Easiest Way to Update MAME ROM Set??

lettuce:

Just wondering what is the best/easiest way to update an old MAME ROM set? I currectly have the full rom set of 0.144. 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)' ?

BadMouth:

no.  things will have been renamed and/or reorganized.  pasting in the new files won't account for that.
you need to use clrmamepro.
There are several online tutorials out there for it.

Also, I have found it is easier to not update mame with every update. Just update once a year or so and save yourself the headaches.

True dat.


Hmmm, a coherent and grammatical post from lettuce, but information that I would think he knows. Is Donald Sutherland around?

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.
