it comes to regional releases.

I'll see what I can do. Likely, this is going to take a lot of work/effort on my side to get the variants you have listed added to the database. Right now, I'm working on stripping out the games that aren't supported in our database right now, then I'll try to see if I can format it to import before seeing what has to be done by hand.
