Hello, i have a problem trying to run the atari 7800 with MESS.

I am using the version 132b in windows xp and each time i try to launch a game, with the command "mess a7800 -cart c:\rom.a78" i obtain the error code "7800.u7 NOT FOUND" and the execution stops.

I have created the mess.ini with the -cc parameter an i have the bios file 7800.rom in the Bios Folder. Any ideas? smile

Thank you in advance.

Zip the BIOS file as 7800.zip and put it in the folder.

The error say 7800.u7 not found not 7800.rom this maybe cause the problem.

Note that the former "bios" folder is now called "roms" - just like in MAME, maybe thats the issue.

yeah, i have my bios in the roms folder as 7800.zip and a7800.zip (I also tested with each of them separately).

i have tried a fresh install without the bios files and without the mess.ini and i get the same error, could somebody try to run a game without the bios file to see if you get the same error? please.

7800.rom, is it supposed to be called 7800.u7?

if it's zipped in a7800.zip file (inside the roms/ folder), the name does not count because MESS loads by crc
