Its a little known fact that I’m a big Metal Slug fan. Its little known because ive only recently got into playing it on a friends Neo Geo CD system.
It came as a great surprise when Darksoft announced that Metal Slug 6 has been converted to the NAOMI as I had never played it before and had also seen nothing of it.
Im happy to say it works perfectly and have had a fun morning shooting aliens.
Thanks to Darksoft for continuing with this project and for once again introducing me to more hidden gems from a system I’m likely never to own again.

Just a quick note.
The PLD Archive has now been split into two, A-M & N-Z.
This needed to be done as the table was becoming slow and unresponsive for us when we are updating it and we were fearful of a database crash.
Nothing else has changed and all the entries should still be present but you will need to select the table you want to see from the page.
Thanks

Got this PCB as usual from Ebay as faulty, seller said it was missing some sounds.PCB was in a clean state:
Once powered up, actually, all sound FXs were present but music was missing at all.Sound hardware is formed by a Z80 CPU which controls a YM2203 FM synthesis IC coupled with a YM3014B DAC and all sound (music+ FX) are pre-amplified by a NEC uPC4556C OP-AMP before going to the main MB3735 amplifier.Connecting the analog output (pin2) of the YM3014B to an external amplifier I could hear the music, this was still present on the OP-AMP input (pin5) but not on the output (pin7).So, I desoldered it and tested it in my chinese tester which reported it as good.But this did not convince me so I replaced it with an equivalent Mitsubishi M5218 and this was the winning move since music was fully restored.
End of job, see you next repair!

Today I dumped and tested all the PAL chips from a Space Gun PCB.
These are all in MAME already but I dumped them from strykr’s PCB.
