Generally speaking as a platform, the Amiga, unlike other machines of its era, was not entirely dependent on the CPU/cpu speed so speeding up/slowing down the CPU isn't going to be as massive a noticeable impact as say with other machines (of course this depends on the task at hand, games vs say 3d rendering), the custom chips kind run along at the...

Yeah, pretty fast for a 68(EC)020 CPU.

These talks come up about once a year and the all end the same way.. once people realize the actual "cost" to make a Mister 2.0 .. the project usually dies and fades away.. I suspect the same will happen here. How does anything get moving in an 'adhocracy' community - interesting ideas and enough support to make it happen. To answer that...

@StatMat Thanks for your amazing work, diehard fan here. If i can, i would suggest to go back to divide the oneload files by folders and letters, this one is a bit messy in my opinion. Kind regards and keep up the good work ! Yea, for example I was trying to find "KnightGames" and I had to dig a bit to actually find it .. it was there ju...

In the same vein id love to see the "PENULTIMATE+ CARTRIDGE" from TFW8B able to run on the Mister .. one thing I do miss using my Mister vs my real Vic20 .. The mega-cart does everything the Penultimate does and more (apart from the TFW8B) games. A pity you can't really obtain them any more. Yea but I thought the Pent did more now .. cou...

Yes, it's in the README

Ok thank you .. guess I did miss it ..

ericgus09

Can you flip/flop between the VIC chip output and the VDC output? .. some games support dual screen .. was curious if this is supported.. maybe I missed it. Im not talking at boot/start but during running ..

ericgus09

Thanks for the info and updates.. !

ericgus09

In the attachment you'll find the .rbf for the core, and a modified MiSTer main binary because the core needs changes to that for the 157x changes. Disk I/O won't work without the modified main binary. Im just curious .. I often see cores mention changes to the main mister binary frequently .. usually in reference to disk support, can you maybe el...

Been on Mastodon for a while, mostly been like talking out into the void. Would like to see some profiles and see if it catches on. You should take advantage of your local feed .. mastodon puts a little more requirement on the user to discover things .. there is no algorithm .. you are it. Some good tips here for newcomers.. https://techcrunch.com...

thanks

Only use case I can see right now is for people who want to play with that new CommodoreOS ..

Oh im not talking c64 core only but all kinds of cores, the minimig core etc.. its kinda his thing and not unique to only one core.. its a pattern.. lol..

ericgus09

I can remember Sorg stating on the FB group he thought it would fit on the DE-10 but saw no point in porting it Yea he's like that bout a lot of things .. he says no .. then it ends up happening anyway.. often he only sees it from his personal perspective only then comes to understand the benefits or how it appeals /is good for a larger audience ....

ericgus09

Oh if its done on the mister linux side alone (eg not in the fpga) then it should be a much simpler affair..

ericgus09

Oh I know what SD2IEC does and why C64OS needs it, im just trying to see if there are other programs/uses cases beyond just the one "c64os" to help build a case for why it should be added and what benefits it would bring beyond what we got now.

ericgus09

Yea, I can see IDE64 emulation .. there are a few use cases for that one for sure.. if it could be implemented. It just makes a better proposition/argument if you can state a benefit for multiple reasons then one limited audience program.. Just trying to look for a justification that gives reason beyond what analog features are already there .. eg ...

ericgus09

Thanks for the info chaps, much appreciated. Without breaking any rules about requesting/posting roms, have these two carts been dumped so if someone were looking to implement multicart loading into the core they could test these two? I can see that the MegaCart is out in the wild, and that one is confirmed to run on MiST. I dont know bout the car...

ericgus09

While I get adding SD2IEC to the mister Commodores 8 bits makes some sense .. in reality there isn't much actual benefit over whats there now aside from letting people run C64OS and honestly its not that impressive .. maybe I just don't get it but it seems like a neat tech demo novelty that wont have much long term value .. While I wouldnt ever tak...

ericgus09

Does anyone have a list of what VIC-20 multicarts are out there? Are there exclusive contents on any carts? The more info there is on what is out there then the more chance of getting support added. Well the Penultimate+ cart has these TFWB in-house games included on their cart (and yes they are decent games), I actually own 2 of these carts, the ...

Well I can say from personal experience that running Geos at 48mhz on the Ultimate 64 is a surreal experience, having full access to a higher display modes will be VERY INTERESTING for sure..

Looking forward to it..

However I have found the signal NMI_SYNC inside the CPU, which I believe I can expose to the rest of the core to give it an NMI ACK. We'll see soon enough.

And there in lies the magic of FPGA..

ericgus09

I think you might see "fantasy" machines/consoles get created .. someone taking bits and parts from a number of preexisting cores and creating something new that never existed before .. or say taking an existing core and adding all kinds of enhancements to it that radically change it in many ways.. I think we haven't even really touched t...

ericgus09

I still think calling it a "C129DX SuperCPU " might be a better option or something, something that specifically doesn't have 128 in the name .. just kinda avoid the entire "128" thing .. I think you will save yourself a lot of repeated comments explaining what it is and why some copy protected C128 game doesnt work on it ... Im...

ericgus09

It's already called C128DX, which seems enough to differentiate it from the "normal" C128 cores (of which there are now 2 under development). Ha apparently not different enough as I, my self, got confused today on the two different threads.. The reason I called it C128DX, is because the C65 was originally called the C64DX. :) Since this ...

Or the MEGA65. Some people like fantasy hardware, it's not my thing but I don't see why some like to complain so much about it. Let Alynna make his C128 successor. Sure .. though it might be helpful to give this fantasy machine its own designation ala Mega65 .. perhaps the 256C ? .. Its still neat .. and very much a "what if" machine for...
