This is a fan translation of the Japanese NES game, Kunio-kun no Nekketsu Soccer League. The 'En by PentarouZero v1.2' translation makes the game playable for English-speaking audiences. The original game, developed and released in Japan, now has an English version through the fan translation.  The core gameplay remains unchanged, offering the same soccer-based action, but with English text.  The quality of the translation affects the overall player experience. The original Japanese developer and publisher would require additional research into Japanese gaming databases.
