Noticed that an issue with Rayman 3 Hoodlum Havoc was reported on one of the gpsp compatability lists. Cross-checked against mgba and revealed the same issue reported as being present in an earlier version -

https://github.com/mgba-emu/mgba/issues/377

This PR applies the same fix as used in mgba. Could affect other games also.

Yeah it fixes a couple of odd games, but it's the correct behaviour, so let's merge it!
