Romcenter

Hi, I have two different sets of MAME roms with the same names which has been cleaned separately with ROMCENTER.
I want to know how can I combine bot set of roms into a single set since I know that some of the roms missing in one set are in the other set and also because, for sure, over 95% of the roms are the same between the two sets.
How can I combine the two sets into a single consolidated set of roms?
Thanks!

Hi there.

I assume you mean that you have 2 separate folders A and B, containing games from the same system, and you have "fixed" them with romcenter using the same DAT file.

If that's the case, copy all files from B to A WITHOUT overwriting any existing files. That way, any games that do not exist in folder A will be copied there. Then create a new RC database from the dat file and add both A and B folders as ROM folders in RC. Then simply fix folder A. Make sure to use fix options "rename files", "rename rom" and more important, "import missing rom". After that, folder A should contain a merge of all your games. Check if everything is OK by writing down how many green/yellow/reds you have in the "DATABASE\all games" branch, then remove folder B from RC ROM folders and check if something has changes in the color counts. If not, you're OK.

If that is NOT the case, please clarify.

Thanks, indeed, they are in two different folders but it's not a matter of "copy & paste" directly in Windows since many of the MAME sets are repeated but not the same (different roms inside of each set).
I will try this approach:

Make sure to use fix options "rename files", "rename rom" and more important, "import missing rom". After that, folder A should contain a merge of all your games


Thanks!

OK. A suggestion though. Keep a backup of all files (if possible), you never know what might go wrong...
