This patch fixes a duplicated room in Golvellius - Valley of Doom (UE). One room design was presumably inadvertently used in two locations. This patch restores what is believed to be the intended room.
This patch also fixes corrupted graphics on an other room's cave.
Overworld is 13 wide by 14 tall. Each screen is 15 wide by 12 tall = 0xB4 bytes long.
Overworld map data starts at 0xC000 and ends at 0x13FFC. At 0xFFFC is a 4-byte gap in map data for paging registers.
The rooms are not arranged in an intuitive X,Y order, the first 9 rooms of the table are from first area of the game. More details below.
Using the X,Y coordinate system from this overworld map: http://www.smspower.org/seganotebook/golvlius/golvmap.html

These map data only deal with what a room looks like. There is a separate table of 7-byte entries which in some order or another: 1.) points to each of these room definitions 2.) specifies what enemies the room has 3.) where the cave entrance is and what tile data to use for it 4.) probably other things too (such as who/what specifically is in the cave)
At ROM location 0x15cb9 is a 7-byte struct beginning with byte 0x8E which should have been 0x7E for missing room C5.
At ROM location 0x15d29 is a 7-byte struct beginning with byte 0x8E. This is probably the 7-byte entry for room E1.
At ROM location 0x15e16 is a byte 0x94 which is the error byte for the cave graphic in room H5.
