Just in case some one wants to know; few months ago i talked with the "main man" of TEG via facebook, who sadly said he lost everything of the work of the xmen vs street fighter II of SNES due his hard drive die. So, everything left is that magneto vs dhalsim portrait screen... and that's all.
That's how also a lot of other works for SNES and other system where lost, too. As the Saint Seiya games for SNES.
