Ripping sprites from Islands of Wakfu (XBLA)

[ebonysable]

Alright, I managed to get libwmf working - it turned out it only runs on the command line. However, whenever I try to open one of the APM files with it, all I get is an error that it isn't a WMF file. Even on the files that I've changed the file header and the file extension to be WMF! I honestly don't know what else it could be looking at for the file type - I was expecting at the very least to get some sort of corrupted image out of this!

This is what happens when I use libwmf:
C:\Program Files (x86)\GnuWin32\bin>wmf2svg.exe Fx_fish_scale.apm
ERROR: ../../libwmf-0.2.8.3-src/src/meta.c (179): wmf_header_read: this isn't a wmf file

C:\Program Files (x86)\GnuWin32\bin>wmf2svg.exe Fx_wakfu_colibri.apm
ERROR: ../../libwmf-0.2.8.3-src/src/meta.c (179): wmf_header_read: this isn't a wmf file

C:\Program Files (x86)\GnuWin32\bin>wmf2svg.exe Fx_wakfu_colibri.wmf
ERROR: ../../libwmf-0.2.8.3-src/src/meta.c (179): wmf_header_read: this isn't a wmf file

Does anyone have any ideas?
