Download Splatterhouse 2 "classic mask" Rick and color hack ROM Hack

Splatterhouse 2 IPS patch
16th April 2016
updated 19th April 2016
by fusaru
made with HivePAL, Tile Layer Pro, GIMP, Bless Hex Editor

==Update notes==
2016-04-16 Japanese version support added

==Purpose of the patch==
Modify the game's colors by to matcch the style of the prequel more closely.
Give protagonist Rick back his original look. Small modifications have also been made with Tile Layer Pro to include a bit more detail here and there, improve the title screen and allow better color usage

==Usage==
Apply the included IPS file to the ROM (e.g. via Retrofreak, Retron 5, dedicated program such as "StealthPatch IPS Patcher").
If you get a red screen, the checksum needs to be fixed. Programs such as ESE FixCheckSum can do this for you.
There are two patches included for each region version: one for Splatterhouse 1 style Rick, one to keep Splatterhouse 2 Rick, both include color changes. 

==Notes==
-My biggest project so far after Tatsujin. This game has a huge amount of colors
-Due to technical reasons it was not possible to include to full zooming mask effect in the SH1 Rick version. The zoom effect is actually prebaked pictures, assembled from small pieces. I'm not capeable how to modify the code that does this. The Japanese version is even less detailed, because it uses less individual pieces to build assemble the picture. Had to improvise quite a bit here. 
-For people that want to do their own colors (sorry if there are spelling mistakes, this is copy&paste from my notes):
NOTE - These are for the Genesis version, not the Japanese version
