Hi everyone! I was testing the best way for speedrunning this game with emulator. I discovered that Bizhawk is the best way in terms of accuracy between runners: Any pc is valid now (retroarch cores will be not valid, because the screen charges can be too fast depending of your pc). This will make the runs slower, but the accuracy is almost perfect. By the way, everyone runs will have to be updated for that change. I will post the rules for running asap. Thanks to malestrom and kingpomidor for your help! :D
