For those not familiar with DOS kernels, that's an internal NLS table that should be present in every DOS kernel.

Try to decompress it if you can, to see whether you're right or not. I bet you'd fail, but even if you succeed, you'd surely see that they don't match at all.

For any problems, flames, suspicions, etc. regarding LZ-DOS, please turn to SPS who released it (see their site for more information), not to me!
