Thank you guys. Cartmanuk, tried R4-Pro and R4iProUpgrade provided by you above, also tried R4Pro file from the link provided by Plainscript. No luck :(
Cartmanuk, the first link doesn't work.
CalebW, thanks. The issue is I have no idea on what's the official name of this card. I already tried couple of dozens of firmwares, tried everything with word "pro" in the name on gbatemp.net and now also tried everything with word "pro" on filetrip.net. No luck so far :(.
Hello,
I have this card. The site www.r2ids-pro.com indicated on the card isn't available (for at least half a year already based on web.archive.org site). I hope there's another source I can download required firmware from or there's someone who has similar card and can share firmware with...
