I am very doubtful that it's crashing. What's far more likely is that you're not running it properly. Double-clicking the *.exe file won't work. You need to feed it the correct parameters/options/whatnot. Open a command prompt, browse to where you have the *.exe file, and run it from within the command prompt. Usually, this will tell you what arguments it expects to see, to get it running. Once you've done that, read the output.
Alternatively, if it comes with a Readme.txt or a ReadMe.1st file, or something, read that, and it should tell you how to use it. Hope that helps. Mouser X over and out.
Alright, I figured out how to run M1 from command prompt, so I typed in m1.exe jpark. At first it seemed to be working, but then it said ROMs not available, "jpark.zip". So I put the zip archive in the folder and titled it jpark along with the rom. It still comes up ROMs not availabe, "jpark.zip" and then Aborting ROM or something like that. So now what am I doing wrong? My guess would be an incomplete file (part of the file is missing) but the rom runs fine in an emulator, except M1.
Okay, still won't work. I did what you said when I renamed the ROM, so now it won't work. I'm not sure how to check the CRC, but that's most likely the problem.
