I am currently using MESS with Mamewah for SNES and TG16 and it launches beautifully. It will not, however launch A7800 or A2600 from a frontend. I have tried using both Mala and Mamewah. I have confirmed that I can launch manually from the command line with no problems. I would imagine there is something wrong with my configuration somewhere, but the puzzler is I can get some systems to launch and not others. I also get the same results from two separate frontends. Then the fact that they all launch manually from the cmd prompt maddens me even more.
Using a FE (doesn't matter which one) I get the following error. This one is for A7800
Fatalerror: Device Atari 7800 cartridge slot load failed unspecified error. This is displayed briefly in the dosbox and the mamewah goes back to the menu.
Here is my Mamewah Atari 7800.ini
Any help would be greatly appreciated.
