Hi, your port of minivmac works on my powerpc.

You might want ${V} in SITES = .../minivmac-${V}/

portcheck(1) found 2 issues with your port.

1. There are $OpenBSD$ lines in patches/. You can delete them,
we stopped putting $OpenBSD$ in ports.
2. The port Makefile has a long line, more than 80 characters.

You can use backslash \ in make(1) to continue long lines. I would
also use && to tell sh(1) to stop if a command fails, like

do-gen:
cd ${WRKSRC} && \
cc setup/tool.c -o setup_t && \
./setup_t -t ${SETUP_TARGET} -cpu ${SETUP_CPU} > gen && \
sh ./gen

Might not need "chmod" before "sh ./gen".

make(1) can expand ${MACHINE_ARCH} in variable names; you might be
able to simplify the arch logic like

SETUP_FLAGS-amd64 = -t ob64
SETUP_FLAGS-i386 = -t obsd
SETUP_FLAGS-powerpc = -t obsd -cpu ppc

and run "./setup_t ${SETUP_FLAGS-${MACHINE_ARCH}}". If someone wants
to add another arch, a -cpu list is in
https://www.gryphel.com/c/minivmac/develop.html

This port ignores CFLAGS and uses cc -Os. I would not change this;
patching -Os to CFLAGS looks too difficult.

My powerpc is a Mac PowerBook G4 from 2004, which is now emulating a
Mac Plus from 1986. I spent a few hours on my amd64 to learn minivmac
and prepare some disk images. (My amd64 has Firefox, which can run
another Mac emulator, Infinite Mac. I used Mac OS 7.6 in Infinite Mac
to extract 2 .sea.bin files and to convert 1 archive from StuffIt
.sit to Compact Pro .cpt; the old StuffIt Expander 4.0.1 in my
minivmac can't read newer .sit but can read .cpt.) I then copied a
Mac game (disk1.dsk + vMac.ROM) to my powerpc. I used thunar on
amd64 and PathFinder (pkg_add fox) on powerpc to drag files into
minivmac. I used unzip (pkg_add unzip) for .zip files.
