again thank you wermy for these guides ! can't say it enough ! and thanks as well for the mention :) as for the card reader replacement, got it here : http://www.ebay.fr/itm/371379245392 and got another one from here as well http://www.ebay.fr/itm/172275938725 do not mistake them for lcd replacemen...

I've bought almost all of the parts and am excited to get started. Does it seem like it would be a big problem to try and skip the game cartridge and fashion an SD card reader into the side of the device? Seems like you could fit a much bigger battery that way.
