040 would be great for 060 games/demos. While I'm fortunate enough to have a TF1260 with a rev6 cpu, those are about as easy to find as unobtainium.

Interesting to see that the new Rev1.8 Miniming card from 2022 proposes also a kind of hybrid with the Pistorm (running official core and Emu68) I really like their statement : "PiStorm compatibility – Using optimized Emu68 over 800MIPS of CPU performance! About 3-4X speed of Vampire. " https://www.minimig.ca/index.php/product/minimig-v1...

In addition to Sorge of course.

Afaik a good chunk of the Amiga core needs a rewrite (starting with Paula). It's still the old Minimig from 2005ish underneath it (improved obviously)

Core? It’s software emulation, not FPGA with soft cores. musashi runs as a process under Linux and there’s other software on the Linux side that offers services like virtual scsi, networking and framebuffer for RTG. Emu68 is a different beast, it is a bare metal emulator, so no Linux and everything Linux offers. Instead everything must be done fro...

And wave good bye to virtual scsi, RTG, networking etc?

No? They're just switching the 68k core.

PiStorm is switching to Emu68k though

I’ll post code/binaries tomorrow! Probably this is enough performance for v1 now, I should focus on the main problems: i) Crashes often on clicking icons! ii) Crashes when I put in 68040.library Any 68k gurus here? Never click on icons, problem solved! Did you try with the 68060 library? afaik the 060 is just a refined, lower voltage version of th...

Prety much this. You're just spamming the thread with something that's still experimental.

This has been discussed here and you can find his posts on the subject. Please point to them, I find only 6 posts here by Mike and 106 over at atari-forum, but nothing that really covers what you write... I just see his tg68 spin-off that he calls m68k which he has put on github already, which is more like a 020... nothing about 040/060. I see kol...

What did happen to Gunnar’s offer of 060 level performance to any project with the option to unlock the 080 performance at a price? I only saw reference to it on a1k.org a while ago Other than that, there are no better 68k cores than the one we have. Mikej from FPGA Arcade Replay is developping a 68040 core and porting it to the DE-10 NAno https:/...

The V4SA is not the answer. It's in far too limited numbers and costs an arm and a leg (about 600eu) I don't think there's even more than 500-600 units out there (and I'm being generous with that number) I think there are more Vampire units out there than we suspect. When they visited the Amiga32 event, they had 200 units (stand alone) with them. ...

Tbh having a 68040/60 option would be great as a dev environment for me. Having a super small sized ASM dev setup to dabble into Amiga coding without having to break the bank on a warp card (and equally capable 68060) would do wonders to the current Amiga demoscene. And no, a WinUAE dev setup really isn't optimal for that. It's fine for the basics ...

Isn't Mike working on a 040 core that he will make publicly available? That should alleviate the need for a 68882 core Haven’t really heard about this, but it depends what kind of 040 core it potentially is replicating, whether it includes FPU at all. 68EC040 had neither FPU nor MMU, 68LC040 had MMU, but no FPU. He said both would be there (FPU an...

kolla wrote: ↑Sun Feb 07, 2021 2:27 pm It requires quite a few things that don't exist currently:
* full 68030 (not EC) softcore instead of the current 68020 tg68
* 56001 DSP softcore
and possibly also 68882 softcore (with 80bit precision)

The torrent is available on the Commodore Amiga facebook group in the files section

Don't forget you can use VHDTool to convert the img file to a VHD instantly then mount it. This saves the whole step of burning to an SDCard and pulling files back. I have a clean 4GB partition with a clean working setup that is fast on Mister (Havana release) with RTG and Miami setup, I removed the Roadshow demo. I have made a 29MB partition for ...

Some other games also benefit a lot from it due to the back calculations they do, Cicilization, Colonization, Sim City 2000 and games of that kind are prime examples of that While this is technically true, none of these games do so much calculation that speed improvements beyond what MiSTer’s accelerated 68020 CPU already does today will really be...

No, not unless additional work has been done on the game (outside of those 3D games you mentioned, which do benefit). 2D Amiga games generally run at the same frame rate no matter what the CPU speed is. That depends. If the game's logic is tied to the CPU speed itself, then having a better/fasyer CPU can break the game's code. Alcatraz is a good e...

When we're talking 68k, are we including 68040 and 68060 (so with MMU/FPU) or just offloading 68000/68020 to the ARM CPU? Well, I am aiming for the whole shebang - 68040 / 060 + MMU & FPU 😉 CPU on the ARM with custom chips and RTG on the FPGA seems like the best approach for a very faithful Amiga recreation. Sounds super promising and would pr...

In the meantime, Mahen mentioned that someone else is planning to implement RTG, but didn't say who. Hey robinsonb5, yes, I planned to work on the RTG, but at the time I didn't know you were already working on it. There's really no point both of us doing it, plus I would really love to try the 68k CPU emulation on ARM. I already have the DE10 nano...

Like RTG via HDMI and 256p via RGB out?

Actually, the vast majority of North American sales were indeed gaming-related - Toaster use was widely bandied about but resulted in actual sales of less than 20,000 units (source: NewTek). It's worth remembering that the machine was designed initially as a games console - the expansion capability 'snuck in' by its designers. While I appreciate H...

At some point, particularly with FPGA, you have to draw a line somewhere in the sand. I mean, what is an 'Amiga' anyway? In the Commodore days, it was easier to define No it wasn't. The Amiga was a productivity computer with a big focus on video editing and real time video overlays and sold as such in north america It also was a gaming machine wit...

People not wanting more options that they can opt out of really baffles/puzzzles me

Next we'll hear that we don't need a 68030 or 68040 core because games don't need it anyway and who does productivity work on it in 2020?

In my opinion, once you want RTG you can just as well drop FPGA and go straight to whatever UAE of choice - the *ENTIRE* point of FPGA Amiga is to replicate the Amiga chipset, and use it for what it was good at. That's a rather narrow view. The Amiga has had graphics cards as early as the first Amiga 2000 release. It was a productivity computer as...

@Mikej

I've been waiting on your Replay 2 project since I missed on the initial one Hope it's really just a few months away Even if you make a DE-10-Nano build (and I would get a new Nano specifically for it and have a different one for everything else)
