What I meen is that it would be a choice, romania or hungary. I would choose Romania just becouse I like them.
Apparently one company did - on Polish side
There were several volunteers from Hungary too, but the said unit crossed the border to help a Polish unit to reach Hungary and safety.
Only a small margin of Hungarian nazis resented Poles - for example when the Maczek's armoured 'Black Brigade' crossed the border after the order to evacuate was given by Smigly-Rydz it was welcomed as heroes.
Germans did ask Hungary to at least allow transit of troops and munitions - useful in the later part of the war, but that was declined by its government responding 'we would have a revolution here'.
During the war both, in theory enemies barely exchengade fire - Home Army even established half concealed section in Hungary (code name 'Liszt') and when Hungarian forces were in Poland they either 'ignored' POlish guerillas or supplied them with weaponry.
Hungarian troops deployed close to Warsaw in summer 1944 proposed to join the Uprising as 'Royal Legion of St.Stephen' which was accepted by the Poles, but had to be confirmed by the Allies (otherise the Magyars would lose combatant rights and would be shot either by Germans or the Soviets) - which didn't happen - German HQ learnt about it and decided they cannot risk putting Huns and Poles together. The units were redeployed to the south - there were some incidents between Germans and Hungarians so it might be the last call to order the redeployement.
Simply if someone wouldn't fight each other in this part of Europe it would be Poles and Hungarians - check Wiki for
Pole, Hungarian - two brothers .
PS IN a millenium of relationship there were perhaps two wars between Poland and Hungary - both etremely unpopular on both sides, the second (1657-60) a total disaster for Transylvania (everyone opposed the attack in that state - except the Duke - his advisors, leaders of all religious communities, even his wife) considered one of the greatest political blunders in entire history of the EE.
