Updating mame roms

What rebuilder does is take rom files from the source directory, sorts them out and save the new file into the destination directory. If you have a complete set of MAME roms and a new update comes out.

Once you've downloaded the new roms you can use the rebuilder to look in the folder where the new roms are and create / fix sets of roms in your MAME folder.

The conventional way to update Retro Pie and install new features is through the setup script.

The setup script can be accessed from the Retro Pie menu in emulationstation.

The core components needed for Retro Pie to function are: You can update/install and remove packages individually.

When selecting a package there is also a help guide with extra information specific to that package: Package Help: The Package Help for each emulator should show you: If you are worried about conflicts during an update you can always just start with the latest fresh sd image which can be downloaded here and just copy all your files back over onto that instead of updating from an older image.

1) Loaded 0.138 set and dat, verified good 2) Added 0.139 DAT, clrmamepro recognized it as an update to 0.138 and asked to update, I said yes.

3) Added the 0.139 update folder to the add-on path 4) Did a Diff scan, fix all errors 5) Rebuilt using add-on path 6) Rebuilt using backup path (doesn't do much, I think it does this in step 5) 7) Use scanner, using the 'Scan'.

MAME's purpose is to preserve decades of software history.

Also, using the 0.138 set and updating to 0.143 or 0.144, I have 100% but after that, the total existing rom count practically doubles (200k ) and I never have the full set. A dat file for Clr Mame Pro you can download the 0.149 dat if you don't have it listed under Mame Dats, P. that site also has some of the art work and snaps and other great resources for mame P. extracting the packs before rebuilding is going to be the quickest option but it still takes an age P. I actually downloaded the sets myself from here, done that yesterday and today, managed to get every single rom that way If you run through the process again try extracting each set and update to it's own folder, rebuild from each folder alone just in case something messed up via the other rebuild 7349 is a rather large amount of sets to be missing :/ Also when you scan make sure all the fix options are on, otherwise it will not fix and miss named sets or roms and any other fixes.

The sets I got are 0.138 through to 0.149 that got me my full rom set (obviously this does not have CHD's or Samples) if any missing between all those you will of lost out on some roms that way Clr Mame Pro is the best for scanning the roms Romcenter is best for organizing roms though, it is another dat tool, you should be able to import the dat, or the Rom Center web site may have that dat in Rom Center format It has been a very long time since I felt the need for Rom Center, I used to use that as a front end though because it lists all the roms in the prog and you can run them from it (you just config the emulator into the settings) Anyway the point is Rom Center lets you set your own filters, so you can make it just show Jap only games ect, not sure how well that will work with Mame roms though, if that works ok with mame roms then it is a simple case of filtering so it shows what you want rid of selecting all and deleting...

- Manually copy all files from 0.140 and 0.140u1 rom paths to 0.139 (your master MAME folder).

The Rebuilder The rebuilder is an advanced way to re-create rom files and find missing rom files without having to download them.
