I finally did this last week. I had been meaning to for a while now. I got homebrew stuff setup, did a NAND backup and looked at what type of chipset my system has. I lucked out with a Samsung chipset.
Now I’m working with the fun stuff: homebrew apps, Pretendo, etc
The A3D (or A64) has an option to “overclock” the chipset so games that used to crawl on OG hardware run buttery smooth
