3d Sonic Ports

[Gabrielx36]

I have a New 2ds XL. On it I have 3D Sonic The Hedgehog 2 ( an emulated port of sonic 2 on the 3ds, they even say emulatetion on one of the menu screens) that I purchased awhile ago from the eshop for $5.99. Then just recently I modded my 3ds and tried to see if I could extract the rom from the port. So I went into Godmode9 and built a cia out of it. Then I went to my computer and used the PackEnglishV9 tools and extracted the cia. Then I look in the ExtractedRomFS file and then the system folder, then the roms folder and it showed me two files. Sonic2.SGD.m and Sonic2_USA.SGD.m. I tried putting them in fixchecksum and the Sega Genesis Checksum utility master. But fix checksum never made them better and Sega Genesis checksum refused to run. And yes, I did try changing the file extension. Any ideas to get the roms working?
