Grab Easy CD Pro 95 from this webpage in the miscellaneous section. Install it on your computer and then open the program select "Burn Image from Mixed Mode" in the options, then Drag all of the mp3's in order of tracks in the audio window, go to the data file section for the ISO and browse to the file for the path. After all of that go to the burn options tab-(On the far left at the top of the window and set to 2x burn.) Make sure that you unselect the test write feature unless you want it to test before actual burn. After all of that proceed to click "Write" or "Copy" -(I can't remember the actual button that means the same thing.) Let it go and it will ask you if you want to burn the audio; click "OK" and the program will commence writing to the disc the ISO and MP3s in mixed mode. It should work!
Edit to last reply: You will need to convert the Mp3s to WAV before using Easy CD PRO! Sorry, forgot about that. Use a program like Winamp to convert the mp3s to WAVs. check on www.google.com search engine or in the miscellaneous section on this site for assistance as well. SORRy About that.
For your last question; grab SCDConv to see what country it is, once again, in the misc. section. Everything you need to know about burning and changing country codes before writing back to disc is in that section; it is your friend.
Cool, you are welcome. Yea Snatcher is awesome! I wish they would have brought Policenauts over to America too; I have the Japanese copy for the psx and I still have not figured out what to do on the game. Oh well. later.
