SIMH – Old Computer Emulator
It sounds like there was a config option available to disable the signature addition to the image file ( https://github.com/simh/simh/issues/1059#issuecomment-108689... ). I could see a benefits for having an embedded image signature for preservation and corruption detection issues.
I don't think complaining about the design is toxic, but recruiting uninvolved people on twitter, and harassing out of ban certainly is. Also reading the bug thread it seems the person with the issue wasn't the same as the one who instigated the harasment. (https://github.com/simh/simh/issues/1059#issuecomment-108675...)

Multics Simulator
Perhaps, however, SIMH (http://simh.trailing-edge.com/, https://opensimh.org/) also calls itself a simulator rather than an emulator. Six of one, half dozen of the other, I guess!
- Mystery? Of the few 1968 Honeywell Kitchen (Pedestal )Computers built, where are they now?

Anyone know how to attach a network device to a simulated VAX in simh?
I looked into this recently too, given the large amount of instructions at https://github.com/simh/simh/blob/master/0readme_ethernet.txt I decided it was too much bother for now.

Pico_1140: A PDP11/40 emulator that will run Unix v5/v6 on a Raspberry Pi Pico
In case anyone was wondering:
> The de facto emulator for most old computers is Simh https://github.com/simh/simh. The size and complexity of the individual machine apps is such that a direct port to a memory limited system is not feasible.

GCC gets a new frontend for Rust
VAX has its die hard fans, and the historical value of the VAX and what it did to shape our computing world can't be overstated. As both a learning tool and a way to preserve history, simh and VAX emulation are wonderfully accessible. VAX running modern NetBSD does an excellent job illustrating where performance regressions happen and where bad assumptions are made. None of these are compelling reasons to target a new toolchain to a classic architecture by themselves, but the interest is there.

Zork compiled from MDL source code
A long time ago you posted a suggestion in the original SIMH GitHub as an issue to have Interlan NI1010A added. https://github.com/simh/simh/issues/380

DreamShell: Operating System for the Sega Dreamcast
FTA:
"DreamShell
The Dreamshell is the operating system for the Sega Dreamcast based on the KallistiOS[0] kernel. It has a dynamic loadable modular system and interface for creating applications with XML UI and both C/C++ and Lua script on. You can see examples in ready-made applications and modules, drivers for various devices, formats and interfaces. Examples for audio and video decoding, compression, packaging, binding, network, emulation, scripts and more. From hardcore low-level assembler to high-level applications. There are also large subproject is the ISO Loader, which contains emulation of BIOS system calls, CDDA playback and VMU, also it can hooking interrupts for various SDKs and more."
"KallistiOS is an unofficial development kit for the SEGA Dreamcast game console with some support for the NAOMI and NAOMI 2 arcade boards.
KOS was developed from scratch over the internet by a group of free software developers and has no relation to the official Sega Katana or Microsoft Windows CE Dreamcast development kits. This has allowed it to fuel a thriving Dreamcast homebrew scene, powering many commercial releases for the platform over the years. It supports a significant portion of the Dreamcast's hardware capabilities and a wide variety of peripherals, accessories, and add-ons for the console, including custom hardware modifications that have been created by the scene.
Despite the console's age, KOS offers an extremely modern, programmer-friendly development environment. Using the latest GCC toolchain, it supports the entirety of C17 and C++20 including their standard libraries, along with support for portions of C23, C++23, Objective-C, and various POSIX APIs. Additionally, KOS-ports offers a rich set of add-on libraries such as SDL, OpenGL, OpenAL, and Lua for the platform."[0]

How would I go about making my own game for the Dreamcast?
You’re going to want to use KallistiOS to get started: https://github.com/KallistiOS/KallistiOS. It’s essentially a pseudo-OS for the Dreamcast that provides a lot of Linux-like functions.
What are some alternatives?
