I have some good news about Vitor Vilela's SA-1 Contra III being compatible with Canoe. Currently it works just fine until the game makes its SRAM file, which is an added feature. Once this SRAM file has been made, the game will always just go to a black screen upon trying to load. I talked to Victor about this and he said
"hey @teahouser, you're welcome, thank you! I think changing the byte x7FD6 to 34 (hex) might fix it, since it will make the chip no longer save the BW-RAM"
I have no experience modifying bytes, but if one of you guys would like to apply the SA-1 Contra patch to the game, hex edit the bytes listed, then create a patch of the now disabled saving, we should now have a functioning patch to add to the compatibility list so everyone with a SNES Classic can enjoy Contra III with zero slowdown. (it's glorious)
