>>56941505BDSP is like the GTA Trilogy pre-update. It makes it available in HD on modern hardware, but it was an extremely rushed overpriced remake with glaring issues and bugs that was arguably worse than the originals in a number of ways. Except the GTA Trilogy gave you three games on one cartridge and BDSP gave you two games on one cartridge but only let you play one of them, meaning you had to buy the other one for its content.
It's a really pathetic state for Pokémon which had historically done far more for remakes.
