EPAC4???? ( Problem with importing wrestlers )

[TokyoTokyo]

Hello everyone, trying to import some wrestlers, I have come across files that in HxD have this format, and it is precisely with those wrestlers that have more than one fighting suit, or an entry suit, I have opened the PAC first in X- Packer 10 (an old version, since I do not have to buy the latest version) and it appears only to inject the ring suit, and the entry suit appears almost unformatted, and when injecting a PAC into such a file and then Update Arc Throws me an error. Also try to pass it to EPK8 but when opening it in X-Packer the file that should be the input suit appears rarer, and in PAC editor it appears as a .DAT file.
Please help
