Hey guys,

Don't misunderstand the title, I'm not planning to code the best OS, nor any OS that has useful stuffs in it at all in fact

I just downloaded SirCmpwn's AsmOS and only tried to add this to boot.asm at line 140, following the readme's instructions :

Code: [Select]

bootedLoop:
	ld d,44
	ld e,28
	ld b,8
	ld iy,$90D3
	ld ix,sprite
	call PutSpriteOR
	ld iy,$90D3
	call BufferToLCD
	
	ld a,$FD
	out (1),a
	in a,(1)
	bit 6,a
	call z,ShutDown
	jp bootedLoop
sprite:
	.db %00111100
	.db %01000010
	.db %10100101
	.db %10000001
	.db %10100101
	.db %10011001
	.db %01000010
	.db %00111100

The shutdown code is working fine (I mean that it effectively shuts down when pressing [clear]) but the sprite ...

I didn't change anything else ... do you know why it's not working ?

Thanks by advance

I think SirCmpwn can help you on this, you can contact him on EFNet via PM.
