SameBoy is not just another Game Boy emulator, it’s currently the most reliable and accurate. For example, it was the first emulator to correctly emulate Pinball Deluxe, one of the holy grail bugs of Game Boy emulation.
I wonder how it compares to Gambatte regardig accuracy.
Gambatte development kind of ground to a halt in 2014, which is one of the reasons SameBoy started development. It seems gambatte had a burst of development activity last year, but SameBoy is still more active. That discovery about Pinball Deluxe happened in 2017, and I can’t immediately see any obvious reference to it in Gambatte’s commit history.
