Reading XORO DMB

Open phimmerich opened this issue 2 years ago • 2 comments

I have a XORO receiver and i downloaded the channel list, the file extension is .dbm. I tried opening the file using ChanSort and got the following error: No configuration for .DBM files with size 109720 in .ini file I attached the file in question. Thanks HB_DATABASE_C.DBM.zip

I added experimental support for this format to https://chansort.com/ChanSort_2023-12-18b.zip

This specific version of the format removed the header containing the checksum, but there are a couple extra bytes at the end of the file, which MIGHT be a different form of checksum. I have not been able to reproduce that value with any known 16-bit checksum generator, so maybe it's not a checksum after all.

If the receiver refuses to import a modified file, it could be a proprietary checksum algorithm - and we're out of luck.
