Correct spelling, explanation: this word is a merge of the prefix over- and the verb ride. Overrode is a past simple form of the verb override. Therefore, the right version must be spelled with a double -r. It’s very important to always look at the construction of a word-formation basis. Therefore, overode is an incorrect spelling and the correct one is overrode.

Definition of overrode:
verb (past simple), to prevail or have dominance over
The presence of my friends overrode any negative thoughts.

Collocations with overrode:
Some most commonly used collocations include: override a transaction and override a veto.

Incorrect spelling, explanation: since the word overrode consists of two parts – over- and rode – we mustn’t omit any element of each of them. That’s why overode is just a misspelling: it lacks one -r consonant. This error can be encountered very often, mainly due to pronunciation and inattention. Always remember that the only correct version is overrode – with a double -r letter.
