idk if FF2 has decapitation head gibs disabled, but:

decapitation on a custom model can be done by renaming the head bone on the model's head bone to bip_head, and thats it.

there are sequences for headshot and backstab, so you can change those with a custom model, but it is impossible to set an animation for a ragdoll on death (strictly with models, maybe with a custom plugin)

with AE_CL_BODYGROUP_SET_VALUE, you can change what bodygroups are shown on the model on a particular sequence, so you can change what bodygroups are enabled/disabled on the ragdoll sequence, if you want.

hopefully that answered your question, sorry if it didnt
