Rainbow Islands Extra (Genesis)
|Rainbow Islands Extra|
Also known as: Rainbow Islands: The Story of Bubble Bobble 2 (Extra Version) (title screen)
This game has unused text.
Investigate each of these. (Tracing this game is quite hard... see Talk page for information that I know).
A subtly modified Mega Drive port of the arcade Rainbow Islands Extra, which is Rainbow Islands featuring rearranged sets of enemies, and music. Your friends are dragons again, and clearly, the only way to save them is by use of rainbows.
- Note: I haven't found a cheat code on the Internet for this, so I'm assuming I was the first to find this... If you have any information, please discuss it on this page's talk page. - Andlabs
If bit 6 of byte $FFE036 is set, the game will register infinite continues, indicated by CREDITS A on the title screen.
Currently, there is no known way to trigger this bit flip in the game itself.
Two sets of seemingly unused strings are buried among the title/continue/configuration screens' text:
ROM:00004624 dc.b 7 ROM:00004625 dc.b 6 ROM:00004626 aSelectAndPushS:dc.b 'SELECT AND PUSH START BUTTON',0 ROM:00004643 dc.b 0 ROM:00004644 dc.b $C ROM:00004645 dc.b 8 ROM:00004646 aContinue: dc.b ' CONTINUE',0 ROM:00004654 dc.b $F ROM:00004655 dc.b 8 ROM:00004656 aStart: dc.b ' START ',0
ROM:0000466E dc.b $C ROM:0000466F dc.b 8 ROM:00004670 dc.b ' ',0 ROM:0000467E dc.b $F ROM:0000467F dc.b 8 ROM:00004680 dc.b ' ',0
The game reads the two bytes before the null-terminated string. The only string that separates these two is the string "CREDIT" used on the continue screen.
