I downloaded this NSO snes games pack once that came with a lot of games but a lot of them were translated to russian or brazilian. I didn't even needed those because I understand english, but alright.
Then me and my cousin started playing E.V.O. and the text formatting was just horrendous. There were many times where you simply couldn't understand what was being said.
In order for those roms to work in the NSO app they need to be converted to a specific format, and the only convenient way to do that was to resort to a cryptic software. After many tries, it didn't work.
Then I had it! I opened translated rom that was in that weird NSO format directly into a hex editor, identified where the game code began and replaced it with the code from the original. Worked like a charm!
To rub salt in the wound,
a good brazilian translation of EVO do exists. They just didn't picked that one.
