I'm looking around Senran Kagura Estival Versus for the PS4 and the tpk script I've made on the Vita vesion work on the PS4 version but I think the rip files of the PS4 version is somewhat compressed.
I've tried comtype_scan2.bat/comtype_scan2.bms to no avail.
[Edit] Just realized I could skip comtype_scan2 when it gets stuck uncompressing by pressing ctrl+z then chose not to cancel the process and found its compression is NISLZS.
The 1st 8 bytes seem to contain the decompress size and compressed size.
