I recently got my hands on thousands of sprites via a chinese website (the game originally is called Legend of mir). I purchased the client and exported all the BMP's to PNG's, allowing me to use nicely in construct 2.
The only problem , im a graphic person , not a coder...although i have started on this game.
If anyone is interested then they can drop me a PM and i'l give you extra contact details and explain exactly what im trying to achieve.
heres an example of how far i've got.View Here
