http://forum.romulation.net/index.php?PHPSESSID=8d6ih7al8ad2ucqcsbs8qip323&topic=58440.msg1371008#msg1371008 The person there has the same exact issue that I currently have with Dragon Warrior 7. Same firmware(6.60 PRO-B10) and same program(ImpalerPSX) used to make the eboot as the one used in the guide sticked above makes the PSP give me an 80000004 error code whenever I started it. I have heard of a possible plug-in fix but I'm not sure which one actually makes the game work since some people report that the newer ones don't work with some titles. Just so you know I have 0 plug-ins installed. The "menu" screen after the title screen: Any solutions?
