As of now, you can submit runs to the lederboards played on PCSX2 (Nightly) v1.7. or higher. The emulation accuracy has improved dramatically in recent times and combined with the loadless timing and the load remover, PCSX2 can finally go on the boards as well. Some basic settings are specified here: https://www.speedrun.com/crashtwoc/forums/x5dlm

Please make note of these settings and remember that this rule change only applies to this game for now. Other Crash games will be tested individually and the rules for those will be updated if need be.
