You could apply a clock patch with GBATA: http://www.no-intro.org/tools.htmCan someone tell me how to fix this please? I'm currently playing on an Ezflash iv and I chose riolu, so I need to fix this so I can evolve him
the Ezflash iv does not have rtc(real time clock)function.your best bet would be to open your rom in YAPE (yet another pokemon editor)and change how riolu evolves.
edit heres a patch i just made;apply it to a clean pokemon EMERALD rom;use a ups patcher to patch
Riolu now evolves at level 20 with this patch
