Come on, first sorry if I'm posting in the wrong place, I don't know where my subject would fit. I think maybe I can find someone who understands about old computers, and assembly language, machine language in this forum.
I have one of those fake china video cards, scam, that says gtx1050ti, but it's actually a gts450. For those who have never heard of it, it is a functional board, but it has had its vbios modified to look like a gtx1050. Fixing it to look like a gts450 was easy, the problem is that it "pretends" to be a 4GB, when in fact it's only 1GB. Using a hex editor, I was able to tinker with random stuff, and I managed to make it "see" only 2GB. On the internet, there is a supposedly "fixed" file which faira it detects as only 1gb, but this "detection" is incorrect, and games will crash as soon as it exceeds 512mb of memory consumption. I've tried 1001 different bios, apparently there isn't a correct one. So I know the way is to modify the firmware to reach 1gb.
I could be wrong, but I believe that the vbios file is a binary, which can be read in hex... And that could also be converted to assembly. Someone with assembly skills/knowledge, could help me reach the goal
Why didn't I just throw it away and buy another one? Because everything got very expensive, and I live in a third world country, where my currency is worth 5x less than the dollar, and the average salary is extremely low, so buying a card is out of the question for me. Also, a gts450 would suit my needs well, i can play fallout new vegas with it or any game that doesn't exceed 1gb in vram usage, but i wanted to play fallout 4, and unfortunately the card will crash.
Is what I want possible? Or am I dreaming too high?
