textures dumped with several small blue boxes and upside down

[xxh3llraiserxx]

Some time ago I started a retexture project of San Francisco RUSH. At that time I've dumped all the textures (I guess) of the game and started the project... but I've noticed a "strange" thing related to the dumped textures, they all are upside down and with several small blue boxes... so this is normal or I have done something wrong? At that time I've used Project64 1.6 with Glide Napalm to dump the textures... I also tried with other emulators/plugins but got the same result.

PS: Manage attachments is not working? I can't upload any image, it gives fatal error.

Not sure about the blue boxes, but I believe most games rip the textures upside down if not all. i just select the whole folder and rotate them clockwise twice.
