I tried running the Atomiswave convertions and they run both on DEMUL and Makraon Naomi.
This leads me to believe that the reason why some games still don't
boot on the real Naomi, but boot on the emulators is related to the way in which video is
initialized. Maybe they use another trick to fool Naomi or DC.
It works faster and with better sound in Makaron for Naomi, but maybe emulation is not so accurate as with DEMUL.
In Demul Choose in the Menu--> Run Naomi (don't Run Atomiswave!) --> Load Decrypted rom --> choose any of the converted games I've released.
Unfortunately afaik none of them has a debugger, so they can't help me much.
For the non-believers, you can try yourself the not finished conversions of Metal Slug and KOFNW in any of the emulators that I mentioned befor. The links here:
More updates coming soon.
