The issue probably has to do with resource (fork?) compression/decompression. This feature was (for no good reason?) removed in 9.1. There's quite a list of software that got affected by this, such as After Dark, and possibly also Power MachTen, although the former got a patch fix for it, and the latter even an official patch fix.

If you can bring this ability back to 9.1, and thus also 9.2, 9.2.1, and 9.2.2, it might fix the problem entirely, and also fix a bunch of other software.

I don't think it has anything to do with the "ROM" file: if you install Mac OS 9.2.2 on an Old World ROM machine (using i.e. OS9Helper), you will most likely encounter the exact same issues.

Also, when you ask for "version 9.1 of the ROM", do you mean a ROM file included with some release of Mac OS 9.1, or a ROM file whose version is "9.1"?

i don't think it's about resource fork compression, because i have 9.1 running on my pismo and hellcats runs just fine after removing some unneeded monitors extension or something (i can't recall but i can dig it up).


my '9.1 ROM' i meant the ROM file included with mac OS 9.1, not a spoofed version. i tried copying my 'Mac OS ROM' over from my Pismo and my ver 1 power mac G4 but it resulted in an error after the happy mac.

Being an avid Hellcats fan since the 90's (perhaps THE essential 90's Mac game for me personally :-) ) I've been following your thread, hoping you could find a solution. (note to myself: My Pismo runs 9.0.4 so I need to check if it runs on there.)

Have the sources for Hellcats ever been showing up somewhere? Has anyone tried to contact Eric Parker about it? Taking the sources and recompiling the game might be the easier way than getting a 9.1 ROM working on the Mini? (though that would be an interesting project and one I'd love to see!)

i distinctly remember trying to contact the original author a few years ago but i only got undeliverable mail messages so i gave up. also i'm really not a developer, i can only use MPW with tutorials and examples (i'm a UNIX sysadmin by trade), so i thought it would be easier to replicate the environment where hellcats runs properly. i even thought of compiling mini vmac's macII version for OS 9 so i can run it in a VM and be done with it, but i had to abandon that because the mini vmac author said OS 9 as a host is no longer supported in the build system..

Very cool!

Wish more knowledgable folks would do this - buying up broken machines, fixing them up and releasing them out into the wild again. Thumbs up!

I hope that the OP will become a major donor when it comes to covering Knezzen's expenses to run this place.

Agreed!

Or rather... (wait for it...)
