Don't start repacking IFR like games right off the bat.
lzma uses FAZip32.exe which is not present in your folder.
lzma needs to be set in arc.ini before it can be used.
open your arc.ini:
Code:
[External Compressor:X]
header = 0
packcmd = X.exe e {options} <stdin> <stdout>
a basic structure is like this. You can't learn it all in one day, just keeping compressing games until you evolve and don't use commands as a beginner, use something like UltraArc or DiskSpan as a beginner.
