Minimig (Amiga) core discussion

Tried it. The version of AFT2 I have works in WinUAE.

Is that the same one that is not working on MiSTer?

[schroediman]

I don't know, I never reported that AFT2 doesn't work on MiSTer.
I just had AMOS lying around and my two real Amigas to read out the register.
But now I tried it on MiSTer, too.
And there it hangs. Right after the intro. With a single colored screen (most of the time red).

There seems to be lots of artifacts in some games like Risky Woods, SWIV, and Jim Power, I think we might be due to a lost the cpu_custom in cachecfg in this commit:
https://github.com/MiSTer-devel/Minimig ... 0d7f3923f1

since it originally was added in this commit:
https://github.com/MiSTer-devel/Minimig ... 0a04a846a2

I can't test this week, but I figured that replacing line 426 in minimig.v https://github.com/MiSTer-devel/Minimig ... mig.v#L426:
assign cachecfg = {cachecfg_pre[2], ~ovl, ~ovl};
with:
assign cachecfg = {cachecfg_pre[2], ~ovl, (!ovl && cpu_custom)};

could do the trick. I appreciate any help with this, thanks!

I'm having a very hard time finding where the DEL key should be mapped on my German keyboard.
It is not mapped to "Entf" as usual.

Is there some way to redefine the keys in the Minimig core, without first having to press the key (as in OSD).

edit: was able to fix this by installing the keymap in workbench

hi

what do you think about this error ?

20200329_123732-screen.png

is it fpu related ?

Could it be this? I don't know which CPU you are emulating.

[breiztiger]

CPU : 68020
D-CACHE : ON
CHIPSET : AGA
CHIP : 2M
FAST : 384M
SLOW : NONE

I've been working on setting up a custom HDF file (wow, didn't press the RDB button with the first one, that results in different drive contents between MiSTer using the image locally and WinUAE mounting the exact same drive image over Samba, super confusing).
Just tried a couple of demos and get this exact same error, mixed with some of the demos saying they need a FPU. I actually just found a discussion mentioning exactly that: http://92.222.181.53/viewtopic.php?t=37146&start=75

I also installed my Candy Factory Pro software and man is it slow, which is probably correct for a slower CPU without FPU, as it relies on the floating point libraries to emulate an FPU. I hope the Minimig core will get an FPU some day.

[breiztiger]

i test my hdf in winuae with same cpu and no fpu, it work

Okay, that is odd. I got the exact same result with the MiniMig and WinUAE when I set WinUAE to 68020 without FPU.

[system72]

has anyone had any luck connecting to the net through minimig?
i believe i read somewhere this is possible.
seems like a convenient way for downloading/installing new files rather than editing the .hdf through winuae.
not sure how to go about trying it exactly though...

Serial UART is suitable for small files --> http://www.atari-forum.com/viewtopic.ph ... 7&p=343001

For larger files, you can also "mount" an HDF in the Linux filesystem and FTP them in. Care must be taken to properly "umount" the HDF or it will get corrupted.

The HDF has to be formatted with the OFS (Old File System). That's the only Amiga filesystem that Linux can mount.

I use a dedicated 1GB HDF formatted with FFS (Fast File System) for this purpose. That way if it gets corrupted I just reformat it - that will happen if you forget to unmount before rebooting. I'm quite sure I use FFS.

hi

https://www.pouet.net/prod.php?which=4324

doesn't start with stock amiga 1200 config (ROM : 3.1 CPU : 68020 D-CACHE : OFF CHIPSET : AGA CHIP : 2M FAST : NONE SLOW : NONE)

just first counter (loading) and crash

[DrOG]

If I remember correctly D-CACHE should be set to ON if you want a stock A1200... Other settings are fine in my opinion.

EDIT: Sorry, my bad, you're right! Stock 68020 has no D-Cache...

Did you see the comment there about the zoom packer?

[breiztiger]

my adf start good in mame or winuae

i think it's the first release that have this problem

Interesting, that is a good find then, Minimig is quite mature, so a problem like this must be rare. I hope it will lead to a fix in the core.

It says it needs the ESC chipset, configure it like an Amiga 500 plus or 600: 68000, ECS chipset, Kickstart 2.0, 1MB chip mem. Then it needs some extra memory, so add 2MB of fast mem. I have it working here.

[breiztiger]

No it’s write

Configuration requise:
OCS 1 Mo Chip + 1 Mo Fast
14 Mhz

How can you Have 14mhz 500 core

do you have enter the game ? when i configure with 68000 OCS 1Mo CHIP 2MO FAST (can't 1MO) FLOPPY DISK TURBO OFF, after inserted disk 2, i can view title screen but just after return to cli 1>

Yeah, I played it, it worked fine. I had the second disk in the second drive already. Are you using Kickstart 2?
EDIT: Just tried it with 68020 selected, also works fine, might be a bit more smooth.

[breiztiger]

it's because of kickstart 2.04 (A500+)

work with 2.05 (A600)

thanks you

ps : if someone can test on a real 500+ with 2.04 to confirms
