I was going to try this after reading your post but now the old girl refuses to boot up. I will lightly be away from everything for a while (a week at most all going well) so if anyone else could do a comparison between the two versions that would be cool.

I know amipal did do a side by side with the original levels not that long ago but can't remember the specs of his machine.

could copy speed to chip ram be what influences performance on the TF1260? seem to remember that the CPLD code for ram access has not been optimized as of yet but could be wrong. Great card non the less

I might take a stab at the vertical melee bug later if I get a moment.

And there, non-coders, in a phrase, you have the wizardry that still pervades the Amiga scene. Thank goodness for you guys and other like you. :-)

What compiler does this compile with?

It's not compiled, it's assembled.

Well, it does say compilable in the first post... Tomayto, tomahto

It does. I suppose the point is, it's all assembler. Pipper posted some info way back in the thread on what you need to get started. I'm building in Linux, the instructions worked a treat.

OK, guess I'll look through the thread from the beginning then.

Found it!

Should probably add that to the readme.

We could also implement some CI/CD on GitHub to always have the latest version built automatically.

Ive probably mentioned before, but if not, I am running a TF1260 at 50Mhz, when I load the game FPS counter is showing maybe 9 FPS (can bob down to 8).

Is this expected performance on real hardware?

What keys can I use to increase/decrease screen size/border etc?

Cheers

Check out this video for comparisons between a December-assembled version versus the existing WHDLoad version on a BlizzardPPC with 50Mhz 68060.

Maybe the true frame rate is off due to vsync issues. It's easy to halve the frame rate when trying to sync a double buffered screen to the vertical blanking. Maybe triple buffering is needed. Just to really give us some annoying bugs to fix.

Wrong thread. I was replying to the 31fps RPi4 result in the other thread. Nevertheless this is probably a better place to talk about it.

Thanks, compiled/assembled fine.

@Karlos
did you make any progress with this? I guess the only check for vertical separation is weather the player and the enemy are on the same level (upper/lower)

I haven't had any time to look yet. My assessment is the same as yours though. Just a vertical proximity check. I think the issue only occurs when the attacker is in the same zone, but that may be just that melee attacks aren't triggered across zone boundaries. Which would be a different bug IMO.

Thanks for the great work! One Question, is there a RTG Version planned?

Planned is a strong word...

It's 100% on my hitlist. However, my main interest in RTG is to experiment with RGB output more than just working in 256 colours.

[Lizart]

That sounds interesting I'm curious if we can sketch out a few more fps with rtg.

[abu_the_monkey]

Adding RTG support shouldn't make it slower on zorro3, but on zorro2 setup where copy speeds would be slower than with AGA (I think) maybe not such good news (other than it might work on non AGA hardware).
It depends where the main bottleneck is I guess.

On the flipside, for PiStorm users...

It is a good point though. What is fast to VRAM performance of your typical Zorro 2 card? That's what we need to understand for that equation.

I was spoiled with the BVision, you could get around 15MB/s from the 040. Higher still on 060.

I guess it will be limited to the zorro2 bus speed, I seem to remember speeds of around 3.5mb/s being mentioned.
