The ROM is heavily encrypted for whatever reason; it's effectively a combination between how the NX-85 and the Pac-Man Pocket Player are coded, both of which had unique forms of protection. Here is a decoded copy, created using the EEPROM Pin Swapper (swapping bytes D0 and D1) and the byte-swapping Python code used for the Pocket Player. I haven't tested it fully yet but it seems to work fine.

Extracts for 4 out of 5 of the arcade ports...Scramble is a 97k ROM (32k prg/ 64k chr) on god knows what mapper, so I couldn't easily get that one to work. The other four games are typical NROM.

true, because if i play the multicart rom in the fceux emulator, it got some graphic issues.

UPDATE: i ripped the scramble rom with success.
it is 193kb big (in windows size) and it may not run on mapper 0 but it does run on mapper 4 without problems, except this graphic issue.
