Re: SAM Coupe core for MiST

Works OK with the newest core, too (20170206). Maybe jamesrc used older one? Or he has to update MiST firmware?

Re: SAM Coupe core for MiST

I can share Quazar Surround soundcard (playing stereo) if you want, or anybody else wants, there are lots of software to play with it. For now my skills are far from enough to mess with RAM, CPU clock etc. I have tried but with no success. And I have no idea why. But if it works with Amiga core, it ...

Re: SAM Coupe core for MiST

Unfortunately, i cannot increase CPU speed due to MiST using SDRAM. Unlike in other my cores where i could use FPGA RAM for video cache, SAM Coupe uses whole 512kb for video. So i had to use SDRAM for video. Since SDRAM require significantly longer time than SRAM to access the data, there is no tim...

Re: SAM Coupe core for MiST

Meanwhile I have added back AY to the newest core, this time with changed address. And It works, all the demos I have converted once work! Who would have thought, I had no idea about programing FPGA until today :D

Re: SAM Coupe core for MiST

Btw, did you check disk write ability? It works on some disks and doesn't on others. On these others I can do nothing, nither read nor write. I have the "87 Check disk in drive" error. I think it's the same disks that had a problem with booting in the earlier cores. Edit: Sorry, my mistak...

Re: SAM Coupe core for MiST

Mouse and SAM DAC work great! Thank you very much! Now let's go back to the hard disk support ;) There are some images from different people available on internet. The best example would be a collection of demos: http://sam.speccy.cz/al-software/sc-demos_collection_2014-11_atomlite.7z You can try it...

SAMDAC is 8-bit per channel, but in MOD player two Amiga 8-bit channels have to be mixed to one.

Re: SAM Coupe core for MiST

How can i be sure it was written correctly? When i was adding write ability to BK0011M i had there good file manager similar to Norton Commander. Just press F5 and copy as many files as i want. Then run these programs to check if they are still working. I can't remember any file manager for SAM, bu...

Re: SAM Coupe core for MiST

You can simply use BASIC (SAMDOS) commands. Insert the disk to the first drive and type 'boot 1' to load DOS without autorun. Then just type ' save "prog" ' for saving basic program (it can be even empty) or ' save "screen" screen$ ' to save screen. You can type dir or dir1 to c...

Re: SAM Coupe core for MiST

4) Can you provide the link for technical info about SAMDAC and LPTDAC? I also need software using both of these DACs. DAC (also named EDDAC) is a standard covox for SAM, connected to printer port. SAMDAC is a standard (?) stereo covox, with channels selected by STROBE signal. Short info about SAM ...

Re: SAM Coupe core for MiST

1) About mouse: As far as i know it's mapped to cursor keys. I don't think so. You can't use mouse instead of cursor keys in every software. It doesn't work. When you can use both (like in the games I have mentioned), you can move cursor much faster using mouse than using cursor keys, so it can't b...

wait... You want to say you simply use software inside ZX emulator? Why you do this instead using ZX core? Why? Because I can :D And I like it! I have my own collection of ZX Spectrum demos and games on SAM Coupe disks. I spent a lot of time on them in the 90's. For me it's more fun than ZX core. B...

Re: SAM Coupe core for MiST

2) About hard disks: You are right, hard disk is just a set of small partitions. But you can change the partition from SAM BASIC. It gives you some advantages. You can boot to the menu allowing to select and load proper disk by pressing just one key. Or you can load multi-disk program without changi...

Re: SAM Coupe core for MiST

Disk writes would be great. Of course there is software where you can use mouse, for example games: Lemmings, Batz'n'Balls etc. Other ideas of extra features are: Atom and/or Atom Lite harddisk support (.hdf files), stereo SAMDAC and/or mono DAC on LPT port (option to switch?). Personally I will mis...

It works! After removing R21 the sound is just like it should be! Thanks a lot! And I'm glad you have removed clicks, too. I have also checked other suspicious cases, but all seems to be fine. Now, are you opened for some useful extra features? For example Z80 at 20MHz. All the demos from DTA Softwa...

Great! I have to remove R21 and check. And also check if it fixes BTTP. If not, I'm going to record only the channel causing problems, using ETracker. The sound is not the only issue I've noticed, but I need to do more tests. For example something was wrong with booting disks (boot errors), but it s...
