I can play games but only with kickstartrom 1.2 and 1.3 roms, the Atari 1200 or later kickstart (2.1 3.1 etc) roms doesnt work.
Is this ok? I have the last rtf mister version and firmware.upg files in main sd .

Can mister run 1200 or later kickstart rom? how to do that?
thanks

I would suggest an 512K Amiga 1200 3.1 ROM... maybe "Atari 1200" is just a typo?

Also, I think "firmware.upg" is something for MiST, not MiSTer...

Here is a link to the forum thread about the updater script --> viewtopic.php?f=117&t=35427

Ok thankss, I'm just following the readme from official mister page amiga,its says someting about firwamre.upg.

About kick.rom, I have tried all 3.1 A1200 kick.rom from a big file of kick roms that I have downloaded.

Kickstart v3.1 rev 40.68 (1993)(Commodore)(A1200)[h ShapeShifter]
Kickstart v3.1 rev 40.69 (1993)(Commodore)(A1200)[h Harry Sintonen]
Kickstart v3.1 rev 40.63 (1993)(Commodore)(A500-A600-A2000)


[b]Can you tell me the exact name of the best optimized kick.rom for mister that I have to use?
thanks


EDIT:I have found a 512kb 3.0 rom that it works, I this optimized for mister?

Glaurung is right, the README.md at https://github.com/MiSTer-devel/Minimig ... /README.md says:
Software
FPGA core releases can be found here [http://somuch.guru/minimig/minimig-mist/]. The latest release available is minimig-mist-1_2. The zip file contains a minimig-mist-1_2.rbf file, which is the FPGA core, and a firmware.upg file, which can be used to upgrade the firmware on the ARM microcontroller (usually, there is no need to upgrade the firmware, unless it is specifically mentioned to do so). Both files should be placed on the root of your SD card. If you want this core to be the default, you need to rename it to core.rbf.
It should probably be updated.

@glaurung: These are the recommended configs:
Recommended minimig config
for ECS games / demos : CPU = 68000, Turbo=NONE, Chipset=ECS, chipRAM=0.5MB, slowRAM=0.5MB, Kickstart 1.3
for AGA games / demos : CPU = 68020, Turbo=NONE, Chipset=AGA, chipRAM=2MB, slowRAM=0MB, fastRAM=24MB, Kickstart 3.1 For Workbench usage, you can try turning TURBO=BOTH for a little speed increase.

There are no optimized for MiSTer kickroms. The ones you can buy from Cloanto work for me, including 3.1 on a Amiga 1200 config.

The "ShapeShifter" ROM has probably been modified for use with the MAC emulator "ShapeShifter" which does not work on MiSTer Minimig core... It probably replaces the "prepareemu" command.

"Harry Sintonen" is an Amiga programmer known as "Piru" but there is no telling what customizations that ROM has, but you probably don't want to use that either.

The optimum ROM for compatibility is an 512KB Amiga 1200 3.1 ROM like the one that comes with the "Amiga Forever" package (from Cloanto). You can continue to use the 3.0 ROM, but you may run into problems...

Im not being lucky finding a 3.1 rom that work.
I there any free 3.1 rom that works?

No and afaik Cloanto holds the rights to these kickstarts so we cannot help you find pirated copies. The kickstarts from their Amiga Forever Plus package work https://www.amigaforever.com/plus/

The Value Edition does not come with 3.x kickroms, so Plus is the smallest package having all the ROMs you want. In addition you get legal Workbench images and other goodies, like the original boingball demo disk as adf

Good find! That package seems new? But yes, that is all he needs.

Its been around for a while, but just not well-publicized. --> viewtopic.php?f=117&t=32761&start=550#p371978

They probably would prefer you to buy the more expensive package :)

It has all ROMS, but I think it only comes with Workbench 1.3 and not 3.1 ADFs so that may be an issue if you are trying to build a hard disk image.

Ok I have bought it from android and put in my sd folder.
Works perfect 3.1 (with the encrypted rom.key file)

I know I can get it from internet for free, but anyway, 2€ is a just a coffee, so Its ok.

So the Android version still uses encrypted ROMs? Good to know.

Glad you got it working! :)

Being an IBM guy back in the day I didnt have the joys of the workbench and hardware.... just my mate booting the gamey goodness. So although I get most the theory from the emulation side of it with roms, kicks and workbench... when it comes to the real HW, I can get a little lost.

I picked up the updated 3.1.4 a while back for a project. However, I never got around to making magic...

http://hyperion-entertainment.com/index ... migaos-314

What interested me was the ability for larger files and folders etc (please excuse my terminology). Allowing for a more complete workbench experience.


What I'm asking is, can this be implemented if I start to configure it and if so, is it actually useful in this type of scenario?

It's unclear what you want.

At the moment just to know if 3.1.4 is compatible with this core?

With the larger HD and floppy support, it would come in useful for me. Please excuse my ignorance with the HW side of this, up until now its been emu based.

What do you mean with "runs better"??

I just realised that some games like Maniac Mansion ask me to change disk several times (on WB 1.3). I dont remember Amiga500 doing that in the past... :shrug:

You mean FPGA compiler RNG seed? If so, then sounds bad that we are depending on RNG to get stable build. :cry:

Sorgelig wrote:And of course cooling for de10 reduces such tolerances.

Can you please elaborate more on this? Is DE10 going to down-clock when temperature reaches some junction point thus some observe instability why other not?

Btw. I am running 32MB SDRAM that passes stability test at 160MHz for 20 min with a fan mounted on IO board v5.6, and I get graphics corruption as depicted by the others right there in the Kickstart screen on Minimig_20191013, whereas Minimig_20191007 works well.

would adding akiko and iso support in core be hard work to get full cd32 running or can it run via cd32 emulator via ide fix?

Ono, good job on narrowing down the time frame on the change that introduced graphical glitches (intermittent horizontal lines). I just tried a couple of games reported to show glitches, and 20191007 shows no glitching, but it gives me random freezes of my de10 (yeah... the menu is not working) if I set my fast memory above the physical 32MB that I have on my MiSTer.

I just noticed that I've not pulled into my dev tree the last commit, that relaxes the timings. I'm going to build it, test it and report back.

I've built the latest one, and tested and it looks good. No sign of the glitches. :cheers:

On the real Hardware of an AMIGA 1200, the CD32 is 100% compatible "with the musics" thanks to SIMCD32 and the compilation of the Kickstart CD32 1MB, and by adding Amiga Boot Selector 2, you boot directly on the CD32, I do not doubt that one day this Kickstart will be compatible on the MiSTer.

Pinball Illusion also relays on CMP2 (or CAS2 - i don't remember).

Actually that works for me with Retrofun's TRAPV implementation.

Didn't realize that my TRAPV fix made Pinball Illusion work, because it depends on the correct Fitter settings (for the MiST core). It worked with your core, but with the cores I synthesized it didn't. Found the correct Fitter settings and can confirm Pinball Illusions now works! :mrgreen:

Some Kickstart ROMs are optimized for 68020. They will not work when you try to run them with a 68000/68010.
See https://cloanto.com/amiga/roms/ for an overview and checksums for several Kickstart ROM versions.
