On part VII of the LGFR walkthrough (http://www.psypokes.com/lgfr/walkthrough.php?part=7), in the rock tunnel, it says, "Head up the ladder after these two trainers. To the left of here is another trainer."
It should be right, not left.
Also, on the Route 8 and 7 part, with the trainer battle super nerd with only the koffing, it says the koffing is level 24, but it is really 26.
For proof, I was playing the game itself while using the guide.
Thats all for now. Thankyou for hearing me.
