It truly does, I keep one at all time in my main desk in the basement, besides my modern PC and my vintage IBM 486. My 4 year old loves to play Déjà Vu from Rubicon software (mostly on the Mac Plus), the memory tile matching game, not the ICOM visual adventure game. We love the sound clips it...

Again, I don't have the adapter, that image was taken off the net.

I've figured out (sometimes remembered) stuff:  -The color mode the Monitor is set to matters in terms of pixel depth and how much data is dedicated to it in System 7 when you attempt to do this direct data manipulation. Everything became easier when I set it to 1-bit B&W -I don't *need*...

Today, I can finally make the C-style manual copy work on both mini-vMac and a regular ol' hardware Mac Plus with satisfying fluidity - way bigger than I had with CopyBits. The GrafPort in BasII on my Win10 machine is stubborn and shows weird results and fills the top few lines with black...

Wait, don't these bitmaps work such as baseAddr points to the first int or long (however we want to parse it) associated with the top left area and progresses towards the bottom right in the normal English reading direction? Your code assumes the baseAddr is the very last one of the bitmap and...

edit - false alert

/* add left/32 and top*(512/32) */ register long *dest = ((long *) screenBits.baseAddr) + (dstRect.left >> 5) + (dstRect.top << 4); I'm getting crashes during the looping copy, as is standard C pointer fare :) I've tried long and hard and I can't wrap my mind around these...

Thanks for those tips. I more or less walked through the same topic about 15 years ago. Measuring ticks timings (with TickCount because I'm limiting myself to System 6) made this obvious because 2 CopyBits operations were ramping up in the 27 or so Ticks range (each 1/60th of a second). Taking...

Context: I'm trying to refresh a Mac Plus' whole screen 512x342 (for starters..., I will reduce that size going forward) by installing a VBL Task whose purpose is to CopyBits the contents of an offscreen bitmap to the screen bits of what is shown. Of course, the best way to do this is to limit...

I don't mean to be dense, I'm honestly curious, but first, here's where I'm coming from - 2 years ago, I noticed my best Mac Plus (platinum, 4 mb RAM) was no longer booting, so I recapped it and realized that the ROM was faulty, as I had another Mac Plus in working order, so a swap of the ROMs...

Things I had done after my post but before yours: -Make a BNDL resource with ID=128 -Transfer what I had in ICON to ICN# with ID=128 -Link the ICN# to the BNDL -Use a unique signature in the BNDL -Use the same signature in the whole resource file info, 'Creator' field -Check the 'Has...

I'd like for my built C application to have a custom icon polled from a resource file during the building step. I successfully did it some 15 years ago for a mock project I was doing, but I don't remember how I did it or what I'm missing. Here's what I'm using: 1) System 7.5.3 under Basilisk...

Phenomenal job! That's a lot of skills and equipment in many different areas to make this a reality. How do you find the emulation on a pi4? I notice the smoothness of the mouse cursor moving around is noticeably less than in real hardware. In many games, it's not a big issue, but for stuff...

I also have them, this is not about the adventure games from ICOM, I'll kindly redirect you to read the first post of this thread to see what this is about. 

Welp! Someone uploaded a cracked version in Mac Garden https://macintoshgarden.org/games/dejavu#comment-76349 The game of being the first to bring this to the world is done, but the fun of understanding how it was done is still on. Time to compare the apps side by side... That is, if I don't...

My first unsuccessful and naive attempt at thwarting the copy protection is to zero in on the PIRATED subroutine of CODE1, letting the first LINK instruction happen, and then swap in whatever was happening in the next two lines with an UNLINK (why not cancel the stack allocation that was...

I finally have time to resume working on this. I'll have so many questions. The only direct hands-on experience I have with assembly language is with a 6502 last year, when I made a silly little game on a breadboard 6502 kit computer (from Ben Eater, who made a great youtube series that...

I kinda understand where you're coming from. PC users had, right from 1987, the option of playing back real MIDI file through an adlib sound card, arguably the first hardware sound card worthy of mention which used Yamaha OPL chips. Even though it sounded like a joke for professional synthetizer...

No, Studio Session uses another proprietary format. Where a MIDI file played on synthetizers would typically call upon hardware to get to sampled instruments (often in ROM chips), Studio Session has a single freewave tone for each instrument saved on disk as an audio file, played back at various...

I wrote you on facebook in the Apple Enthusiast group, but I'll repost here for the sake of discussion here: You can't output MIDI from this. I always ranked the various very early music notation software in terms of capability in my mind in this way: Concertware: uses the 4-tone synthetizer...
