Wanna thank @Gericom for this wonderfull work, latest Cache-hicode branch tested and even Emerald R.O.W.E is working like real cart(EZ Omega). Gbarunner 2 crash every time you try to use the bag but not on Runner 3 Hicode. However theres a bug...
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
