Rohrleitung Gate is a project I started in 2012. Initially I didn't want to make a huge project, but now it's a 100+ KB ROM.
It probably should have been released in 2013, but after I completed the custom background mechanics, the lack of graphics prevented me from releasing it, and as of now this part is still very underdeveloped. Since I've shifted my focus towards Mario Gaiden
, it's time to put the finishing touch to this hack and work on Mario Gaiden. (In fact that project borrowed several of the ASM changes from this hack)
Main contributor is me, co-contributor goes to GAP (GAP_15 on Baidu Tieba) for designing a few stages.
The game is a puzzle-solving game. It's not a maze like Extra Mario Bros. The course is linear, but almost every stage is a puzzle.
Current changes include:
-- Forward&backward scrolling within 2 pages.
-- Multi-layer background effect in various stages.
-- Koopa shells can break bricks and bump into hidden blocks, revealing them.
-- Enemies can appear on the first page.
-- Konami code(Up Up Down Down Left Right Left Right B A) can be entered on the title screen, increasing the num of lives to 31 and activating hard mode.
-- Recomposed soundtrack. What's significant about the soundtrack: SMB only used the 4 traditional channels, but here I've made use of the DPCM and VRC7 channels. A PCM sound effect is also included.
-- More minor effects.
The background I used in a stage. Note that it's actually a multi-layer background: The stars won't move, the hills move at 1/2 speed, others move normally.
(It's not raster scroll of course, it's done by changing the CHR tiles. The limitation is that the background gets repetitive. If a part of the background doesn't use the multi-layer effect, that part can be completely user-defined.)
The infamous fake wall.(This is not a new effect.)
A puzzle-solving stage. The pipe shown is the exit, but it's blocked. (Things are not so simple here... Currently, this is the best stage I've designed in this project. Note: Edits are made to this stage later to fix some issues
