I've also had problems uploading large files >10mb via the downloads area. I think there's a problem with the code in the downloads module.
Can you put it somewhere online where I can retrieve it? Also, I would assume maslovsky has access to this file, being that it's pdaXrom related (I could be wrong). He has direct access to the server, so he could always put it on the server for all to access.
anonuk posted it on his server http://www.webspinners.co.il/pdaxrom/pd
... -SD.tar.gz maslovsky doesn't have this. It's a tweaked version of the file system for placing on a SD. The details are in the pdaXrom section of the forums in the Dual Boot thread...
