Proto:Lufia II: Rise of the Sinistrals

In July 2012, ASSEMbler games forum member Jackhead purchased a Japanese Estpolis Denki II prototype PCB from famous prototype collector DreamTR. While attempting to dump the chips with a Willem EPROM programmer, at least one of the chips suffered corruption. With no way to undo the damage, Jackhead resold the prototype to Trevormacro. With some examination of the crash logs, enough of the corrupt bytes were identified to get the game up and running. After documenting a mostly complete playthrough of the game in a forum thread, Trevormacro released the prototype along with an .IPS patch file on July 12, 2013.

The unmodified corrupt prototype has a size of 2,621,440 bytes / 20 megabit (same as final) with the following MD5: d8cc3bdf62e42b3ee95326dee3e910be

The prototype contains significant differences. A textbox displayed during the game's ending includes a date of 7/18/1994, indicating that the build is from that date or later.

Corrupt Bytes

A list of known bytes damaged. See the Notes page for more details. EPROM writing clears bits; the corrupt bytes will have a lower value than their original state.

EPROM 1

000000-0FFFFF

000000 0x00 -> 0x78
004000 0x02 -> 0xFA
004400 0x02 -> 0x03
006600 0x00 -> 0x51
016600 0x01 -> 0x69

EPROM 2

100000-1FFFFF

The corresponding locations of those seen on the first chip don't seem to be affected... More research required.

EPROM 3

200000-27FFFF
