You need a clean, unmodified copy of Pokémon Mystery Dungeon Explorers of Sky. Patches are built against a specific version (usually the US v1.0 release) — other versions will fail the patch checksum.
Grab the patch from one of the download mirrors on this page. It will usually come as a .zip — extract it to reveal the patch file.
Open Floating IPS (Flips) or DeltaPatcher, load the patch file, then select your clean base ROM when prompted. The tool will produce a new, patched ROM file — keep the original untouched.
Download melonDS from its official site and install it. melonDS runs on Windows, macOS, Linux. Other supported emulators are listed below.
Open melonDS, go to File → Open ROM, and select the patched ROM you just created. Save files are generated next to the ROM — back them up if you're worried about losing progress.
Any of these will run Pokemon Mystery Dungeon Explorers of Heaven & Hell. Pick whichever matches your operating system.
Your base ROM is the wrong version. Patches are built against a specific release (usually US v1.0). European or v1.1 ROMs fail the checksum. Get the exact version listed in step 1.
Usually an emulator accuracy issue. Try a different emulator from the list — melonDS and DeSmuME are the most compatible for Nintendo DS hacks.
Most emulators write .sav / .srm next to the ROM. Make sure the ROM folder is writable (not Program Files on Windows). In-game saves are portable; emulator save states are not.
Yes — the emulator list includes mobile options. Patch the ROM on a computer first, then transfer the patched file.
