looks like you are right. Does anyone have any info on availability, etc ?

"Latest version of ScummVM ECS running on my AGA 030 (as I don't have a real ECS machine). This is a 256 color PC VGA game which is converted to 64 color ECS Amiga mode in real time."

Yes, this one:

http://aminet.net/package/game/misc/ScummVM_ECS_030

It says fast 030 in requirements, but I don't think it actually uses any specific 020/030 instructions, Novacoder should know, he built it.

I wasn't aware it existed, great work NovaCoder!

[kipper2k]

awesome, thanks. I seen the vid was done by "Novathecoder" thought it was the same person, not quite sure

Yep that's the one I meant, it says 030 but should work fine on an 020 AFAIK

Most demanding software that you can run on an Amiga OCS/ECS ever LoL

That's one of my older videos with a different user name

030 code is 100% compatible with 020 code in terms of opcodes (they are identical except the 020 has one extra instruction), as long as it doesn't touch the MMU or data cache registers. In terms of performance on most workloads the 030 is only slightly faster than the 020 at the same clock speed, but ScummVM might be one of those cases where the data cache helps a lot, so YMMV.

Are we still talking about running on an unmodified TG68 core?, meaning pure 68000 compatibility? That was my concern with the name ECS_030, but as long as ScummVM ECS wasn't compiled with a -m68020 flag or anything fancy it should run well on an unmodified TG68...or at least run

Hi, the TG68 core is unmodified

I think he was asking, if the tg68k is running pure 68000 opcodes, or was selected using 68020 instructions ...

[jbilander]

Yes, I was under the impression that the TG68 core was 68k instruction set only and not 68020. Looks like I was wrong, looking at the sysinfo screenshot on first page it says 68EC020. Sorry for the confusion.

The original version of TG68 (as used in early ports of Minimig to the DE1 and DE2 dev boards) was 68000 only. The newer version can be configured to support 68020 instructions - but it can still be configured for 68000-only, so you weren't entirely wrong.

For this project, though, it supports 68020 instructions.

Morning all,

Quick update. It may seem everything is quiet but there is lots of work going on in the background. Progress is good

Apart from ScummVM ECS another great thing to demo would be AmiWolf/AmiSpear ECS

Although these ports are labeled 'ECS' they will run fine on any Amiga with 64 color half-bright support.

Thanks for the links/info.

This week has been very productive and we are hoping to show the next phase this weekend, it is a very important development for the accelerator, and i am hoping it will be ready to show off.

Is there an FPS counter option on these ?

Update: https://www.mike-stirling.com/2020/0...-from-sd-card/

You can see from the URL what the key addition is. Still a bit of work to do to maximise potential but quite pleased with progress so far (and I've been busy with other work most of the time since the last update).

Excellent work! History in the making!

[utri007]

Nice! This would be nice product even current state!

We have quite a few more features to go yet... I think i know why the bootable SD card has not been done before, there was a lot of reading and some misinformation too.

Wouldn’t mind seeing an A1200 version of this card.
