Games no longer work in MAME

[dciabrin]

Ah! good to know that you found out where you issue was..

Indeed it turns out that I sometimes introduced breaking changes in ngdevkit, assuming that ngdevkit and ngdevkit-examples would always be kept in sync, assuming they would not be a major hurdle. Bad assumption...

I'll try to announce breaking changes more clearly in the future. I'll bump ngdevkit version on the next major change, and tag the commit to ease backtracking in case one needs to troubleshoot something.

I think that ngdevkit is still a moving target, so in the immediate future I'll keep providing binary packages for nightly builds only, I don't think packaging stable releases is worth the effort just yet.

NB: I'm about to push a breaking change by re-implementing the z80 sound driver, to ease the implementation of future improvements.

Thanks for your bug report.

Ah ha, I failed to notice my Makefiles were a few commits back.

At this commit - 547bf6d07870ebe63e36c9e322cdfbfa7cdbd838, the 02-sprites example does not work in MAME.

At the latest commit, it does.

Looks like I need to incorporate the Makefile changes into my game to get it running again, but that's on me.

For completeness, it was padding out the prom that needed to change. Here is my Makefile diff

+PROMSIZE:=524288
 $(PROM): $(ELF) | rom
-       $(M68KOBJCOPY) -O binary -S -R .comment $< $@ && dd if=$@ of=$@ conv=notrunc,swab
+       $(M68KOBJCOPY) -O binary -S -R .comment --gap-fill 0xff --pad-to $(PROMSIZE) $< $@ && dd if=$@ of=$@ conv=notrunc,swab
