Actually there isn't any skip level cheat in the PC version of Oddysee, only in the PSX one! You could try the -ddcheat for pass that area (if you want other help, send me a PM)
EDIT: savegame would be fine, just tell me how many Mudokon you saved (if you remember), or I just play saving all of them until I finish both temples, I can complete the game very fast
