What kind of apps don't run on PowerPC/eMac with 9.2.2?

I've been poking around with MacOS9 on an old eMac, and kind of, it just seems like a lot of stuff 'just works.' At least with a day of poking around MacDraw-era black and white apps, I mostly got old stuff running with a few exceptions and everything old that does run is crazy fast. Maybe the problems I did have are due to this hard drive just having a bunch of older files from an old Mac, so the installs might be borked, but I'm not sure. Is there anything interesting or cool that requires a 68K-era macintosh or older MacOS? Software-wise, apps seem to work, the main thing I don't have are floppies, SCSI, localtalk -- mostly hardware stuff.
 
MacPaint 1.5 running on a Mac II under System 6.0.7. It tends to write directly to the classic Mac screen buffer, which makes everything go wrong, when it's no longer 512x342 x 1bpp


8bpp colour ends up looking like this:

It doesn't even work in monochrome mode on the Mac II:

If I play with it too much it might trash application RAM :)

I get other pretty effects running it on the PowerMac 9500 emulation under Mac OS 8.1:

All the little rectangles with blue, yellow and green dots on them, are what MacPaint thinks is the screen, even though the screen is set to 512x384. It's just that with 16-bit colour everything is wrong (e.g black = 0, but on an original Mac white =0).


Finally, switching to monochrome mode allowed the 9500 emulator to run it reasonably well (though it didn't like me copying a selection):

FatBits also works.

Hah, well, so much for Apple 'following the rules' and not hitting the hardware directly. Kind of a pity that macpaint never made it to color
