A 5-step guide to getting Pokemblem running on Game Boy Advance , including patching the base ROM with Floating IPS (Flips) or DeltaPatcher.

You need a clean, unmodified copy of Pokémon Fire Emblem: The Sacred Stones. 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 mGBA from its official site and install it. mGBA runs on Windows, macOS, Linux. Other supported emulators are listed below.
Open mGBA, 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 Pokemblem. 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 — mGBA and VisualBoyAdvance-M are the most compatible for Game Boy Advance 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.
