Hi

I just want to show you the nice progress made by the team on the integration of the AGA chipset into the Apollo core. There is still a lot of work to do, but I'm pleased to show you 8 games, included an AGA one, running right now on the Vampire. On the video, you can see that we only use the DIGITAL-VIDEO cable to carry the chipset picture and sound to the monitor, therefore we are all digital ! The display is done in true 50Hz, so there is no tearing and no frame droping while displaying. It's as smooth as the original PAL displayed version. No configuration, don't need to tune up the prefs : it's just work out of the box. But we don't stop there : we have a nice complex scanline effect that simulate the rendering of the old beloved CRT monitor. So, best of both world : smoth without tearing, scanlined, but displayed without flickering on a modern display via the Digital plug.
Enjoy !

So does this mean near public beta?

There are no public betas, never have been. Only releases. Of course, since the feature set is changing all the time, you could argue that all releases have been betas...

Nice!
 
  Couple questions..
 
  1. can you turn off the fake scan lines (I am not a fan of them), give me migraines
 
  2. have you tested this with NTSC display modes/60hz frequencies?, I noticed your defender of the crown looks a bit squashed (probably due to PAL display settings)..
 
  Thanks!

" 1. can you turn off the fake scan lines (I am not a fan of them), give me migraines"
This is not yet implemented at this stage of developpement.

" 2. have you tested this with NTSC display modes/60hz frequencies?, I noticed your defender of the crown looks a bit squashed (probably due to PAL display settings).."
at the moment we work on the PAL modes in our intern build.

Thanks.. #2 explains the odd aspect ratio (DOTC was originally an NTSC game).

Will PAL/NTSC mode be switchable someway in real time?
I remember A1200 let you do this by pressing spacebar at the boot menu screen, I wonder if Vampire will let you do this at any time.

Thanx

GOLD3 does not contain Turtle Mode for the stock a1200 speed. Here are a couple of WHDLoad games that will benefit of it. Audio and video comes through DIGITAL-VIDEO.

So experimental gold build 2.5 is not beta, so why is there
Bugs then if full release?

Hi

here is the second video with 8 other games, the early startup menu and a closer look at the scanline effect:

I will try to source a better camera for the next video, but anyways i tried to give you a closer look at the scanline effect at the end.

If gold3 does not contain Turtle Mode, what can be done for games/apps that currently are not in WDHLOAD?

Bugs in one of our releases? Impossible... :)

The problems caused by too fast CPUs are usually caused by the CPU finishing too early and the blitter still being busy but the CPU not checking and waiting for it. Gold3 has total control over the blitter as it becomes part of the same chip as the CPU. Thus, it is possible to not allow the CPU to start the next blitjob before the preceding one is done. This also means that there is hardly any need for slowing down the CPU and hence no need for the turtle mode.

Do all games have to be configured to run through hdmi or once this feature is in place all will automatically display there?
