Last year I've made several patches for BM1. Most of them are status window-related. Let's see them:
For Bio Menace 1 (freeware release!):
This patch removes the CLIPS completely including the lines around it.#Remove CLIP text and counter completely
%patch $6342 $90 $90 #CLIPS disappeared
%patch $6383 $90 $90 #CLIPS disappeared
%patch $6387 $90 $90 #CLIPS disappeared
%patch $63A2 $90 $90 #CLIPS disappeared
#Lines around the CLIPS counter removed
%patch $6352 $EB $13
This is the patch for the loading screen.#Loading screen
%patchfile $27F47 "BM1LOAD.BIN"
Keep in mind that - unlike the Keen 4-6 loading screen - Bio Menace loading screen can fully be edited, which means you can edit the entire loading screen.
In short: inverted colours for the LOCATION background and text.#Location text is white, background is black
%patch $5EB9 $90
Inverted colours for the LEVEL background and text.#Difficulty has black background and white text
%patch $6011 $90
This complex patch removes the gold key and its counter totally.#Lines around the gold key and its counter removed
%patch $6181 $90 $90
#Gold key sprite removed
%patch $616D $90 $90
#Gold key and its counter removing (must be used in all cases or you will only see a black square instead)
%patch $614C $EB $13
This patch makes the game's camera scroll up or down to Snake at the beginning of the level, depending on how big/small the level is and where (top or bottom of the level) Snake starts the level.#Game camera scrolls up/down to Snake at the beginning of the level
%patch $64A2 $90
This patch makes the status window completely black, including the entire game screen as well.#Completely black status window including black screen background
%patch $5E7B $1A $1A
