Valuations please (Nintendo stuff)

[Binary Defence Crimson]

I might bung some of the remains my Nintendo collection in the sales forum, or on eBay if no-one here wants 'em. They are all great condition and complete, like they have just been bought from a shop, unless stated otherwise. I'd just looking for rough estimations for how much these a worth, really. It's not an exact science, just a ballpark figure.
Thanks.

F-Zero Maximum Velocity - GBA
F-Zero X - PAL N64
Gradius Advance - GBA
Kirby's Fun Pak - PAL Super Nes
Parodius - PAL Super NES
Super Gameboy - PAL - box good condition, manual OK condition.
Super Metroid - PAL Super NES - big box in good condition, manual/guide reasonable readable condition.
Terranigma - PAL Super NES
The New Tetris - PAL N64
Yoshi's Island - PAL Super NES
Zelda: Link to the Past (with map) - PAL Super NES

I'd say everything boxed would be worth at least ?130? Maybe not that is my estimate.

Try a completed items advanced search on ebay to see how much things go for.
