Well, it's possible that there's a problem with the ROM you are using. That could cause the behavior you describe. There was another guy that had a similar problem with a game before. We were able to fix it just using a different file. I don't know what happened, but I think part of the ROM was bad. It could have been a glitch while writing to the cart. It could have been a glitch that caused some sector to get erased. I don't know. We fixed it pretty easily once we tracked it down.
Could you please try these things.
1) Take the AA batteries from when Faselei failed, and use them to play Sonic again. This should tell you if the batteries are truly dead or if it's some other glitch.
NOTE: I think you're saying you already did this step with Biomotor.
2) Use the Linkmasta's "verify" button to compare the Flash Masta cartridge with the game ROM you wrote to it.
3) Use the Linkmasta to make a full backup dump of your entire Flash Masta cartridge and email it to me. I will try to inspect it and see if there's anything odd in the data.
4) Use the Linkmasta to make a backup of your Sonic cartridge. Then put that on the Flash Masta cart and play it.
5) Use the Flash Masta cartridge to write and play a different game (and/or another copy of the same game you had problems with).
The more I think about this, the more I believe that it's probably not a battery issue. It's probably some other glitch that just acts like a dead battery. If we can determine that it's a hardware problem with the cartridge, I can get you a replacement. However, I still think there's a chance that it's something else.
From what you've said, I don't see anything you did wrong. However, there's always a chance that something got corrupted in some step of the process. If there is a corrupt game in the NGPC, when you hit the corrupt spot in the game, it could cause the behavior you described.
Thanks for your patience!
