RetroArch Mess Core

[angelobodetti]

Hi All,

I prefer using RetroArch whenever I can because it is so easy and the controllers always work.

With that being said I am using MESS for Atari 5200, Philips CD-i and Neo Geo CD.

Anyone using the RA MESS core for those systems? I care more about ease of use than customization and settings.

Thank you!

Just use the MAME core it will work the same

[angelobodetti]

I tried the MAME core for 5200 and I just get a black screen. Any special settings I need?

[DOS76]

Do you have the a5200.zip in your system folder the structure should be like this ..\RetroArch\System\MAME\Roms\A5200 with the a5200.zip file in the folder

 

[DOS76]

I'm having trouble getting it to work too now I just use MAME personally for MESS stuff Atari 5200 needs a command line parameter its a5200 -cart

[angelobodetti]

I set up the folder that way and just a black screen. MESS opens and closes immediately. 

So you currently have 5200 working? What are you using? Also I unzipped the file and use the .a52. Should I rezip?

[DOS76]

I use MAME as long as you have the a5200.zip in your MAME set it should work using the command I mentioned earilier

[angelobodetti]

Regular MAME or the RA core?

[angelobodetti]

Doesn't work - MAME gives me an error "unknown system 'a5200'

This is nuts... I feel like most people have Atari 5200 working.

Ok got it! - I must've had a bad bios file. I have it working with MESS and downloaded 3 different a5200 bios files till one worked.

[DOS76]

yeah you must have an older mame set or not a full set if you don't have the bios in there

[angelobodetti]

It was a full set from PD (.173) but oh well. Thank you for the help

Also, try an updated MAME rom pack.

Even though RA has given me grief on the odd occasion I absolutely love it. I will most likely always use the standalone MAME for Arcade games but for most other platforms that are good with MAME/MESS like the 5200 I am wanting to start getting them to work with the MAME/MESS core through RA. I just wanted to ask how to structure it all. So far I have:

RetroArch > system > mame > hash > *all the .xml files*

The first platform I wish to get up and running is the Entex Adventure Vision. I have the bios for it which I named 'advision.bin' and placed it in a zip called 'advision.zip' as 'advision' is what MAME calls it. With that 'advision.zip' file do I place that in the system folder, the mame folder that is in the system folder or in the hash folder? I have actually tried it in all three folders with the mame, mame_2014 and mame_2016 cores and it did not work.

Do I have to put 'advision -cart' in RA's Default Command-Line Parameters, or Extra Command-Line Parameters after the custom config line?

So many questions!

Do not use RA Mame for non arcade games, it is a major royal pain in the ass.

Stick with the stand alone, it's much easier to deal with.

If you wanted to make me cry, you just succeeded.
