Even if the figure has it differently, in-game it will still be pronounced as Goa Magara. "Goa" in Japanese, since Katakana and Hiragana are phoenetic, is still pronounced as "Go-ah". Capcom (and to some extent Nintendo as well, in the case of Fire Emblem names) tends to use unnatural Romanization in western releases that, in my opinion, is actually harder to pronounce than in the original Japanese.

The r/l issue is not really the same, since in Japanese the r is pronounced somewhere between the two, but can lean towards on or the other in certain regional dialects. A lot of foreigners just starting out with the language have a hard time pronouncing certian words because they tend to either use a full "r" or a full "l" sound.

Still, I do think this is the way the name would be written in case of a western release, though I have to state again that I'm not a fan of the name-changing, but it is better than a full change. I still think Nibelsnarf is the worst name ever.
