Help with unknown compression. Maybe LZMA?

[twisted89]

Hi,

I'm currently making a file extractor for a game archive which has both uncompressed files and compressed ones and I'm having trouble working out the exact type of compression. The header appears to match a LZMA header but every LZMA decompression tool throws an error.
If anyone could take a look and share your findings it would be very much appreciated!

Thanks.

Here are some of the compressed files in a rar archive:

Edit: Never mind worked it out, it was indeed LZMA but the output size had been removed from the header as it was stored in the archive TOC.
