Can you use the same romset with 2 different versions of MAME in Mamewah?

[slapaham]

I really want to set up my Mamewah so that I can play my romset in both the new and old versions of MAME. This would allow me to use the best version of MAME for each rom and see a direct comparison.

However, coming to setting up MAME V56 (which I named it) and pointing the ini file to the rom path used by my other version of MAME, it doesn't display any of the games.

Is there some confliction somewhere? Is this actually possible> (I don't see why it wouldn't be)

Any ideas why this isn't working for me?

This already give you problems cause different MAME version might require different/changed/removed/added/FIX  etc...  ROM SETS.





Anyway, there is a way to setup FE to use different version of MAME and just make sure your ROM SET matches the MAME version its running.

It's possible to have 2 different version of mame. Even on the same list.

Well, I have v.122 romset and I've tried running some of the games on v.0.56 MAME and quite a few work. So I started to generate a list of games that worked in 0.56 for Mamewah. However, when I generate a list in Mamewah only some of them then run from Mamewah. I was thinking, might this be because the files within the zip files conflict with the structures given in the 0.56 dat file I have? And if so, how would I get around this? Would I have to edit the dat file to follow the details of the zip files?

Hope this makes sense and isn't totally gibberish!

Just out of curiosity , why do you want to use one rom set for two mame versions that far apart?  There are going to be a ton of games that Mame .56 will not run.  Why not have two different sets of roms so you can run them all?   Mamewah can handle two different Mames each with its own romset.

Ya what he said. Just seperate the roms.

[northerngames]

yeah if you do them seperate with their own matching parts on each like they were other emu's you could run as many versions as needed like mame1 mame2 mame3 etc.

Thanks for the response guys. However, as I said before, there are games that will run in Mame when I run them out of Mamewah but when I try and load them through the Mamewah menu system they won't load.

This indicates that some of the roms change as the only reason I can think they won't run through Mamewah is that the .dat file I'm looking up the information up from doesn't match the rom structures in the zip files. Does this make sense?

The reason I wanted to run more than one version of MAME is that the PC I'm using in my cab isn't the most powerful and therefore won't run newer versions of MAME very well. However, rather than delete it there are a couple of games that only run on newer versions that function okay that I like that won't run older versions.

Cheers for your feedback.

yeah just name mame version whatever mame1 and mame version whatever 2 as mame 2 like it were two seperate emu's and then make them both lead to the same rom path and you will have the same list on both list on either version you used.


more then likely that is the problem is the roms dont match the version your using but the above method would work and you could name them whatever you wanted.
