Now we just need a car and some curves

It's been a few days, but curves and hills have been added to the road engine.

Eager to watch a new video!

Here you go

You see lateral movement in the video, it's because I'm moving left/right with the cursor keys while recording it. The next steps will be to :

change the geometry of the current road, in order to have a result closer to the road on Outrun
add a car sprite
fix known bugs

Would a g9k give any observable boost in framerate, or is this mostly the Z80 at work?

If you use long OTIRs (with bigger values in B register), you might try to optimize speed with kind of loop unrolling technique

i tried to modify it to the case when you don't know exact number of bytes you OUT.

Your method seems quite complex... How about something like:


OTIR_UNROLL:
	LD E,A
	AND 15
	LD B,A
	OTIR
	XOR E
	RET Z
	LD B,A

OTIR_LOOP:
REPEAT 16   ; 16 OUTI command in a row
	OUTI
ENDR
	JP NZ,OTIR_LOOP
	RET
