@mikej

I was just curious if you maybe considered using Apollo core (Vampire
cards of course modified) instead of real 060 daughterboard as an option
as it would make two great project finally make one.

(BTW I didn't say Natami :hammer:).

Great work anyway !

He already answered it... he will use his own core

I thought that was for mainboard ?

If mistaken then sorry for double question.

No also for 68k core

Cache is up and running, few more tweaks but looking very promising.

Unfortunately the Apollo core is closed source, and my aim is to get all this released completely as soon as possible. Work is continuing on my own superscaler core, we'll see how that goes....

Definite speed boost, and I think another one is coming shortly!

RTG speed is now great, although there is still very limited blitter usage.  If I can ever get some time to finish my commenting of the PicassoIV driver, I should be able to implement quite a few of the system patches to use Replay's blitter-engine.

Speed in benchmarks varies greatly - between 55% and 113% the speed of an A4000.  I have a feeling that is going to just about double shortly.  :)

I added myself to the pre-order list. Got tired of trying to find an A4000 (my dream Amiga) for a decent price.

Using the new cache core shows that Replay's Amiga core is now faster than MIST's!   More speedups to come too!

Several CPU fixes have been done, and now I can actually run my PC emulator (PCx).  Since there is no FPU in the 68020 core, you have to use PCsx (the FPU simulated version).  It works pretty well!

Hey Guys,

I think it's my first post here but hey it's never too late :)

With the help of Mike I've been able to use a physical drive on the Replay. In addition to the core changes it requires a small pcb to interface the drive and the board (thanks to Jim for the advice on the design!). I've made 2 pcb, one supporting an Amiga drive and one supporting a standard pc drive.

I've uploaded a short video where I boot a few games (+ showing some RTG in 1280x1024) here:

https://youtu.be/mByHYxP5yDw

Back in January I made a video for Mike to show the core progress, thought that could be interesting as well. Note that since then the Replay is supporting more RTG resolutions :)

There's still some problem to fix with the floppy drive but getting there :)

Cheers
