GMS1 version

Probably works in GMS 2.2 too, but I have no reason to check.

You’ll want to import the “gif_preinit” script from the demo project, which contains 50-something other scripts inside.

In GMS1, both helper extensions (gmv_array_magic and buffer_set_surface_fix) are obligatory because that’s old and buggy.

In GMS2, you can replace gmv_array_create calls by regular array_create or import the gmv_array_magic extension.
