Have you tried running the MiSTer binary from SSH and look for any error messages?

syn

Wow, that is awesome. With lightpen input from the oscilloscope? How is that even possible?

Hey all, I thought it would be interesting to run AROS m68k on the MiSTer. I got the boot floppy and iso from here: https://aros.sourceforge.io/nightly1.php The system boots and shows an AmigaDOS window, apparently it loads the AROS kickstart. 20240107_141801-screen.png 20240107_141805-screen.png After that, the screen flashes red & black. Conf...

The root "partition" is not a partition on your SD card. It is the "linux.img" file on your data partition under "linux". To mount that all you need to do is use the "mount" command on your Linux (or Windows with WSL) machine...

That's exactly what I needed to know. Thanks!

I have the MiSTer SD card plugged into my PC, but I can't mount the root partition. I can find only the MiSTer_Data partition.

There is a second 3MB partition on the card, but I'm unable to mount it. Linux doesn't seem to recognize the file system.

I need to fix something in /etc. How can I mount the root FS on the SD card?

I loved doing that on the PC on DOS as well. I wrote my own mouse handler routines, did audio DMA with my SoundBlaster Pro, wrote pixels directly to graphics memory... It's similar to microcontroller programming today, except the whole desktop computer was your Arduino. The Amiga was a little before my time, programming wise. I'm exploring it a bit...

Ich hab früher Assembler programmiert, aber nie auf dem Amiga. Durch den MiSTer bin ich drauf gekommen, mir m68k Assembler ein bisschen anzuschauen. Ich habe hier versucht, was ich bisher rausgefunden habe in einem Video zusammenzufassen.

Hey, that's a lot of ports. Want to try the MegaDrive version, see if it's really more fluid.

syn

No, I haven't even installed the Mega Drive yet. Or most of the other cores. There's a lot to explore...

...I played 3 games, in the 3 modes. League, Cup and Knockout. I beat the game on all of them. Which I could never do on the emulator (latency). Nor on the real Amiga 500 (too young).

I'm happy.

https://github.com/MiSTer-devel/Main_MiSTer/blob/2d40444af0327370c29ff3eb5937b189b79a55ca/input.cpp#L5339 The minimum delay between updates is 15ms (~ 66.7 fps). Which is a bit faster than the usual Amiga refresh rate of 50..60 fps. So it's possible that 2 updates get written before the Amiga polls it. Then the first one would get lost. I changed ...

Try enabling fast polling on usb, it will overclock it to 1000hz. You may need to adjust the mouse speed in the MiSTer.ini afterward. I tried. Didn't notice a change with or without 1000hz. If anything, 1000hz seems to make it a tiny bit worse. Checked different mice, too. Tried reducing the mouse speed ini setting too. Will decrease the mouse spe...

Digging around in the code a bit, I found this: https://github.com/MiSTer-devel/Main_MiSTer/blob/master/user_io.cpp#L3622 Mouse deltas are sent to the minimig core as 8-bit values, and if they are too large, they get clamped to -127...127. I inserted some printf statements there, and this code does get hit the moment I see the mouse jumping. Could...

There's an Aminet project to drive a PS/2-style mouse on a real Amiga. (https://aminet.net/package/docs/hard/ps2m) From their notes: - detection of Amiga mouse counters overrun: Amiga has only one-byte signed counters for mouse, and AmigaOS checks them only one time per vblank. This means that mouse may move only 127*VBlankFreq pixels per second (...

I just tried it with FS-UAE. I cannot reproduce the problem there, even moving the mouse as fast as I can. Mouse input is a bit laggy, and cursor movements speed looks slower, but there are no jagged movements like on the mister/minimig. Can't reproduce it on WinUAE either. Exactly the same: relatively slow, laggy mouse updates. No cursor jumping. ...

Your PC is huge a magnitude faster than the Minimig core, so its simply able to keep of with (and display) your recorded mouse movements at a greeter granularity.

The mouse jumping never happened on a real amiga though. Neither does it happen on an emulator.

Hey all, I finally got myself a MiSTer for christmas. All the parts have arrived, I have set up a lot of different cores, and I'm so amazed how awesome this project is. This is like a digital archive of all these great consoles, arcade machines, the Amiga... I have used emulators before, but I was always dissatisfied with the input latency. It just...
