And saving works too, so the battery is still good.
Also, info for anybody wanting to make their own repro, there's a lot of misinformation out there about the differences between the SuperFX-1 and SuperFX-2 chips. Star Fox 2 does NOT need the SuperFX-2, it runs fine on the SuperFX-1, as the only real difference between the two is that the SuperFX-2 can map 16Mbit ROM, and the SuperFX-1 can only map 8Mbit (however, the MARIO-CHIP version used in Star Fox has a couple other issues so it doesn't work for Star Fox 2, you need a GSU-1 chip).
Anyway, if anybody's wondering, here's a list of all of the SuperFX games and their suitability as a Star Fox 2 donor (SNES Central doesn't have any info on Winter Gold, so I'm not sure on that one)
Code: Select all
