- Day-Care and breeding: deposits, withdrawal pricing and growth, compatibility, egg species, DVs and moves, DayCareStep, egg collection and the Odd Egg, compared with the cartridge's routines. - CountStep: walking happiness, DoEggStep, DayCareStep and DoBikeStep in the original's order; HatchEggs with the ROM's hatch animation, compared frame by frame with the original. - MAIL: all ten stationery types and the Portrait MAIL picture, compared with the cartridge's tilemaps, graphics and palettes. - Printing: Bill's PC boxes, Pokedex PRNT, MAIL and the Photo Studio take the original's absent-printer path. - Hall of Fame records (saved apart from the League flag, ready for the League to call) and the Hall of Fame PC, compared with the cartridge's _HallOfFamePC on 255 pages.
