Got the Dump but is copy protected. Hoping my friend can crack it to release it to the public. Bought it off Mercado Libre by my friend in Brazil which was able to get a correct dump. Only pirate left to dump are Final Bout, and unlicensed original Squirrel King (working on this one with the actual copyright owner).
Seems like it wants to detect a custom chip. These chinese releases have a weird copy protection. The game is not official.
SJ: ...and even the official ones occasionaly had additional protection beyond CIC/SRAM. Another common one is a frequency check.
I've had a dump of this for a few years now. Got my cart dumped back when I also had my carts for other things that are out there now dumped (Digimon Adventure for SNES, Pokemon Gold/Silver for SNES, Tiny Toons 3 for Genesis, etc.). We never got the protection cracked though, Looking back at it I should have made more an effort heh. I'm getting a port of Squirrel King on SNES in the mail soon. Only just recently learned it existed. Hoping it dumps with a Retrode.
Ah of course, forgot about that. I've seen some games that show an error message when confronted with a 'unofficial' controller, at least I managed to trigger them when working on my TAS bot. Also the SuperFX chip would talk to the CIC so you can throw that one in there as well. Real curious to see what copy protection the chinese bootlegs use, any chance of a picture of the board?
It had leftovers from another game at the end of the ROM, maybe A Bug's Life if I'm not mistaken. As mentioned already all the unlicensed SNES games have some type of copy protection on them. If you've got a copy that doesn't, then you've got a counterfeit made just within the past few years made from a patched ROM.
