(Also, Toni was able to complete the full FoolвЂ™s Errand playthrough on Twitch using this improved version). While implementing this, we found a minor byteswap bug in Launch trapвЂ™s handling of AppParmHandle.

Before starting the FoolвЂ™s Errand finaleвЂ¦.

The quickly hacked and very rough MiniLauncher, used for The FoolвЂ™s Errand playthrough.

Right now the Minilauncher is very primitive and a quick hack to support this one single game, but we plan to improve it later to a more reusable launch tool, probably similar to AppleвЂ™s old MiniFinder, to use as a stopgap tool for the first general-purpose version of M.A.C.E. For this purpose, we hacked very quickly a вЂњMiniLauncherвЂќ tool, which allows not only selecting the launch application, but also passing a document in launch parameters вЂ“ which is required to show the finale (as clicking вЂњShow finaleвЂќ on Macs actually launches вЂњprologue вЂ“ finaleвЂќ application passing the вЂњShow finaleвЂќ as opened document to it). On real Macs they were opened using Finder, but we needed to have an easy-to-use way to open them when running the emulator from the single-click app bundle. The original game used a separate application for prologue, and also a dynamically generated file for viewing the finale after completing the game.

Most of code needed to support running The FoolвЂ™s Errand was already implemented long time ago, but one of the most important things, a way to display the prologue and finale was missing.

Minor fixes to allow streaming of The FoolвЂ™s Errand With these fixes, this particular Marathon terminal is now working without crashes вЂ“ and looks identical to the one on real Macs: The previously crashed Marathon terminal that works now

TESetStyle was calling TESelView with an invalid pointer.

In styled text line height table handling code, the code that was used to zero newly added line heights (when adding new lines) was not working properly in the case number of lines was reduced (causing it to try to clear a negative number of lines, wrapping around to a crazy number).

There were two critical fixes in the TextEdit, one of which caused at least one of Marathon terminals to crash: However, in some cases, clicks are still present in the audio, mostly due to the way how original hardware handles square-wave and sampled sound as a mix of both unsigned and signed 8-bit samples (that is, square wave sound amplitude ranges from 0 to 255, while in same buffer, sampled sounds are in range -128 to 127, with different вЂњsilentвЂќ baseline level. By allocating the SDL2 audio buffer in default native format (usually 44100hz), and upsampling the audio data in emulator, most of this problem was eliminated.

Even though it worked on Mac Pro, for example on M1 Macs it caused the audio in other applications to start cracking and breaking up. Originally the audio buffer with 22255 Hz sample rate was passed directly to SDL2, which caused some problems as some systems were not able to handle that format very well.

There has however been some bits of progress, which are summarized in this post:Д®ven though Sound Manager support is still under development (with relatively good progress), the audio support for вЂњClassicвЂќ type audio (that is, the emulation of audio hardware of Mac 128K through Plus/SE/Classic series machines) has been improved a bit. For the past half year progress has been a bit more slower than usually, mostly due to Toni being busy with the daily work, playing around on Twitch, and experimenting with his retro raycaster 3D engine prototype, while Pekka has been busy with work and private stuff.
