Question for all the MAME + PI experts.
I had a premade image I was using in my Punch-Out bartop.
I loved it, it was super clean, well designed, had great background music, etc.
BUT it would not save my MAME configuration. Whenever I would exit a
game the config would be lost. I attempted to locate and modify the CFG file.
But I was unable to fix the problem.
So fast forward...........I decide I'll do a scratch build.
I download the latest version of RetroPie, and I was able to extract
all my existing ROM files from my previous build.
With some great videos from MLP and ETA Prime I was able to make some tweaks that I wanted.
I added scanlines and got everything to display in widescreen (I'm OK with the stretch).
I was able to delte the loadscreen text and got everything scraped.
Now to the issue..........I notice 3 versions of MAME in the emulators.
MAME Libretro, MAME (I think MAME 2003?), and MAME4ALL.
I'm unsure of what particular ROM set I'm using as I simply extracted it
from my previous PRE-MADE Pie build. So with that said, I'm unsure of
which version of MAME I should be using ?
For what it is worth, I've copied the files in two locations. MAME Libretro &
MAME4ALL - MAME Libretro displays as I'd like with the scanlines, etc.
MAME4ALL will not display as such. Does it matter which version I use ?
Will one give better performance ? I'm new to this, so any help is appreciated.
EDIT : I have another question. Looking online I seen a few videos where people made changes via the Retroarch menu, I recall it being some green menu for what it is worth. When I'm doing my configuration in MAME for my controls, do I do so via TAB (then entering my settings), or is it better to make the changes via the Retroarch menu ?
Thank you all
