Don't want to turn this into a MESS support thread as your RipOff is truly the star here, but off the bat, the best advice I can give is to start in a fresh new directory. Do not retain any previous settings. Go to command line and at 'C:\MESS>' type without the quotes "mess -cc".
This will create the default configuration file for MESS. New versions have HLSL support. If your graphics card cannot handle it, MESS may crash or have other issues. Find inside the mess.ini file that was newly created the following line:
#
# DIRECT3D POST-PROCESSING OPTIONS
#
hlsl_enable 1
And set it to:
hlsl_enable 0
Under the 'software folder' I have a7800.zip containing the BIOS file.
I keep my ROMS in a completely separate folder and do not use any MESSUI. Everything I run is via a front end which issues a simple command line to run a ROM. It's either that or I have my own batch shortcuts setup as icons on my desktop inside category folders. Command line examples:
d:
cd \mess
mess.exe a7800 -cart "d:\rni\atari 7800 roms\GLHomeHacks\Pac-Man Collection (Pokey).zip"
d:
cd \mess
mess.exe a7800 -cart "D:\RNI\Atari 7800 ROMS\Hack-Homebrew\Space Duel (Hack).zip"
d:
cd \mess
mess.exe a7800 -cart "d:\rni\atari 7800 roms\Asteroids (1987) (Atari).zip"
Etc...
I think you get the picture
Controller and driver (difficulty switch) changes are done after MESS launches, pressing the 'Tab' key. Of course you can turn on *.ini support inside MESS.INI and do some tweaking via notepad as well. I'm just trying to give the basics to get MESS up and running as quick and 'clean' as possible.
