Hi Paul!

A very good work!!!

I’ve translated STRCONS.h to català language, I hope you can include it in future versions.

Thank you very much for this great emulator!

[... translation (lengthy) ...]
=======================================================

(Sorry for the delay replying, due to travel.)

Thank you for the translation! I have added a Catalan page to the Mini vMac website localization pages, with your tranlation (slightly edited). I’ll include it in the next Mini vMac branch 3.6, when that is started (3.5 was recently released).

There are a few issues I have questions about. The translation I received was double spaced instead of single spaced, which I guess is just a glitch of pasting on my feedback page. But there also seemed to be extra spurious tabs and spaces, which may also be such a glitch. Hopefully meaningful characters weren’t turned into spaces and lost?

I made a comment say "STRing CONSTants (for Catalan)" instead of Català, because in this context the english name of the language has been used. And I have the impression that Catalan is the english name for Català?

In one place (for kStrNewFullScreen) I changed “es´à” to “està”. I suspected this was a typo? This was the only place the ‘´’ character appeared. Similar translations nearby used “està”. Googling “es´à” turns up nothing.

Other than that, there is only one new character that needs to be supported by Mini vMac, ‘·’, as in “cancel·lada”.

I changed the copyright line to 2017, and replaced Chir with ArduinoXino. Or are the translations themselves, and not just the structure of the file, significantly based on the Spanish translation, so that he should remain in the copyright line, and also mentioned in the credit comments. (Perhaps, something like “These strings were translated by ArduinoXino, making some use of the previous Spanish translation by Chir.”) (My name remains in the copyright line for the overall structure of the file, including the program names of the strings, and the comments.)

I use Stuffit for Windos:

http://my.smithmicro.com/stuffit-expander-win-download.html?submissionGuid=b52a9cf8-d104-401d-bcea-bacfcb5fc727

It works Ok (not in all files)


The modern version of Stuffit Expander (now from Smith Micro Inc.) is particularly useful in getting started with Mini vMac by expanding a System 6.0.8 image from Apple (as described in the Getting Started page). After that, it is possible to use an old version of Stuffit Expander that runs in Mini vMac.

Hello. I would like to use the system 7 installer files. What do I need to unpack the bin file?


See the System 7.0.1 install images Recipe for step by step instructions.

[previous message]

In regards to the "Abnormal Situation" (OAO4) error I reported earlier, the error is generated immediately upon booting into Mac OS 7.5.5. There are several PowerBook related items in the Control Panels which has me wondering if perhaps I'm using a version of 7.5.5 that isn't fully compatible with a Mac II?

I received an "Abnormal Situation" (OAO4) error with a v3.5.8 build that did not occur using the same disk image with a v3.4.1 build. I'm reporting this because I do not know whether the error is a result of something I've done incorrectly or if there is a bug in the current version of Mini vMac.


Code 0A04 indicates that Mini vMac’s video driver was passed a control code it doesn’t know about. Previous versions of Mini vMac just ignored such control codes.

If you can tell me what you are doing that generates this warning then I can make Mini vMac deal with it properly. (Which is why it is giving such warnings now, so such issues can be dealt with.)

Mini vMac works great, until I try to install Mac OS 7 on it. When I get to disk 3, it spits out the my dsk file (untitled) and prompts me to insert it. When I mount that back in, it spits out the disk 3, works for a while and then asks to instert the disk "untitled". It would help if you (or possibly someone else) figured out how to mount the DSK file as a SCSI hard disk and not as a floppy. Otherwise, you (and everyone else, who helped make Mini vMac possible) did a great job.

Hi, I told you about the Mac OS 7 disk 3 and hard disk issue earlier today. After struggling with the installation, I noticed it worked normally again. It appears that the issue only happens for some data on the disks downloaded from winworldpc.com. I'm happy that I don't have to do the constant disk switching for every disk. Also, I wrote Mac OS 7, but OS 7.0.1 was already installed by me. I used disk images I found on YouTube. WhatI meant to say was Mac OS 7.5. It might be an issue with the disks.


For many installer programs, including the one for Mac OS, what works to prevent disk swapping is to mount all the installer disks in advance. Mini vMac by default can mount 6 disk images at once. But System 7.5 has more install disks than that. You can increase the number of disk images in Mini vMac with the “-drives” compile time option. You don’t need to compile Mini vMac yourself, you can use the Variations Service.

Hi! I found software that crashes under Mini vMac, can you check if Mini vMac can be patched to make it work? The disk image is non bootable, so you have to boot System 4.1 or higher with a ROM that is at least 128K or larger. Here's the crashing software floppy image: [... link to Super 3D 2.0 by Silicon Beach Software on a site with Macintosh abandonware ...]


Do you have any reason for believing this should work on a Macintosh Plus? It doesn’t seem the sort of software that is likely to.

Or are you talking about the Macintosh II emulation of Mini vMac? It is incomplete, many things work well enough, many things don’t. It is suitable for games when it works. It should not be relied on for accurate results for other purposes.

Hi Paul,

Thanks for writing FDisam app. I'm reading Basilisk II source code. I got stuck in their messy ROM patch code. So I use FDisam tool to read original ROM in human renderable way. After importing the PEFORMA from file and rename it into bin, I don't think it disassemble correctly. All lines are treated as DC.L, define constant.

Is it because the endianness issue in the way extracted ROM file or the ROM is encrypted?

thanks

Ricky

Sorry, I didn't see you have another utilities FindCode that tag code segment in ROM.

I used IDA Pro to disassemble ROM. It requires to manually tag code segment as well. Given 1MB size of Performa ROM, I guess that will be some work.

As a programmer, I'm lazy. I want to know:

1. Did anyone try to tag Performa ROM with MD5 hash af343f3f1362bf29cefd630687efaa25?

2. Are there any heuristic way/tool to tag code segment automatically? So assuming that the tagging program run as M68K instruction executor, we provide a start address and all initialized registers. By running ROM, we tag the code at the same time. When hitting logical branch (either true or false), we fork two different execution path from the fork...

I will appreciate if you can give me some advice since you have done this with lots of experiences.

thanks,

Ricky


Yes, FDisasm won’t do anything very interesting without formatting information. Starting with a map of where the code is.

Creating high quality formatting information is very non trivial.

There are some quick and dirty approaches. Starting with just marking the entire ROM as code. If treating data as code is messing up the disassembly of following instructions that you’re interesting it, then you can manually mark that data in the map.

Dear Paul,

big thanks for your work on MiniVMac_II and the build system!

Could you please enable some more RAM for the Mac_II flavour - say 16MB?


It is possible to compile a version Mini vMac Macintosh II emulation with more RAM, but it doesn’t work. A Macintosh II doesn’t have a “32 bit clean” ROM and so will not normally support more than 8M of memory. According to the Macintosh II article on Wikipedia, the software “MODE32” will allow a Macintosh II to use more memory, but only if the optional PMMU is installed, which Mini vMac does not emulate yet.
