Brazillian here. Thanks to this article I remembered the many bootleg games we had here in Brazil.
For example, we had this hack called "Futebol Brasileiro 96" (something like "Brazillian Soccer 96") that was a modification of "International Superstar Soccer Deluxe" for SNES. It had brazillian teams and translated menus and narration to Portuguese, however the translation was so broken that it was funny. A clip of this game: https://www.youtube.com/watch?v=b82MzyafDzg. I still play this game sometimes, because the narration is unique (it is more of a Spanish them Portuguese).
Another one is a hack called "Ayrton Senna Racing", modification of "Nigel Mansell F1 Challenge". This seems to be a much better hack, however I didn't play it when I had a SNES. The translation seems fine, except for the lack of accents in the words. Clip here: https://www.youtube.com/watch?v=UKeB1AXsUqY
Or this one, called "Omega Brazil '97", hack of my favorite racing game of all time: Top Gear 2. I had the original game, not this pirated version. But it is still funny (anyway, Omega was considered a luxuous car in 1997, this is why this hack used it). Clip here: https://www.youtube.com/watch?v=cJQkjHhc99M
The hacks are not limited to SNES however (the article even shows some "official" hacks made by TecToy for Sega Master System/Mega Drive (Genesis)). I remember various hacks for "Winning Eleven/Pro Evolution Soccer" (a game that was much more popular here in Brazil them "Fifa", at least until the PS3/Xbox 360 era). The majority updated team formations, translated menus to Portuguese, changed the music, etc. Some even included Portuguese narration, in some cases the sound was just ripped from live TV soccer games. An example can be found here (and it seems to be a recent patch, from this year): https://www.youtube.com/watch?v=7Fpv4nhcAfY.
The gaming industry is much better nowadays. You can find current generation consoles in local stores, with official imports instead of going to the grey market. There is even popular series (like FIFA/Pro Evolution Soccer, Assassins Creed and GTA) that has official translations to Brazillian Portuguese, including in some cases dubbing (the last Mortal Kombat is an interesting example since some people criticized the performance of one of the artists that dubbed Cassie Cage). The games are still expensive though, but Steam helps in this case. However I sometimes miss the old times.
