Why can't the emulator find and set the right region for each texture automatically? I just forgot about this option, but I think Duckstation works this way too (although Duckstation is not a good example for texture replacements, since it has many other issues which makes this feature unusable).
I also asked for
an option for wildcard characters. It would fix like 95% of the broken textures in DQ8. However if at all they only would do this for the base hash, while DQ8 needs it for the CLUT hash. I wonder what it is like in other games? Which part of the hash is equal, the first or the second?
Yeah well, sorry to say, but this sounds like a stupid excuse. As I heard they once also kept saying that texture replacements in pcsx2 are not possible at all until Topaz showed the opposite. To me that sounds more like a lack of will to work on these issues. I also made another suggestion like creating an ini file, inspired by ppsspp. But they don't want this either. I wish they were a bit more constructive about finding solutions to workaround this issue. But to me it feels like that they give zero fucks about how good or bad this feature works, because they self don't use it anyway.
A good example what can be possible if a dev is passionate about game modding is Dolphin. Not just that texture replacements work much better there (they allow wildcard characters too), after dynamic input textures they now also work at custom materials and mesh replacements. It's really crazy what is possible if devs want it too.
