Making the image crisp

[Davoo]

I'm looking to have the display be sharp, and not blurry. I'm even okay with the pixels getting slightly messed up in exchange for crispness. My understanding is I can achieve this by turning off bilinear filtering, and/or by changing the 'prescale'.

I've seen a number of different forums and questions about these things, but because this software always changes, I TRY to follow the steps provided by these old guides, but I don't think it's working. So I figure this would be a good "fresh for June 2015" thread on crisp display in MAME

To turn off that filter, edit mame.ini with notepad, look for the line that starts with filter, and change the number from 1 to 0. That will give you sharp crisp pixels.

Edit: I found a place to get an updated ini file. I don't know if this place is common knowledge, so here:

Hmm my ini file doesn't have a line that starts with filter. There are two things that have Filter in the name, and changing either of them doesn't work. The ini file I'm using is actually a slightly older version than the mame software itself. Yeah, I'm kinda surprised the software works fine with that. But for whatever reason I couldn't get the config file to be created, whereas I COULD make it work with an older version. So I just copied that file into this one. I'll look for a place to just straight up download the 0.162 ini file.

describes the filter option.

You can use the -nofilter option to turn it off, seeing as you can't see it in your file.



create a new mame.ini
>mame -cc

edit mame.ini, look for filter, turn 1 to 0, save the file, all done.
