liquidpolicenaut, I'm not sure in what to help with the DreamCast but I can point out you can paxplode it in a PC and you can find errors and you can probably change it, I guess.
As soon as I beat "6c", it fades out as normal, the "loading" screen comes up and then, instead of loading the next part of the level, it fades away into the credits! I have tried to reburn the PAK file with different versions of the 1st-read.bin file but they all yield the same results. Any ideas/info as to whats going on and if I can fix it in any way?
That's what I had before. You can try to find errors, but before you do that, you need to check with the OpenBOR log txt and find out what error caused the problem. Once you find the error, correct it. I forgot how I corrected it, but I did, however, makepack it into a clear one. I suggest you do it before you put it to CD if you're a DreamCast person. I'm not a DreamCast person though. That's all I can help.
