Are you sure that you tried using HDLoader? HDLoader doesn't have coloured debugging screens.
When a game totally can't be loaded when it's not known to have compatibility issues, it probably means that the game can't be accessed properly... which usually hints a bad installlation, bad disk (HDD has bad sectors and the game got corrupted), or bad game rip. Using clone/compatible network adaptors can also cause game loading issues.
How are you installing your games? EDIT: Just remembered that you wrote that you used WinHIIP. I hope that you were using the latest version of it (v1.7.6, if I remember correctly).
Which version of OPL did you use? If it's not something recent (e.g. minimum at OPL v0.8), you should really get a newer copy.
