Back to Skool: Pokes

To make HAYLEY amenable to any number of kisses:

In addition, to make HAYLEY do all of ERIC's lines for him on each kiss:

To extend the range of the catapult from 13 to N:

However, this doesn't extend the 'hit zone' of the pellet (the portion of its flight where it can hit something). To change the hit zone from the last 4 stages of its flight to the last M stages (M=N-6 is a good choice):

POKE 30388,M+1

Finally, to make the normally invulnerable ALBERT susceptible to pelleting:

POKE 30441,6

Unhide the bike

Before ERIC writes the bike combination on a blackboard, the bike is actually hiding at x-coordinate 224. To change the bike's initial x-coordinate from 224 to X (so that it's visible from the start of the game):

POKE 54049,X

Any choice of X in the range 0-189 will bring the bike into view.

Walk through doors

To enable ERIC to walk through specific doors:

POKE 28336,24 (left study door)
POKE 28343,24 (right study door)
POKE 28387,24 (science lab storeroom door)
POKE 28408,24 (skool door)
POKE 28415,24 (skool gate)

Walk through walls too

To enable ERIC to walk through any wall or door:

POKE 28315,24
POKE 28316,31

But now when ERIC walks through the far left wall in the boys' skool or the far right wall in the girls' skool, you lose sight of him. To make the screen scroll however far left or right ERIC goes (and therefore reveal the "no man's land" between the two skools):

POKE 28191,0
POKE 28203,0

But this also reveals a limitation of the routine at 24880: the SRB is not updated correctly when the leftmost column of the skool on screen is 232, 240 or 248. To fix this:

POKE 24893,47
POKE 24894,131
POKE 24896,0
POKE 24897,254
POKE 24899,63
POKE 24902,2
POKE 24904,47

Now you may notice that some of the little boys stop moving as ERIC approaches the far left wall of the boys' skool. This is because the routine at 25296 does not move certain minor characters depending on which part of the play area is visible.
