You bought the DotEmu ports not the CodeMystics ones.

Despite your attitude and opinion regarding gog, you can ask for a refund for any game up to 30 days after purchase here on gog which is way more generous than any other storefront I can think of. Please correct me if I'm wrong.

Head over to https://www.gog.com/account/settings/orders and under the order #ID you should see a green shield indicating that the purchase is eligible for a refund. Afterwards click on View receipt or head down to contacts/support and ask for one.

On a side note Dotemu ports are often far from ideal, however you have also played Garou which is the CodeMystics port (the windows version only iirc), so I don't know what you are on about in this instance. Care to elaborate?

Guaranteed that they registered this account solely because they bought the Fanatical bundle and redeemed the games from it.

Unfortunately since you did not pay GOG money directly for those games, you won't be able to refund them through GOG. And since you revealed and redeemed the codes from your Fanatical order, you won't get a refund through them either.

Now you're left with a crappy attitude and regret for not exercising better judgment regarding your spending habits during a global pandemic. Imagine how much better you would feel if you took the time to research the quality of most of these ports before just dumping money on a bundle.

Not sure what system you're using but the release work great on my rigs. If you have the DOTEMU versions, you can extract the ROMS and use another emulator like MAME to run the games with some more features or on cab systems.

However, if you use Mame or Fightcade, you must find an up-to-date version of the Neo-Geo bios (neogeo.zip) in order to run it in either emulator, or else the games will not run.
