Introduction

• This is an attempt to get Minecraft Java run on a jailbroken iOS.
• There's no eta on this project.

How can it work?

• Use OpenJDK 16 from Procursus to get real Java environment.
• Use GL4ES for OpenGL -> OpenGL ES translator.
• Use our LWJGL3 iOS port.
• Use same launch method as PojavLauncher Android.

Current status

• Java Runtime Environment: OpenJDK 16.
• LWJGL3 iOS port: works
• OpenGL: GL4ES
• Did Minecraft recognize OpenGL?
• Does it work?
• Current error: GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT tested on Minecraft 1.13, 1.14 and 1.15.2 (probably all other versions).
