Ok, I'll stop nagging after this message for a while.
I added to the Makefile:
timer.o:
$(CC) $(CFLAGS) -mgeneral-regs-only -mno-red-zone $< -o $@
And now it compile.
But when run:
Page fault CR2=0042 in RMCB at eip 6; flags=3016
... error=0004
which I believe was what I was
I have been able to rebuild the game using prebult cross-compiler from
build-djgpp project.
When I add __asm__("iret");
program crash as soon as I launch it.
Sorry not having the error now.
I am trying to:
__attribute__((interrupt))
void timer_handler(void *frame)
{
ticks++;
...
but
about:
https://git.usebox.net/gold-mine-run/tree/src/timer.c
Should the interrupt_handler for 0x1c interrupt, end with an iret?___

Under VirtualBox, sound works (always... sound never worked for me under QEMU).
But always too fast, even if I slow CPU to 1%.
I created a gminer.iso file with:
mkisofs -o gminer.iso gminer
where gminer is the directory where gminer.zip was extracted.
Timer code is at:
Gold Miner game...
Note: I was trying under FDT2308... where you was trying under FDT2310 (need to
check this new release!).
I just tried under MS-DOS 5 (under QEMU with sb16)... like you described...
works sometimes... but always extremely too
Seems for me, it never run if with sound under QEMU ( -device sb16 ).
Esc stop it with an error code.
But it run (extremely too fast!) with gminer -ns
-ns means no sound
Works well under dosbox however...
I think I had tested it only under DosBOX... sorry for that!
Don't know for other
