Hi, I'm posting here because I can't fix this problem I'm having on my own anymore, after several days of trying, reformatting and troubleshooting... I end up like this.
I have an R7 250X with ATOM-15 BIOS installed in it, I use RetroArch with CRT SwitchRes, and I tried Windows 8.1 and Windows 10 with both the Crimson and Adrenalin drivers. Nothing worked well.
I'm pretty sure this card (rebranded HD 7770) is perfectly compatible with this because when the driver won't crap out, it works fine, but then it ends up crapping out and I don't know what to do. Here's my problem:
I want to use an N64 emulator in RetroArch, which for some reason won't display full screen unless I set the desktop resolution to a super resolution of 2560x240. OK, so I do that, and for the most part it appears to work... Until I shut down the computer. Then I bring it up again and the video output is garbled. I can't see anything, and It's hard to even uninstall the driver in this state. When this happens, the only fix I found is to regenerate the video modes using vmmaker (I used a tutorial from cdcruze that explains how to set up the super resolutions ini file so it works with retroarch) but right now , I can't even do that! even after uninstalling the driver then installing it again, now vmmaker says that the video modes "are rejected by driver"
what's wrong with this?
How do I fix this mess?
Sorry for my tone but I've been several days into this and I'm sick of uninstalling and reinstalling this broken driver over and over and even trying several Windows versions in case, idk, win8.1 wasn't fully compatible. But same broken, garbled display after working fine for a while.
Hope someone can help me.
