Fingers crossed to the this great project!
If you need help, let me know in PM / DM / Twitter.
I can help with graphics, VMU, movies, sounds, simple hacking and of course in selfboot image creation and tests on a real console.
I have already created several translations for the SEGA Dreamcast console (Polish language). I am currently working and helping with Napple Tale and my own translation of Karous (english).
