Problem with Sega Game Gear

[Bumpfi]

There are a view problems. first i loaded the game gear database in clrmamepro and created a new Folder with the roms (copied from no-intro set) but i recognized there are a view missing roms (most japanese). so i opened up the XML file to take a look but all looked good. I decided to copy and rename the roms by myself and put them in the roms Folder. i started hyperspin and the games are listed but if i try to start them a error massage pops up "Missing Extension in ini file" What should i do?

Check the extensions of your roms, are your new ones different from the rest?

If they are archived is the extension inside for the new games different?

If you are using Rocketlauncher you may need to add said extensions or your default emulators known extensions.

You can copy the entire Rom Extension contents into a notepad and search for your extension. If not found add it/them in separated by a | of course.
