+Atomikwave will test the trad files soon on his custom pcb guys. Real badass job yep, he confirms that previous original works great on it.
It’s still a work in progress...

My memory could be wrong but I believe in the interview present on the collection or some other interview the director said the fatalities were restored but I'm not 100% sure.
It's actually the other way. They said that they removed the dismemberment sprites/animations to make room for the Story assets. From what it appears to me, seems like they used Special's 2nd "less censored" AES release as it's base, as all the Overkills seems to match up with FE/Perfect, at least from the ones I've seen. I can't help but to feel the loss aversion after playing Special for so long. The "Story", while nice if not lackluster, just doesn't matter as much as seeing someone get split at the end of an intense PvP. The balance changes are minor (still waiting for an change list), and it was made for players back in 2005 which at this point everyone has moved beyond that after 15 years of Special. I do however appreciate that this lost Rom is finally available for everyone, as well has the hard work everyone has done to port the English text into something that original hardware can run.
What happens if you turn the cheats on for fatalities in the unibios using the new rom?
Fantastic work.
If I’m not mistaken, rom sharing is not allowed here. I would remove the link my friend! Please correct me if I’m wrong!
