Hello. I'm sorry for the delay in reviewing this PR. I'll try to do it as soon as possible.

Hey, I'm on business travel, and I'll be able to check this PR only on the upcoming weekend. I don't want to delay it for so long 😖

If you can test your changes on klo-gba.js, it would be great.

No problem, I will test the changes on klo-gba.js in these two days. Thanks for your help!

Hey, I finally tested this PR, and it isn't working. When I try to run npm run start or npm run build, it failed because of missing a babel configuration. And even after fixing it with the following patch:

I have the following error on the sample project:

Uncaught (in promise) TypeError: Cannot read properties of null (reading 'setCanvas')

Before trying to test on klo-gba.js, it's better o make sure that it's working on the sample project within this repository.
