If it's the power supply, how come some games behave differently depending on the console and not the supply? I have the plain 2011 MVS converter and not the MagicKey, so shouldn't I have less current draw? I have a Unibios v3.0 installed on one of the consoles and it almost always reports an illegal instruction or address error at the points where the system would just reboot on the unmodded system. This console, BTW, is the one that tends to have "better" support for the games (e.g. games tend to crash later, KoF 94 and Ninja Masters work w/ minor issues). As this system has an internal board to convert RGB to S-video and component output, I'd think it would draw more current than the unmodded system.
