I thought i'd post since you guys seems excited about the hunchback ports
One thing that will have to be done is a reverse engineer of an exiting game close to hunchback
For hunchback 1 i decided to look at punchy
The jumping code for punchy works like so (look below)
This will work with modifications for hunchback 1 but it definitely will not work for hunchback 2
I will most likely have to reverse engineer two games punchy and fingers malone
punchyjump_cont2:
dec _jump_index
bmi adjustjump_state
rts
adjustjump_state:
dec _jumpstate
rts
init_punchyjump:
ldy #1
sty _punchy_jumpstate
ldy #21
sty _jump_index
rts
punchy_jumping:
ldy _jump_index
clc
lda jump_tbl,y
adc _punchy.y
sta punchy.y
inc $1a ;not sure yet
jmp punchyjump_cont
punchyjump_cont:
jsr update_softsprites
jsr jump_fx
jmp punchyjump_cont2
