I feel your pain.
I made a simple 2600 program once, just to say "I did it!" then went looking for a way to make one cart. Eventually found someone, but he had a reputation for selling other people's games and not sharing the profits, substandard quality, etc. However, this was all based off events from years ago, so maybe he changed. I decided to give him a chance.
He was very nice and helpful, and a real pleasure to work with. Then I got my game in the mail.
New atari games are made by recycling old shells. I understand and accept this. However, I would think most people would put forth the effort to remove the old label before sticking on a new one. The new label had perfectly square corners, not rounded like most atari games. Because of this, it didn't take long for the new label to peel up. He also put his company logo on the label. None of this is a huge deal, but I wish I had known in advance.
Most frustrating of all, the new circuit board somehow didn't fit properly in the shell- that's the best way to explain it. You know the little protective dust cover? It didn't line up with the board properly. I had to jam the cart repeatedly to get it to fit in the console. Eventually I got tired of jamming the thing and donated the game to Goodwill.
On the plus side, the game worked as promised, so I sorta got what I paid for. I never complained but I never went back.
No, I will not give his name, even if you guess correctly. Buy a supercharger instead.
Does anyone else out there make games for homebrewers? I'll be a customer.
