Re: Transfering Commodore 128 Core

Isn't it possible to structure both projects in a way that the 128 core can include the 64 core as a git submodule?

Re: Rolling Picture on Commodore 1084S-P1

I don't think this mod is necessary. I also got the RGB SCART to 1084 cable, and this works on a real SNES and Mega Drive without problems.

Re: Rolling Picture on Commodore 1084S-P1

So I hacked together an adapter with the following pinout: DB9 VGA 1 - 5-8, 10 2 - 5-8, 10 3 - 1 4 - 2 5 - 3 6 7 8 - (R470) 13 9 - (R470) 14 1084sp1-adapter.jpg (I only connected one ground pin on the VGA side, since they are bridged on the I/O board) And what can I say? It is working! :) So I can modify the cable now to match that adapter. @rickda...

Re: PlayStation Based Arcade Hardware

For Tetris there is a ROM hack for running this on a PlayStation: https://www.romhacking.net/hacks/5607/
I expect that using existing patches is a smaller effort than making a MiSTer core for each PlayStation-based arcade hardware.

Re: Rolling Picture on Commodore 1084S-P1

So from above mentioned website I got the 1084S-P1 RGB pinout: 1084S-P1_connector_pinout.jpg And the pinout for the MiSTer RGB from Hardware_MiSTer : mister-io.png I measured the cable, and the RGB pins and ground are ok. Now to the pins which confuse me: 1. Pin 14 VGA connects to pin 6 DB9 with 10 Ohms resistance. On the 1084 pin 6 is unused. On t...

The switches should be okay, I toggled all of them without success. And the same switch configuration is working with my Amiga 600.

Thank you, but this did not help. I am now using a stock configuration file from https://github.com/MiSTer-devel/Main_Mi ... MiSTer.ini with only changing

But still no stable image. :cry:

Rolling Picture on Commodore 1084S-P1

Hi, I bought an analog I/O board and a 1084S cable from ultimatemister.com and connected it to my Commodore 1084S-P1. I configured the parameters as listed in the cable description, but I only get a vertically rolling picture in the menu. I played around with the settings and even set up a new SD card from scratch, but nothing changes. The monitor ...

Re: NTSC 1084 Monitor

Does this require the I/O board? If yes, this should be mentioned/linked in the description.

Re: MiSTer PCXT

Thanks for your input so far. I had no success with the CBM PC-I, but I got the CBM PC-10 BIOS to boot after padding the file with 32kb of zeros at the beginning:
pcxt-pc10.jpg
pcxt-pc10.jpg (284.75 KiB) Viewed 5591 times
So that was half a success. I learned that this is not a good idea at all and will stop further approaches. :D

Re: MiSTer PCXT

No, it isn't. Right now only the XTIDE ROM is supported, and supporting other BIOS may be difficult as it has features needed to make the HDD work with the core. This does not seem to be true. In the SW-Folder there are 3 make_boot_with_*.py scripts from which I could generate BIOS files (like the IBM 5160). Having success with booting these was b...

Re: MiSTer PCXT

I've got the case of an old Commodore PC-I in which I plan to put my MiSTer. Is it possible to load its BIOS into the PCXT core? The ROM files are here: http://www.zimmers.net/anonftp/pub/cbm- ... index.html

Re: Real floppy drive

Can't you use https://github.com/keirf/Greaseweazle for this, so the hardware-side floppy drive to USB interfacing is already solved and you "only" need to implement the software part?

Re: Kodi

Wouldn't this work with the FPGA handling the video decoding? At least there seem to be some commercial implementations for that:
