The ' Save Chip Manufacturer ' is actually about ‘ LCD Ghosting ’ which named as ' Ghosting Adjustment ' in Ultimate GBA VC inject for 3DS and in New Super Ultimate Injector for 3DS.
To restore a save, you need to basically do step 1-3 again, then navigate to SD (card) on step 4, find your save file, and put it in the clipboard with Y. Then go back to agbsave.bin, this time choose Inject GBA VC Save, then restart and launch the GBA VC title to complete the inject.
I've had an EZ Flash Omega (Non DE) for about a year or so now, but I have recently found myself unable to specifically load GBA games. I am no wizard when it comes to this sort of technology, and I mainly got this flash cart so as to avoid paying exorbitant amounts of money to play games on [mostly] original hardware.
-If you don't mind having multiple GBA emulators use gpSP for GBA and mGBA for Gameboy and Color. -Best situation, having all three emulators (mGBA, VBA-NEXT, gpSP) installed and switching between them depending on the game.
What's the best way to play GBA roms and rom hacks on PS Vita?
I've attached an image of the folders (hopefully it's useful!). I'd expect to see the files in the roms folder tbh but they aren't there - the .nds files are but no gba files. They must be somewhere because I can load the save data on the game but I can't find them in any of the folders. They're potentially in the Nintendo 3DS folder but all the file names are just random alphanumerical codes ...
