[Help] Fim Speedway Grand Prix 15 - .rpack archive

[Jumperooo]

Hello,
Sorry for my English

I wanted to edit textures in the game in which I mention in the topic
but the obstacle for me is the RPACK format (same as in Dying Light)
but when i try to extract it i only have 3/4 .dat files

There is an old topic about this format, have you checked all the suggested solutions there?
