I am really confused by this. The disk could be a faulty disk, which actually has to be cleared with my publisher, and they will replace it. On the other hand I am not sure if the game ever has been tested on that particular OC-118N clone. The original Oceanic is very compatible, almost 100 percent they say. You don't have the option to try with a 1541 or 1541-II?
Regarding the disk image that's the most confusing part. The game has been loaded thousands of times on C64 machines from an SD2IEC without any issues at all. I load it from an SD2IEC myself, at least on the Plus/4. Did you download the disk image from here? Or are you using the one that came on the SD card supplied with the game? Still this must have something to do with your hardware. I don't have any other explanation as the game runs perfectly on pretty much any C64. Is the SD2IEC from "The Future was 8-bit" or is it a different manufacturer?
One more thing to add... did you load that particular disk image in an emulator to verify it works?
