XCODE NUMPAD EMULATOR CODE THAT WAS

For server-side requirements, you can read Server Support. There has however been some bits of progress, which are summarized in this post:On macOS, the autoUpdater module is built upon Squirrel.Mac, meaning you dont need any special setup to make it work. You will then see two windows one is the emulated Macintosh machine while the other shows various log messages: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. Here mac-se.cfg is the name of the config file to be loaded (-c) and run in the emulator (-r) with results written to the log file (-l) in verbose mode (-v). Pce-macplus -v -c mac-se.cfg -l pce.log -r.

Xcode Numpad Emulator Code That Was

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) 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.There were two critical fixes in the TextEdit, one of which caused at least one of Marathon terminals to crash: 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.

(Also, Toni was able to complete the full FoolвЂ™s Errand playthrough on Twitch using this improved version).This year we also celebrated the official Star Wars day (May the 4th) by trying out how the BrГёderbundвЂ™s Star Wars arcade gameвЂ™s Mac port works on M.A.C.E. Before starting the FoolвЂ™s Errand finaleвЂ¦While implementing this, we found a minor byteswap bug in Launch trapвЂ™s handling of AppParmHandle. The quickly hacked and very rough MiniLauncher, used for The FoolвЂ™s Errand playthrough 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).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. The original game used a separate application for prologue, and also a dynamically generated file for viewing the finale after completing the game.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.

Also, it has some timing glitches at least in cutscenes, which may be related to the timer issues with Prince of Persia 2 and Loony Labyrinth (which need more investigation).Another task from long time ago was implementing the hilite transfer mode for Color QuickDraw. This caused the inverse color lookup table to not update properly, turning at least the pile of monkeys in Monkey Island about box from grayscale to black & white рџ™‚It seems that Monkey Island runs quite well now on the emulator, although doesnвЂ™t yet have any sounds until the Sound Manager implementation gets finished. ReserveEntry palette manager trap had a bug where the GDeviceвЂ™s color table was not reseeded when clearing the вЂњreserveвЂќ (only when setting it). The Start Manager traps GetVideoDefault and SetVideoDefault traps were needed, and it seems the the dummy implementations were good enough to make Monkey Island happy There were a couple tweaks needed to get it to run: The вЂњmain menuвЂќ of the game did seem to run a bit faster than on real Macs, but luckily the actual ingame play was not affected by machine speed, and ran just fine.Inspired by the number of people recently streaming Monkey Island on Twitch, we were interested to see how the Mac version of that game would run on M.A.C.E.

It turns out that game is very strangely using some of the unused 68K user exception vectors to save handle to data being used to track music/audio playback in their VBL handler.The reason this didnвЂ™t work, is that all those vectors were originally uninitialized (set to zero), and this particular version SierraвЂ™s AGI engine checked if the exception vector pointer was set to a value above ROMBase, and it being lower assumed some handler was already present, and skipped using it for its own data. Hilite in TeachTextвЂ™s TextEdit text areaAdditionally, the hilite mode was also one missing piece of the scrollbar CDEF thumbnail drag drawing code, so that is now also visualized correctly.The mysterious stuff in Sierra games #1: Sound in Mixed-Up Mother GooseAlthough KingвЂ™s Quest 1 was already working nicely since last year, Mixed-Up Mother Goose was interestingly having trouble playing audio, so we did a bit of investigation about it. If using the hilite transfer mode of 50 or 58 (or when the special hilitebit in HiliteMode low-memory global is cleared in combination of using xor transfer mode), QuickDraw will swap background and hiliteColor with each other, producing toggleable highlight coloring:

It should be noted that even in 24-bit mode, at least QuickDraw handles the actual video memory access in 32-bit mode by using SwapMMUMode to temporarily switch the mode вЂ“ same thing that some 24-bit compatible early color games also do, such as Maelstrom.In our emulator, as we ran everything in pure 24-bit mode, including the video memory access, we didnвЂ™t care about the high byte of the address, which being zero originally displayed the same behaviour. On the first try, the same problem manifested also in M.A.C.E., so we started to dig a little bit deeper to find the cause of this, and found something interesting.When I dissected the AGI code in Space Quest 1, I noticed that really weirdly, as the very first thing, the game checks if the the baseAddr of screenBits is above $F000 0000 вЂ“ and if this check failed, even if the screen would be set to higher bit depth, it would go on and assume it was displaying the game on a monochrome screen.As the problem on other Mac emulators may be partially related to inability of switching to 24-bit mode (at least when I tried it with Basilisk II), I believe that what is happening is that Slot Manager addresses the cards in different way in 24- vs 32-bit modes (for example, card $9 is accessed through вЂњminor slot spaceвЂќ range of $009x xxxx, which translates to 32-bit address range in вЂњstandard slot spaceвЂќ of $F90x xxxx вЂ“ problem is, that in 32-bit mode, the address would be in вЂњsuper slot spaceвЂќ of $9xxx xxxx). Mixed-Up Mother Goose (with audio working)The mysterious stuff in Sierra games #2: Color supportOne of ToniвЂ™s friends on Twitch mentioned that some Sierra AGI games had problems running the 16-color versions in Mac emulators (specifically Space Quest 1), so we were curious and investigated this issue. By adding a dummy exception handler and populating all the exception vectors, Mixed-Up Mother Goose was able to play music & sounds without any problems (Toni also did a one-hour playthrough of this game on Twitch to celebrate this fix).

As itвЂ™s so far the only game that requires Thread Manager, it was previously put on a hold due to uncertainty about how much threading features it would be using.
