zsnexbox on xbox is still at an ealier core BUT snes9xbox was updated to include core 1.51 and 1.53. there are 3 cores in snes9xbox to choose from in the menu for better compatibility,so you should maybe try that. link for newest version of snes9xbox. Code: https://firedrop.com/bcf23ddd42a18e56
Thanks very much for this! The cores don't seem to be as well-implemented and optimized for speed as ZSNEX is..I'll likely stick with that. Thanks again for making me aware of this, though!
