Most horribly translated SNES and GBA games.

[spotanjo3]

For me: Mega Man & Bass GBA had a horribly translated. And for SNES - Mega Man & Bass hacking translated was closer accurate but not perfectly translated.

The Breath of Fire games come to mind.
The GBA ports re-used the SNES translations without fixing any of the problems present, as I recall BoF1 has an instance of telling you to travel east when you actually needed to head west, or something.

https://legendsoflocalization.com/breath-of-fire-ii-super-nes-localization-review/ is a surprisingly in-depth review of what went wrong with the localisation, provided by none other than Clyde Mandelin famous for his fan translation and localization of Mother 3.

Of course, there's the fan translation of the SNES version of Breath of Fire II that goes above and beyond on a technical level so that a proper script can be put in.

Wait a second... who stole the title I used in my "Most horribly translated NDS/3DS/PSP games" threads?
