I dont remember where is the original chip, a very known 28-pin maskrom labeled as NTDEC.

Check the attached files.
one is the dump of the PRG IC and the nes image is the menu ripped that i use to modify menu names. tileset for text menu is a mess lolo.

Hope its useful for anyone.

NTDEC5IN1.PRG needs a new mapper number. It cannot be filed under mapper number 202 because mapper 202 also has a 16/32-KiB PRG-ROM size switch, which breaks this multicart (Ice Climber vs. Star Force). Number 385 is the next free one (and yes, I am way behind adding 374-384).
