Oh I see! Can I unpatch the two ips'es from the game or do I have to redownload the rom?

Update: I noticed on the readme it said to use either xdelta or ips, I had already patched the ips files. However now the game won't load at all.

DeltaPatcher and DeltaPatcherLite won't patch my xdelta files. This is my log [15.37.04] Original file "Fire Emblem 4 - Seisen no Keifu (J).smc" selected. [15.37.10] Patch file "fe4_beta_7_for_headered_rom.xdelta" selected. [15.37.12] Applying patch, please wait... (don't panic!)
