I have been reading through much of the posts and information on the web but have been unable to get the mame64 (0.185) program to load an Atari 2600 cartridge ROM. I have a couple of old cartridges I want to show my son but the 2600 died years ago.
My discussion will use the ROM Asteroids since this is one I have.
I launch the MAME64 GUI and scroll to Atari 2600 (NTSC) and select it. I then have a new list of roms of which Asteroids is listed. If I select it, I receive an error that the ROM is missing files. I know the ROM is good because I can get it to load if I use a command line to run the 2600 console manually. The MAME64 gui just cannot find it.
I have little understanding of XML but have done my best to review the a2600.xml in the hash folder. If I understand it correctly, I should have a zipped file called asteroid with asteroids.bin inside. This where I get lost. What folder do I put the zipped file in? From my reading, it should be in a folder called a2600 and the folder or subdirectory should be in the folder ROMS. Although I have searched everywhere I can, I come up short of the answer to this. I have tried placing the ROM in \software \software\a2600 and \roms\a2600, the ROM is never found.
Can someone offer some assistance in my understanding or point me to documentation I can read to solve this?
