I apologize in advance if the translation sounds unnatural, as I'm not very good at English. As a beginner, I managed to run runClient in my own MOD and display items in-game by watching videos posted on YouTube. However, the item images did not appear. Since there's no one in Japan who can help me, I humbly request your assistance. I thought checking the directories and image names within IDEA might solve it, but... I committed the src of my mod to Git. If anyone has time to take a look, I'd be very grateful. https://github.com/ZousanElephant/noob-mod
