DISCLAIMER: These notes are from the defunct k8 project which precedes SquirrelJME. The notes for SquirrelJME start on 2016/02/26! The k8 project was effectively a Java SE 8 operating system and as such all of the notes are in the context of that scope. That project is no longer my goal as SquirrelJME is the spiritual successor to it.


Appears the SPIR-V 1.0 specification was released not too long ago. When I do eventually get to 3D graphics, it is just going to be SPIR-V and Vulkan at the core with an initial software renderer. Everything else such as OpenGL or Java3D can be based on that core so that there is a common OpenGL code set which does not have to be rewritten every single time for new hardware.


Having the stuff merged as this is now will most likely reduce the work needed in the future to add read support for KBFs since most of it will be done at least in the raw format.


I had this idea of using a 64-bit pre-link table but that is not really needed as the KBF is essentially a 32-bit format. The values are only valid the KBF is loaded at a base of zero and the pre-link table is loaded at a very large address. Making it 32-bit would simplify things a bit. However for the case of pre-link referenced datas that would be complicated. I suppose as a solution to that, those values will instead be referenced by cells which is a multiple of the pointer index as required. This way the pre-link references while in the KBF are 32-bit can be loaded into 64-bit form without requiring magical stuff to happen.
