Recently, Simon sent a PR to patch 24bit ROM frame buffer. I poked around Mac SE ROM and fixed emulated hard drive in ROM patch.

If you want to run System 6 using 24bit ROM like mini vMac in BII, give a try on my branch:
https://github.com/rickyzhang82/macemu/tree/pr-fix-emulated-hard-drive-in-mac-se-rom

So far SDL doesn't work. It used XWindows DGA extension. I confirmed it works in Mac and Linux host.

To build it, you'd better use build.sh in Basilisk/src/Unix directory. In pref file, limit your mem to 4MB, screen to 512x384 and CPU 68000 (which is 0)

To replicate my claim, try the pref file and ROM below

Pref file:

Quote:
displaycolordepth 0
screen win/512/384
disk /Users/Ricky/repo/68k.Mac/BasilikII/DiskImage/MacImage.6.0.8.dsk
seriala

udpport 6066
rom /Users/Ricky/repo/68k.Mac/BasilikII/ROM/MacSE.ROM
bootdrive 0
bootdriver 0
ramsize 4194304
frameskip 0
modelid 5
cpu 0
fpu false
nocdrom true
nosound true
noclipconversion false
nogui true
jit false
jitfpu true
jitdebug false
jitcachesize 8192
jitlazyflush true

keycodefile /Users/Ricky/repo/68k.Mac/BasilikII/keycodes
mousewheelmode 1
mousewheellines 3

ROM
MD5 (MacSE.ROM) = 9fb38bdcc0d53d9d380897ee53dc1322
MD5 (MacClassic.ROM) = c229bb677cb41b84b780c9e38a09173e

I saw you mention something about SDL2 implementation on the dev mail list; is there any progress on that?

No, it is not related to SDL2. I'm asking for a Macintosh video driver documentation that got lost in web archive.

Computer graphic is really not my expertise. It took me quite some time to fix SDL v1 for one bit per pixel. I'd stop from there.

The experimental branch below include patch from emulated hard drive, SDL and frame buffer fix.
