Re: MIST C64 core - 1541 Ultimate 2

Postby Paradroyd » Wed Oct 28, 2015 10:14 pm

This is interesting.. if you look at the bottom of this page on the 1541 Ultimate Interface 2 cart website, it states that the FPGA and software for the 1541 U2 are open source.

Granted, I don't know exactly what this means in this case, but it would be really cool to see at least some of the 1541 U2s features make it into some form of the C64 core at some point.

I've seem that a while ago. I don't exactly remember why i didn't try to include it. But i think it was simply overkill for my purposes.

What are the features you'd like to see?

I changed the links on that page to reflect the new home at github. And i removed most of the content as it was totally outdated, anyway.

You're right..a lot of it is either redundant or simply overkill.

Support for cart images and REU would be nice. Support for USB RS232 or maybe "emulating" user port based modem over an ethernet dongle would also be useful for BBSing, etc (for all I know this might already be supported in some form).

I have one. It really takes the C64 to a whole new level, especially the latest update that enables a multi-threaded FTP server directly to the SD card over Ethernet, independent of what the C64 itself is doing, more SID voices (8, I think), etc.

I think I asked this before but don't recall seeing a reply. Would it be possible to have the core recognize my Jiffy DOS ROMs?

just to be sure, because it's not mentioned in the wiki, the d64 images support is read-only, isn't it?

A few things that would be nice to support from the 1541 Ultimate would be G64 support, read/write on D64 and T64 support. There's a handful of games that flat out do not work on D64 such as Defender of the Crown. I haven't played with the core much but c64 fastloader support is also really handy if it isn't there i.e Epyx Fastloader.

Hi,

I use last C=64 core, and when I change to NTSC, I receive a "no signal" error in my monitor. With previous versions I didn't have any problem with NTSC mode. Have you experience any issues with the video modes?

Hi,

Is it possible to use some software speedloader for D64 access?

Best regards,
Goran

I don't get that, but there is definitely something different with it now. I'm running on the 160221 firmware that was zipped with the latest AGA amiga core by Chaos and the latest C64 core.

I simultaneously run video split to a small CRT and a Dell Flat panel. Flipping back and forth between NTSC & PAL in the OSD sometimes results in an out of sync video display on the CRT, and the flat panel is shifted way off center both horizontally and vertically. Flipping back and forth a few more times will usually center/sync everything again (at least on my stuff).

Could a save feature be added similar to the way the MCC-216 C64 core uses?
The MCC doesn't automatically save but shows on screen when a save is required and you push a key on the keyboard then the data is saved to disk. Sorry I don't have more details.

Yes but the question really is, how does the MCC actually emulate a 1541 (or just a wirteable disk drive in its fpga core)

Do you know if it's possible to add cartridge (.crt) support? :)

Probably but it seems the current c64 core is abandoned other than the work Sorgelig has done to fix some of the more glaring problems (NTSC timing/SID).. AFAIK the c64 core source became closed after a certain revision {later versions contains code from the Chameleon project} and the author isn't sharing any of the more recent updates / enhancements.. I could be wrong but thats my understanding of the current status ...

Thanks for your answer ericgus. Actually is one of the few features I miss on this core, and the compatibility with Simpsons Arcade game ;).

We should start another poll .. "Which CORES need love" .. for existing cores that are .. more or less "abandoned" and really need a little help.. i.e. the PlusTOO core could really use a functional Mist configuration save ability .. C64 .. "Write" enable on the 1541 emulation.. etc..

Great idea. I would like to see the Atari 2600 updated to use larger cartridges. There are many Homebrews I would like to play but can't until larger carts are supported.

I bought the new digital version of Sam's Journey and it works very well on FPGA64 Core for our MiST.

This is a new fantastic platform game for Commdore machine.
Highly Recommended !
