So with a little help and some clearer thinking my NES Classic is now completed.
I was really struggling with getting Neogeo games Turf Masters and Windjammers on the system. I've installed mame roms, mame cores and they have all played well.
I tried every core fb_alpha mame2003, minimame2003, every rom possibility, installed bios_template.hmod etc. to no avail.
Finally figured out that the neogeo.zip bios file I was using was actually a mame version, so therefore did not "talk" to neogeo rom/core.
I now have fbalpha2012_neogeo.hmod installed and running both games with the bios_template.hmod with the actual neogeo version of the neogeo.zip bios file inside of it.
Thanks to
@youngtune27 and
@LuckY07 and
@NESjimbo for helping along the way. Certainly was frustrating.
I've come to the conclusion that you need to test lots of cores, and roms to see which ones work best for gameplay and now I have everything I need on this system. I now await for next version of hakchi to see how much more we can possibly do.
Thanks all.
