We've run into a potential use case for the Sameboy core getting updated to .11 in Bizhawk. I've run through some test TASes of Mickey's Dangerous Chase on both GBHawk and Gambatte, and neither in Bizhawk 2.3 properly emulate the game's sprite lag. As soon as the first enemy shows up, the emulators lag more than on the real console. Sameboy may already be accurate enough for this game, and it would be interesting to see if TASing Sameboy .11 could allow for a proper console verification. We believe that there already at some point was a Sameboy .8 core in Bizhawk, and the API has not changed much between the releases, so it may not be a complex update. I may be able to assist with updating the emulator myself at some point but right now I'm tied up with Pokemon Yellow NSC TASing.

I've documented this set of test ROM results for the current Gambatte core and GBHawk core, Sameboy passes all of these tests. It looks like upgrading the sameboy core could be of significant benefit. https://docs.google.com/spreadsheets/d/1T4BH72RQf8DT1YrpK1y4zizJn33rBf7BUZi2mVOKMnU/edit?usp=sharing
