sav's you dumped from your original cartridges using an AR GBX back in the days when you were still young and life wasn't a friggin mess (or maybe you just want to continue that savegame you started on emulator earlier this week who knows):ġ) Start the GBA VC game if you haven't yet (I'll be using Golden Sun as an example) to make the Wii U create the data_xxx_xxxx.bin files in its internal save folder. I'm assuming you've just installed your favourite GBA VC game/inject on Wii U and now want to use one of those 10+ years old. Simply put, you'll want to grab the internal GBA VC savegame file, ( data_008_0000.bin) from your Wii U, feed it with data taken from your GBA. As long as you don't touch any system folders or delete files like very_important_file_dont_delete_or_brick.dll you should be fine but most important is that you feel somewhat confident with what you do.

All you need is FTPiiU everywhere on Wii U, a Hex editor on PC and a bit of knowledge on how to use these things I hope you're familiar with FTPiiU and manually fiddling around in your Wii U & its savegame folders ( /storage_mlc/usr/sav/00050000/10XXXXXX/user/8000000X/data_0XX_000X.bin) and that you're aware of the risks that come with doing so. What's nice is that – aside from a Wii U running CFW, obviously – you don't need many tools/programs for the way I'm gonna describe (especially a relief when you're on Mac like me). step 1) & 3) of it and reading it before or alongside this won't hurt.

This Thread (/threads/tutorial-bring-your-wiiu-gba-saves-to-3ds-gba-vc.464919/) was very helpful, esp. After spending some time puzzling I eventually found a way that worked with most of my GB/GBA games (Golden Sun 1&2, Metroid, Pokemon Ruby/Emerald and also Zelda Oracle of Ages/Seasons, to name a few) and thought sharing it wouldn't hurt. I was looking for a way to use emulator/cartridge-dumped GBA savegames on Wii U VC and ran into a whole lot of 3DS related and almost-what-I'm-looking-for guides with loose ends but to my surprise nothing that was specifically addressed to this scenario.
