just tried your setting. interesting, 720p is less blocky now, transparency is less grainy/noisy, and the grass is different. Also red_Auto does control dynamic resolution, its what I originally used to turn it off, it does nothing on XCDE though.
With 2.0.2 I used the "Next method", you will need the "exefs" and the "romf" from it. Take a folder like "Max 720p" and put it in the mod location "0100E95004038000". Inside that "Max 720p" rename "exefs_patches" to "exefs" and inside the "titles" folder look for the "romf" folder and move it...
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
