In 2020 GBATemp report one their members go jailed thanks to nintendo.It was the creator of freeshop.
Many times here on GBATEMP members say piracy its a problem of service and price.Nintendo delisted a huge dsi games from their eshop,theres no way to play those titles again.....well you play again those delisted games its to hack your 3ds.If nintendo its very smart they will have a ton of cash dont delist their games and everyone happy.
