rmac GPU symbols not exported

Wed Jan 9, 2019 9:30 AM

I've this code, why _gpu_code_start it's exported but_gpu_sprite it's not exported?

 

How can I export a label that will be located at GPU RAM?


_gpu_code_start::
	.gpu
	.org G_RAM


	movei #gpu_sprite,r0
	...


	.long

_gpu_sprite::	dc.l 0

First version, 100% C code, no GPU, no Blitter, 8 bits bitmap for rendering, screen drawn and cleared pixel by pixel (using byte pointers).

 

By the way, this demo it's a fact why you shouldn't use the emulator to optimise the code (sorry if there are newer versions or better emulators). Look at the times...


Vertical lines on solid colours

Sat Nov 17, 2018 9:53 AM

Why my Jaguar shows some colours with vertical lines, instead of a solid colour? It's like even or odd pixels don't get the same RGB.

 

Can be fixed?

 

Thanks.


Object processor bug?

It looks that the CLUT #0 it's always black, If you change the first color palette to any colour and draw a 8bit sprite non transparent (haven't tried with 1, 2, 4 bits), the pixels with color index 0 are drawn in black, always.

 

Anyone have the same issues?, I've been looking at the code and looks right, but I can't use the color #0.
