rom working in prev build are not working in new one

Hi everyone, thanks in advance for any help. I apologize for anything I am not understanding correctly as I am still new to this.

My goal is to put together a MAME arcade with just about 70-80 games mostly late 80s to 2000 era fighting games, beat em ups and shooters.

I have been downloading individual roms rather then a giant rom pack as I just want to concentrate on games I actually want and getting them running as smoothly as possible.

I am using the latest Launchbox and Bigbox which I just purchased in the last couple weeks.

I started by creating a build on my main Windows 10 PC just to test it out and start to understand how all this works.

I had a little bit of initial confusion but it didn't take me long to get all the games working that I wanted.

I then was able to obtain a spare PC I could dedicate to running Launchbox with MAME only.

But on my new build, with the same emulators, roms and other associated files I am having trouble getting 1/2 to 2/3 of my collection running. Again using what seem to all be the same files in the same config.

Most of the ROMs I am having trouble with are 90s era Capcom fighting games such as Street Fighter 3, third strike, alpha series, x-men vs street, x-men coa, beat em ups including AVP, armored warriors and even some random shooters such as Air Gallet. Also Mortal Kombat 1 and 2 (though strangely 3 works). TMNT. The non working roms just don't load.

All my neo geo aes roms seem to work. 194x shooters work, and many of my non capcom or konami 90s roms seem ok. NBA Jam works, Simpsons arcade works, Larger early 2000 games with CHD files seem to work including golden tee and nfl blitz. 

Again all the roms I have issues with I got working in my last build. I don't think any of them had CHD files.

I did install a MAME bios pack.

I am using MAME 172 64 bit. Again same as on my previous build.

I have been stuck on this for 3 days now so I am not sure what I am missing. I went to so far as to copying my entire directory structure and files from the previous build.

The only differences I can see is my pc it was working on was Win 10 64 bit, the dedicated mame machine is win 7 64 bit.

Any help or pointers would be much appreciated. I feel like their is some stupid little concept I am not understanding.

The problem with MAME games is that if you download individual roms, you don't know what version of MAME they were built for. Sometimes that wont matter, sometimes that will. At this rate, it might be easier to download a .181 rom set, MAME .181, run through the importer, then favorite the games you want out of the set, and have everything else as a bonus. Otherwise, I would say to match the same version of MAME your other PC was using, or try a few random versions and see what happens. The roms can all be from various different sets, the BIOS could be from a different set all together, etc. There's no telling. If you carried everything over exactly though... then I am little more confused as to what happened. Maybe @lordmonkus or @DOS76 know something.

Thanks, I am confused as well.

I went so far as to copy my entire Launchbox directory (which has the imported roms in its games directory) and my entire MAME folder.

Unfortunately when I did that all the roms stopped working.

I'm really at a loss. But thank you for your suggestions.

If LaunchBox is using relative paths (You can edit a game or emulator and if you see ../LaunchBox/, that's a relative path), then it can be moved to a new system easily. LaunchBox is fully portable, and if using relative paths it's just a lot easier. So if anything was using a full path (Which has a drive letter in it), you'd have to put those items on the same drive letter in the same path, or change their path to the new location.

2 hours ago, DOS76 said:

BIOS files are included in the newest ROM sets to find what you would need you would have to parse the MAME .xml files and search by game what bios files it may need

Yea, this is another reason why I said to just grab the set. All the BIOS you'll need plus more will be in the pack. If you grabbed the games individually and then grabbed a rom pack, they could all be based on different versions or incomplete.
