Zxbdragon found a pirate port of Lord of King, maybe localized to "Axe of Fight". This dump is in the newest GoodNES (3.23b) as 'Lord of King, The (J)[p2].nes', and marked as mapper 23, however that's incorrect.
It has been hacked to use a chip-on-board copy of the VRC2, however, the VRC2 doesn't provide IRQs, and Lord of King (Astyanax) needs an IRQ for split screen. The pirates replaced the existing IRQ structure with a relatively simple CD4040-based IRQ that will fire after 1024 cycles. Banking behavior is roughly the same as VRC4e (0/4/8/C).
Here's zxbdragon's:

* pictures of the cartridge and pcb: http://wiki.nesbbs.com/index.php?doc-view-72
* patch against fceux with support for it: https://github.com/dragon2snow/fceux-du ... 8708e26eda
And the information necessary:
PRG0 SHA1 = 120e203c4f52e63b0af7824d6b894911a6d7a0a
CHR0 SHA1 = ceb6fff70556b2108816ab60f8f9ef2a6ac17aef
MAPR = 900218 (these numbers are silkscreened on the component side and etched on the solder side)
