Hi, can anyone help me pls? I cannot patch this rom to its base rom
Hi Hien, thanks for coming here. You may check our patching guide here https://www.pokemoncoders.com/apply-ips-ups-patch-play-rom-hack/ or see this video https://www.youtube.com/watch?v=M3RnlWQWDHQ
I dunno if this page is still active but where do you download the compatible Emerald ROM to be patched with the UPS?? I had a pre-patched ROM once but I lost it just recently and the websites I’ve went were all now gone. I’ve tried patching it but it all doesn’t match with all my current Emerald ROMs. I hope you can help me. Thanks in advance.
Hi there Snow Hasegawa. Unfortunately, we don’t share information about roms. The reason those sites you know that you’ve been getting your pre-patched files before are now gone is that they share rom files. It’s illegal to share rom files and considered piracy.
Well that’s really useful isn’t it
I Just download this because you can run indoor
