So I did do that (Back button during a game -> Advanced options) and it says ARM-v7 lib and version is 101. I know I set it to SVN but it has issues even on v74.
My device is a Galaxy A13, CPU is 64-bit, but its OS is 32-bit. If yours doesn’t have vertical lines and I do it might be because of my phone, but again IDK. You could try to provide another patch for v74 only (as updating SVN may be problematic) for 32-bit phones like the A13, because the previous patch for versions greater than v99 may have not worked on my side. Here’s my device’s info BTW.
btw my device is a Galaxy A13, it’s a budget phone by any means but hey if it can run DOS game then it certainly can.
What are you talking about to be exact? Just asking for what are you referring to.
