Easiest Way to Update MAME ROM Set??

<< < (4/4)

brad808:
I update my mame version every time I format my cab computer, which happens to be this weekend. I never bother updating previous rom sets though I simply download a new full set. In the day of terabyte hard drives and high speed internet I can't be bothered messing around with old sets. I just start to download the new set before bed, wake up in the morning and delete the old set.

I have downloaded torrents of 'MAME UPDATE ROM SET (144 to 145)' and 'MAME UPDATE ROM SET (145 to 146)', can i just copy the files from the 'MAME UPDATE ROM SET (144 to 145)' folder and overwrite any files windows asks me to in my main MAME Rom folder, and the do the same again for 'MAME UPDATE ROM SET (145 to 146)' ?

This may be really lazy of me, but I basically did all the stuff with CLRMame and all that once, ages ago, then got sync'd with a torrent of the full set.  Periodically I got back and get the new torrent for the latest version.  Roms that have changed won't match the checksum for the torrent so will get scrapped and re-downloaded.  Files that match, will just get seeded.  So I let the torrent handle whatever changes were made.   Seems to work ok.  You should only get the changes then and not have to worry about the "update" torrents at all.   Also, you're contributing to the torrent by allowing it to upload the files you already have while you're downloading other stuff.  This has the added benefit of possibly giving you better transfers since, if I recall, torrents give preferential treatment to those contributing more to the torrent?  I could be wrong, but however it works out... it should mean that you're only downloading the files that changed if you queue up the full rom set torrent instead of the updates.

Updates should work too though.  In theory, an update set should have whatever changed.. not just new additions.  But it's possible that things weren't included that should have been.  Doing the full rom set torrent guarantees (assuming the torrent is correct and properly CLRMame'd and all that) that you have the proper files for that version.

This would be the best way to do it, but not sure how to sync say romset 0.146 with the torrent so when 0.147 come out i do what, just tell the 0.147 torrent to save to the same directory where romset is 0.146?? Surely it cant be that straight forward?

Wouldn't doing that method leave you will all the old out of date files as well though? Combining torrents i would think would download all the new files of anything changed but it won't delete the original files that were updated or renamed.

Yes.  You only download the rooms that don't match your files but out of date rooms are not removed.  Over time, you will end up with a lot of junk.  Clrmamepro will it either after each update or whenever you want to do it.

Or flush your roms every X number of releases/downloads and grab the torrent and start all over whenever you want.

No need to update if they aren't adding games that you want to play IMO. And no need to do any of it if its only a few games.  Run multiple versions of Mame with a few roms for each version.  Much easier and less hassle.
