This was something I had looked at with @Hammy ages ago, but it turned out to be a pretty large undertaking.
However, now with the assistance of Claude I started fresh and revisited the idea. The result is a patcher that will let you revive a cartridge with a dead IGS027A:

I hope it is helpful for the community. I also have a Martial Masters cartridge with suspected dead IGS027A which I am going to look at reviving next.
