A lot of the older games really want to be booted off of a floppy disk and have various conniptions otherwise. Dark Castle I think might want Finder rather than MultiFinder (the default for System 6). Might want to use the Special > Set Startup... to switch to Finder and see if that gets you going. Most games on the image require nothing other than...

Thanks. Sorry been a very very long time since I used a Macintosh at college. Still trying to remember how to use it. I hadn't spotted the readme on the MacPack drive. Edit: Having said that, when I double click on the readme icon on the MacPack drive I get a dialog saying "Sorry, a system error occurred. unimplemented trap" with a bomb ...

I have download the mac pack and copied it to my sd card. The Macplus core starts up fine and boots to the OS (which seems to be system 7.5). I eventually found dark castle on the supplementary disk in the system 6 folder. So I assume this only works with system 6 (it crashes when I ran it). How do I boot into system 6? You could use the System Pi...

Fantastic work.

Heads up, I recommend against trying to play the game located at MacPack/Games/1985/Translyvania™. Damn thing might blow up the hardfile if you run it. At least, it did for me. I launched it once, it started running, then it did a beep and a restart and the hardfile was corrupted and had to be swapped out. Yeesh. Gonna kick that game off the image ...

Everything can be accessed from the archive.org page for the pack now. Search for MacPack for FPGA.

Minor additional sys updates. I've submitted a pull request.

Oops, I saw that jordi had actually mentioned the sound works fine in Mini vMac earlier in this thread. It does for sure appear that the tone generation referenced previously in this thread is unimplemented in the core.

meauxdal

Found a few schematics for old Apple stuff here: https://tinkerdifferent.com/resources/ Oh, it might help fixing core sound fx? It's broken since forever in older games I didn't peruse too closely, just saw some schematics and technical documentation that hadn't been linked to here previously. Whether or not they are actually relevant to the curre...

meauxdal

Same as above but built with latest MiSTer framework, please test. Seems to work fine on my end.

MacPlus core test build with corrected aspect ratio attached to this post. Please test and report any issues. I'll try and spruce up the (outdated) readme as well before submitting a PR.

Edit: I don't really know what I'm doing but I'm trying to also update the framework - we'll see how that goes

If you're just asking "can you perform speedruns on the core", well, yes. Presuming the game works, tricks and glitches relating to the speedrun will almost certainly also work. There are observable differences from real hardware completely aside from games that don't work or crash. In most cases, there is somewhat better performance on t...

I appreciate the MacPack feedback. Some updates on that front: Been doing testing on the archive of disk files. Was never entirely happy with the organization for that in previous releases, so the next one will make it much easier to find what you want (merging 400K and 800K folders, one title per directory with better naming, culling some duplicat...

No, I'm saying the early compact Macs (with built-in monitors) are very obviously not 4:3. They are extremely close to DAR 3:2. The intended PAR for Macintosh Plus is 1:1, though there of course can be variances and the actual mathematically "correct" DAR might not give exactly 1:1 PAR. I don't have the ability to calculate the mathematic...

meauxdal

For now, to correct the issue, add these lines to your .ini file

Code: Select all

[MacPlus]
custom_aspect_ratio_1=256:171

Then apply the aspect ratio in the core and save your settings.

meauxdal

@meauxdal First, I'm not sure you're taking DAR into account...square pixels in memory are not necessarily represented as such on-screen due to the limitations of analog display technology. That being the case, might I suggest you create a custom aspect ratio for the MacPlus to visually confirm your suspicions? It may also prove to be a suitable l...

meauxdal

I've had this suspicion for some time, but at this point I think the aspect ratio is simply incorrect on the MacPlus core. The pixels should be square. The aspect ratio should be 256:171 for 1:1 pixel aspect ratio (PAR). For some reason the core is currently squeezing the screen into a 4:3 shape, which is not correct for the early compact Macs. I'v...

I speedrun some N64 games. I'd say the most likely outcome for legality of the MiSTer core in speedruns is that most game communities won't explicitly allow it, at the very least not as a competitor to original N64 hardware. This is especially true for RTA (real-time attack) speedruns, or runs where final time is the real time elapsed during a sing...

Just checked it again, I’m not getting music ingame. That’s with the latest build. Music has worked in Goldeneye since the game started working (back when TLB was added, December iirc), and is still working fine on the latest core. It's something with your setup. Try resetting core settings/verifying BIOS & database/deleting .cfg files. It's a...

I've uploaded a new version of the pack. Lots of optimizations, improvements, etc. I'm quite happy with this one. The search term should be: MacPack for FPGA

meauxdal

This is one of my favorite alternative cores on MiSTer. I love being able to hear music I've heard for decades in new ways, and some tunes really sing with the right settings.

Please note, I don't recommend using the 010 or 020 instruction sets in conjunction with the SE ROM. It seems to cause hardfiles to corrupt. Here's a short video showing what can happen if you don't heed this warning ;) https://www.youtube.com/watch?v=DDetZDiLoNw Seems like a possible core bug. I've let alanswx know about it, hopefully we can figu...

And yes, I'm still working on this. Sorry for the rapid iteration and multiple releases, not trying to waste anyone's bandwidth! c: The 20240226 release has a ton of new stuff over the 0219 release, which is pretty much just the last 2021 version with an additional virus sweep. There have been many newly cracked classic Macintosh games in the last ...

New version! The thing to search for is 'MacPack-20240226 for FPGA'. Now with Macintosh SE ROM support.

Please note, I don't recommend using the 010 or 020 instruction sets in conjunction with the SE ROM. It seems to cause hardfiles to corrupt.

It only gives me an error beep when I try to change ini files. Are your ini files named using the original convention (MiSTer.ini, MiSTer_alt_1.ini, MiSTer_alt_2.ini, etc.)? Or are you using the newer naming that allows arbitrary labels (MiSTer_CRT.ini, MiSTer_HDMI.ini, etc.)? Off-topic, but could you please help me find information about this? I ...

Someone pointed out to me that there were some old Macintosh virus files in some of the HyperCard stacks in the last release of I did of the big games/apps pack. Those have been sanitized with Virex 6.1, and the pack has been reuploaded. Search for 'MacPack-20240219 for FPGA' on a certain archive site.

An in-game time WR speedrun for the game popped up in my YouTube feed lately. The final score for this run is 49,200,490 - maybe you can glean some tactics from the video?

OEM PS2 pads work on PS1 hardware. I don't have a SNAC/SNAX but in theory they should work.
